Subcommittee A – Cable Construction and Design – Monday, October 30, 2017, 9:15 AM – 12:15 PM
- 9:15 AM Welcome
- 9:15 – 9:50 AM – Is there an alternative to XLPE – Detlef Wald, Eifelkabel Consultant for Cable Applications and Pasi Raikisto, HV Cable Solutions
Abstract: Since the 60ies XLPE has been used as an insulation material for AC power cables. In certain countries also EPR has been used as an alternative at least up to 150 kV. Also in earlier years HDPE, LDPE and PVC has been used and the first was used for cables up to 400 kV. The reason why XLPE is now the dominant material for AC power cables is an operating temperature of 90 °C and the higher short circuit temperature combined with low losses. There are new solutions now being discussed that might be an alternative for XLPE.
- 9:50 – 10:25 AM – How Cables Fail – The Myths and Fundamentals – Ben Lanz and Wayne Chatterton, IMCORP

- 11:05 – 11:40 AM – Results of Cable Rejuvenation on Severely Degraded Black Ethylene Propylene Rubber Medium-Voltage Cable –Andrew Mantey, EPRI and Bogdan Fryszczyn, CTL
Abstract: Polymeric insulation of cables operating submerged in water or in high humidity environment degrade due to water treeing. This phenomenon was first observed in polyethylene and cross-linked polyethylene insulated cables. Such cables, manufactured in the 1960’s and early 1970’s, were extremely prone to this deterioration, which exhibited its ill effects (failures) after less than 10 years of service. Cables with rubber type insulation also suffer from this degradation, but much less frequently and are substantially affected after about 30 years of wet service. Such cables were removed from Nuclear Power Plants due to their in-service failures. From these cables, short-length samples, with black EPR insulation, were selected based on their extremely high 0.1 Hz Dissipation Factor and rejuvenation using two liquids was attempted with one liquid yielding positive results. The treatment resulted in greatly increased AC breakdown strength and in decreased 0.1 Hz Tangent Delta.
- 11:40– 12:15 PM Flammability Testing for Low Smoke Zero Halogen Compounds and Cables to Meet Today’s Fire Safety Standards –Jimmy (Yimsan) Gau, Cable Consulting Services and Rodney Ginger, Wire & Cable Consultant
Abstract: The trend to replace halogenated flame retardant materials in cables installed in areas where large concentrations of people congregate and work, with cables containing Low Smoke Zero Halogen (LS0H) ones, has gained support in many regions of the industrial world. Tests to determine the performance of LS0H materials and cables have been established in North America and Europe by standards associations in both regions. Individual standards specific to a country have also been developed by several countries. The best practice in understanding the effects of LS0H flame retardant formulations on fire safety of materials and cables is to run some flammability tests. Flammability tests are incorporated in materials and cable standards to insure that they meet a level of design for fire safety. They are used in lab tests for material selection and development, in tests on wire & cable to meet flammability standards from various agencies, and to simulate actual use conditions. This paper provides a critical review of three lab tests (LOI, UL 94 V Rating, Cone Calorimeter) and three cable tests (UL 1581 VW 1, UL 1685/1581 Cable Tray, UL 1666 Riser) commonly used to evaluate LS0H compounds and cables. It appears that within the same family of LS0H compounds, lab tests on materials can give an indication of a ranking of their performance under actual burning conditions. It also provides guidance in assessing them as candidates for further testing in single and bundled cable tests. However, the correlation of results between lab tests on materials/single wires and bundled cables remains open for further research. The development of such relationships would greatly help accelerate the development of new LS0H compounds. Part of the difficulty in this correlation is the difference in the parameters involved in flammability tests of materials versus cables. The ability to form char and the integrity of the charred layer in combustion also has a bearing on the results.

- 8:40 AM – 9:20 AM – “International type tests and long term tests of shear bolted connectors in accessories” Markus Köbele, Nexan Shear bolt connectors are often used in underground applications replacing the common used crimping technology. The use of this technology in the field is easy going, but there are many things a producer must take care off in order to have a good connection. Type tests are used to set standards for this technology, but a type test can only simulate the behavior of such connection during life time. The topic will cover the design criteria’s as well as the different standards of type tests. Finally, long term tests will show a wider window from the behavior during life time.
- 9:20 AM – 10:00 AM – “Injection Device Choices for Rejuvenating Cables“ Glen Bertini, Novinium The choice of injection devices to deliver rejuvenation fluid to aging cables has changed considerably over the past few decades.

- 10:15 AM – 10:55 AM – “Transition Joint Installation for 34kV Gas Insulated Line “ Tommi Virta, Prysmian Power Cable Systems
PEPCO, the utility of Washington D.C. needed to transition from a paper insulated gas pressurised cable to XLPE. It was decided to install a transition joint between 3/c 450kcmil LPGF 34kV cable and 1/c 3500kcmil XLPE cables to provide a connection from existing self-contained gas cable line to a substation. In addition to LPGF-XLPE transition joint, new XLPE cable segment and termination were installed. The execution schedule for the project was tight, but the transition joint design, delivery and installation was successfully performed in the given timeline
- 10:55 AM – 11:25 AM – “Design and Additional Tests on 345 kV Pipe-Type Joint with LPP Insulation” Milan Uzelac, G&W Electric Co.
Pipe-type cables, at voltages up to 345 kV, have been the preferred cable type in North America from the earliest transmission cable installations in the 1930s. There is still over 3000 miles of the pipe-type cable in the ground in US.
Although extruded dielectric cables are now more common, there is still a great deal of activity in the pipe-type cable systems. Proven reliability, installation in relatively small size steel pipes and options for cooling to improve the circuit rating are some of advantages. The activity is mostly in uprating, relocating and modifying existing systems but installation of new circuits both on land and for significant water crossings is still taking place. G&W decided to provide additional support to activity that is going on in the pipe-type cable systems by designing and testing the 345kV joint for LPP (laminated paper polypropylene) cables. The presentation describes basic design parameters and design tests performed on this joint per current IEEE Standard. It also provides information on additional tests performed on the same test rig at reduced oil pressure.
The joints for LPP cables are not new by any stretch. They have been around since introduction of LPP cables in late 1980-s. The goal of this presentation is to refresh our knowledge on the design of LPP cables and joints and discuss design test requirements per existing IEEE 404 in effort to contribute to the work of the Sub B WG dealing with unified standard for testing high and extra-high voltage cable terminations and joints.
Subcommittee C – Cable Systems – Monday, October 30, 2017, 2:00 PM – 5:30 PM
- 2:00 – 2:15 PM Chairman’s Opening Remarks and Announcements
- 2:15 – 2:40 PM “Cable Protection – Beyond the Time-Current Curve,” by Charles Darnell, Talon Products, LLC
Overcurrent protection devices are timed to open once the available energy is low enough for safe interruption. In the case of instantaneous settings, interruption occurs within a few milliseconds after the current is sensed. In the case of coordinated upstream devices, delays are longer… but usually within 30 cycles. What happens during that brief moment in time can transform “happy conductors” into “angry conductors” and can change the way you look at cable protection. In today’s arc-flash conscious world where perfect selectivity is mandated, time-current curves, interpreted in the traditional manner are no longer adequate tools to optimize the dynamic performance of cable systems. In order to protect electrical infrastructure and personnel and to ensure your designs are robust, you need to understand the physics of cable movement.
- 2:40 – 3:05 PM “Orlando Utilities Commission 115kV UG Line Installation, Impact of Hurricane Irma” by Nigel Wigfall, Prysmian

- 3:20 – 3:45 PM “Rejuvenation Upgrade,” by Glen Bertini, Novinium
Rejuvenation technology has advanced considerably over the last decade. Field and laboratory data demonstrate that modern rejuvenation technology outperforms the venerable technology introduced over thirty years ago. Reliability has improved two-fold and anticipated post-rejuvenation life has doubled. Many cables that were rejuvenated in the late 1980’s through the turn of the century have delivered two decades or more of reliable service as anticipated. What is a circuit owner to do when the previous generation of life extension has fulfilled its role and legacy rejuvenated cable is back in the pool of at risk cables? Of course, the circuit owner can replace the cable at considerable capital expense, or they can upgrade the cable with the next generation of rejuvenation technology. The next-gen fluids include powerful anti-oxidants, voltage stabilizers, stress-smoothing technology, and partial discharge suppression technology that were not available in the older technology.
The case for a rejuvenation upgrade is even more compelling than the original case for treatment. Thirty years of data all but eliminate the technology risk. A cable’s neutral condition has a baseline measurement which can be compared to the current condition. This comparison allows accurate extrapolation to future periods. Next-gen fluids are designed to deal with all significant aging mechanisms including ephemeral partial discharge. A cable’s suitability to be treated is pre-established. Early field results will be reviewed.
- 3:45 – 4:10 PM “Energizing Three Offshore Floating Platforms,” by Bob, Hobson, NKT
Offshore oil industry in Europe has worked to reduce the carbon foot print and lower operational maintenance and personnel requirements on floating offshore oil platforms. The solution was to use land based hydro generated power to operate floating offshore platforms instead of running platform based generators. The land based power transmission used a combination of static and dynamic 3 core AC power cables. This solution has eliminated the carbon emission, eliminated the vibration and reduced the maintenance personal required to maintain the generators that would have normally been installed on the platform and running constantly. This paper presents the technology development and challenges that were overcome to design, build, install and commission long (+100km) AC power cables to power three offshore floating platforms.
- 4:10 – 4:35 PM “Transition Joint Design Considerations,” by Mark Stemmle, Nexans
One of the major challenges for high voltage (HV) and extra high voltage (EHV) system operators is their ageing cable system infrastructure, since in the near future many of the old oil-filled and gas-pressure cable systems need to be replaced. As nowadays extruded (XLPE) cable systems have become standard for new cable system installations, jointing technologies between paper insulated and extruded cable systems were developed by cable manufacturers.
This presentation will focus on design approach for transition joints between oil-filled or gas-pressure cable systems and XLPE cable systems. Further, the type test procedure and the range of type test approval according to CIGRE TB 415 will be discussed. Examples for qualifications and installations of transition joints will be given.
- 4:35 – 5:00 PM “Current Rating Calculation for Different Phase Distances Along a Route,” by Jeayun Joo, LS Cable & System
Underground cable systems are installed in complicated city and long length crossing such as river, road and railway. This makes different cable installation condition even in a same cross bonding system along a route and it leads to an ampacity deduction by a high sheath circulating current even though the section lengths are balanced. This presentation explores basic ampacity calculation factors, sheath circulation current relation with phase distance difference in a same cross bonding system. Also, a mitigation of the sheath circulation current in the system will be presented

- 2:15 PM – 2:45 PM – Title: Safety Enhancements to Nuclear Power Plants Following the Disaster at Fukushima Daiichi, Matthew McConnell Senior Electrical Engineer, U.S. Nuclear Regulatory Commission (NRC)
Abstract: In 2012, as a result of the Fukushima Daiichi Nuclear Power Plant disaster, the U.S. Nuclear Regulatory Commission (NRC) issued Orders to licensees of Nuclear Power Plants to evaluate potential vulnerabilities that could result from beyond design basis external events and to develop plans to maintain or restore core cooling, containment, and spent fuel pool cooling. Since the issuance of these Orders, all licensees have developed “mitigating strategies” plans for those events and over 90% of plants have fully implemented the plans. The NRC staff has reviewed over 80% of the plans and completed its inspections at over 50% of the plants.” This presentation will provide a high-level overview of the NRC’s Orders with a focus on the tiered approach of the mitigating strategies with examples of unique design solutions that were implemented to meet the regulatory requirements.
Presenter Biography: Matthew McConnell is a Senior Electrical Engineer in the Japan Lessons-Learned Division in the Office of Nuclear Reactor Regulation of the U.S. Nuclear Regulatory Commission (NRC). His principle responsibilities involve reviewing and providing technical support for the proposed electrical design enhancements submitted by nuclear power plant licensees in response to the regulatory requirements issued following the Fukushima Daiichi disaster. He also was involved with the development of the post-Fukushima Daiichi disaster regulations, including the new rule to codify the Orders. Mr. McConnell joined the NRC in 2001 and spent the majority of his time in the Electrical Engineering Branch within the Division of Engineering where he was responsible for reviewing license amendment requests that involved electrical design changes at nuclear power plants. Mr. McConnell received his Bachelor of Science Degree in Electrical Engineering from the Pennsylvania State University in 2001.

- 3:15 PM- 3:45 PM – Title: Fire-Retardant Cable Coatings – A Fresh Look into Their Thermal and Electrical Response for Performance-Based Applications, Gabriel Taylor, Senior Fire Protection Engineer, U.S. Nuclear Regulatory Commission (NRC)
Abstract: Flame or fire-retardant electrical cable coatings have been used in commercial nuclear power plants to limit the spread of fire. A limited set of empirical data from the 1970’s provides the basis for regulatory guidance. Over the past decade, nearly one-half of the U.S. nuclear fleet has voluntarily transitioned from prescriptive- to performance-based, risk-informed fire protection programs. Performance-based programs require quantification for the performance of these coatings. Difficulties were encountered using the prescribed guidance in a performance-based context, necessitating a fresh look into the performance of fire-resistive cable coatings. In an effort to quantify the performance of flame-retardant cable coatings, a literature survey and regulatory review of the subject has been performed to provide a historical perspective on the use of cable coatings in nuclear facilities. An experimental series has evaluated the burning behavior and temporal effects on circuit functionality for a variety of flame-retardant cable coatings. The experiments ranged from bench to full scale, using both standardized and non-standardized testing techniques. Ignition temperatures have been measured using a well-controlled convection oven. Burning behavior of coated cables has been measured using a cone calorimeter to determine burning rate, heat of combustion, and other properties. Full-scale horizontal and vertical flame spread experiments have been conducted to determine lateral and upward spread of fire. Finally, the impact of flame-retardant cable coatings on preserving circuit integrity during fire exposure has been evaluated. The results from this experimental series support updates to existing fire probabilistic safety assessment methods and fire modeling input parameters.
Presenter Biography: Gabriel Taylor is a Senior Fire Protection Engineer in the Division of Risk Analysis in the Office of Nuclear Regulatory Research at the U.S. Nuclear Regulatory Commission.

- 3:45 PM- 4:15 PM – Title: Condition assessment of Low Voltage Cables in Nuclear Power Plant with Near Infrared Spectroscopy, Dr. David Rouison, Principal Engineer, Kinetrics
Abstract: Near infrared spectroscopy has been used in CANDU nuclear plants for more than 15 years to identify and assess the condition of low voltage cables. This technology uses a vast library of cable materials to characterize the insulation and jacket materials of these cables. Aging models were developed and correlated with elongation at break data to determine the condition of cable insulation and support condition monitoring activities in CANDU plants. This technique is implemented in the field with more traditional methods such as the EPRI indenter to determine the aging level of cable materials. This presentation provides an introduction to the NIR technology and some recent examples of its use in the field.

Electrical equipment and apparatus used in DC grids are generally subjected to partial discharge (PD) tests under AC in laboratory and for on-field commissioning. Indeed, while under AC a pattern can be derived which may allow PD and noise identification, under DC there is no correlation between PD occurrence and applied voltage waveform, thus noise rejection and identification of the type of defect generating PD is a problem not solved yet. This is the main reason why PD measurements under DC are not performed and are replaced by AC tests. This paper investigates PD recognition and noise rejection under DC field, focusing on techniques which are simple, but effective, and, in particular, robust. Algorithms for noise rejection, based on the well-known TF map, and for the identification of the type of detected discharge phenomenology, that is, internal, surface or corona discharges, are presented and discussed on the basis of testing simple objects and cable models with artificial defects.
- 8:40 AM – 9:10 AM “ In-Service Testing and Full Time Monitoring for Partial Discharge in Shielded Cables”, William Higginbotham, President EA Technology LLC
Abstract : Partial Discharge is a leading indicator of impending insulation failure of medium, high, and extra high voltage shielded cables. Discharge can result from poor installation workmanship, physical damage, contamination, and electrical tree growth through aging. IEEE 400.3 covers the offline and online partial discharge testing of field aged cables. The time, cost, and logistics of doing off-line testing makes it impractical for regular condition assessment. Online testing can be done quickly and inexpensively but does not provide as much information. This presentation provides an introduction to the partial discharge phenomenon in cables. It describes online test systems for periodic surveys and full-time monitoring as well as highlighting the practicalities of sensor placement. Field results from the UK, China, and the US are reviewed. Finally, a comparison between on-line and offline methods is made.
- 9:15AM–9:45AM “Pushing the Interpretative Value of Diagnostic Tests Based on Dielectric Loss Measurements : Exploration Beyond the Classic Criteria of VLF Tan Delta Diagnostic Features” by Dr. Jean-Francois Drapeau
Diagnostic based on the evaluation of VLF Tan Delta are now well established and interpretative criteria in terms of boundaries for overall condition assessment are proposed in IEEE 400.2. The actual criteria are: Mean Tan Delta at service voltage (Uo), Voltage dependence (Tip-Up) between 0.5 Uo and 1.5 Uo and Time stability (expressed in terms of standard deviation of TD values) at service voltage. As proposed now, condition assessment goes as: “No action”, “Further study” and “Action required”. One of the main limitations of the diagnostic resides in the “global” nature of the assessment and, in particular, the lack of ability to “discriminate” various types of (internal or external) defects from each other. For example, with the actual criteria, in case of “Action required” there is no way to know what component(s) of the cable system (cable, splice, termination) is (are) impaired with advanced degradation, nor is there a well-defined means to discriminate what kind of aging (e.g. water-treeing, thermal degradation, shield corrosion) is present within the cable system. This presentation proposes to initially explore some further diagnostic features actually embedded in the detailed VLF Tan Delta numbers. The purpose is also to present some preliminary diagnostic features coming out of methods using dielectric spectroscopy (DS), especially those coming out of Time Domain Spectroscopy that have been studied at IREQ over the last 15 years. A short review of other criteria coming out of Frequency Domain Spectroscopy will also be summarily presented, with details to be provided in a future presentation. Based on some empirical data, with the help of basic concepts of the physics involved in various aging and/or insulation degradation phenomena, the presentation will explore the potential to achieve a more precise assessment of the cable system, in particular in being able to pinpoint if the bad condition is related to cable aging issue or to insulation degradation issues related to accessories.

- 10:30 AM – 11:15 AM .” Effect of water treeing in rubber insulated cables on VLF tangent delta values” by Gary Toman EPRI, Andrew Mantey EPRI, Bogdan Fryszczyn CTL
Very Low Frequency (VLF) dissipation factor measured in the range of 0.5 Uo up to 2.0 Uo is commonly recognized method of assessing insulation degradation due to water treeing in PE and XLPE insulated cables. Over the years a large body of data was accumulated for this type of insulation.
The knowledge of the effect of water treeing on 0.1 Hz tangent delta on rubber insulated cables (butyl rubber, black, pink and brown EPR) is much scarcer as the density of treeing in such insulation is lower and the rate of water tree growth is slower than in polyethylene. It requires about thirty years for rubber insulation to be degraded to the extent in which polyethylene insulation of 1960 and early 1970 degraded in less than ten years. Rubber insulated cables removed from service in US Nuclear Power Plants after about 30 years or more due to their failure or highly elevated 0.1 Hz tangent delta were subjected to laboratory testing. The strong correlation between 0.1 Hz dissipation factor and their AC breakdown strength will be shown in graphical format for butyl rubber and black EPR insulated cables. For pink and brown EPR only a few examples will be shown as the density of water trees in these types of insulation is much lower than in black EPR.

- 138 kV Cable Replacement for NASA’s Supersonic Wind Tunnels by Rick Williamson and Ian Stangle, Marmon Utility, LLC
Abstract: The presentation will discuss encounters and techniques for replacing a vintage (1950’s) 115kV low-pressure fluid filled cable system (three circuits) with new solid dielectric 138kV cable for NASA’s most operational supersonic wind tunnels. The challenges and victories will be reviewed during the removal process and installation of the new circuit. In addition, the newly installed cable will be described that includes specialized requirements for a wet environment, that is a CPE outer jacket needed after removal of the existing LPFF cable from the conduit system.
- Use of Transition Joints to Pre-Install Partial Circuit Upgrade, by Nathan Kelley, Prysmian Power Cables & System
Abstract: Construction sequencing on a substation upgrade project required a partial removal of a very old 35kV SCFF cable. As the circuit was slated to be upgraded to 69kV in a few years, it was decided to replace a portion of the SCFF circuit with new XLPE cables and use a transition joint to complete the circuit. Working within tight sight constraints and timeframes, the project teams expedited design and manufacturing of a unique transition joint and completed its installation. The final configuration will simplify the future uprating of the SCFF line to 69kV, as it will no longer be necessary to perform work in the very tight constraints of the new substation.
- Fault Current Capabilities of Cable Systems for Parallel Temporary Protective Grounds Nigel Hampton, Thomas Lancaster & Josh Perkel
Temporary Protective Grounds (TPG) or Personal Protective Grounds (PPG) are cable systems (cables and clamps) that are used aerially to provide protection for personnel during work on primary equipment. The appropriate TPG must be applied based on the available fault current at the work location. When there are higher fault currents, multiple TPGS must be used in parallel. According to Annex X5.2 of ASTM F-855, Standard Specifications for Temporary Protective Grounds to be Used on De-energized Electric Power Lines & Equipment, users seeking applications for multiple assemblies should perform their own tests to determine the ratings for multiple TPGs per phase for both low and high fault asymmetry conditions. This work seeks to determine the high asymmetrical rating (F855 H rating) for typical TPG sets. The presentation shows the dynamics of multiple TPG’s and the mechanics / modes of the failure mechanisms. Furthermore, some indications of modeling calculations will be provided suggesting how these specific results might be generalized to other situations
