- “Failure of a 138 kV, HPFF Joint Rebuilt Three Times During 54 Years” by Carlos Katz and Vitaliy Yaroslavskiy of Cable Technology Laboratories and Arie Makovoz of Consolidated Edison Co. of NY.The failure took place at the end of a joint that over the years was built and rebuilt on three occasions. The first was in 1962, the second in 1980 and the last in 2004. The failure and the fact that a 1978 cable was used in 1980 provided the opportunity to compare the performance of two different brand, design and age cables. Our presentation emphasizes the methods utilized to establish the condition of the cables after 54 and 36 years of service, respectively. It needs to be noted that there were substantial differences in the cable features; the main of which was the fact that the 1962 cable did not have an efficient moisture barrier.The condition of the cables was evaluated by a series of traditional methods plus a new procedure to determine the presence and location of soft spots. Knowing the location of the soft spots, it became possible to establish the weakest areas of the insulation, where relative disarray in the insulating tapes had developed. A detailed description of the procedure is provided. The failure and soft spots present on the branches of the “Y” joint appear to have been generated, over time, by movement of the cable over the edge of pipe reducers.
- “Polymer insulation: the full life cycle view” by Dominique Le Roux of Borealis Compounds Inc.We commissioned a cradle to grave life cycle assessment to understand the relative importance of the different phase and compare different insulation materials. The study demonstrated that in all cases of grid utilisation, the highest carbon dioxide emissions are taking place during the use phase of the cable while recycling has a very minor impact. The CO2 emissions during use phase are due to the Joule losses. PP based insulation compounds exhibit a thermal resistivity of 4.6 mK/W Vs 3.5 mK/W for XLPE, creating higher Joule losses and hence higher CO2 emission and higher operating costs during the entire operational life of the cable. Before selecting a new insulation material, it is therefore fundamental to understand the implication on all the phases of the entire life cycle of the cable.
- Recent Developments in Peroxide Crosslinked Polyethylene, by Paul Caronia, Jeff Cogen, Tim Person, Yabin Sun, Joon Han, Qian Gou The Dow Chemical Company
Crosslinking of polyethylene provides a means to realize improved performance including thermomechanical properties at elevated temperatures. Compared to thermoplastic materials, a crosslinked network can resist flow and deformation to a much greater extent when the material is heated above the crystalline melting point. Crosslinking can be accomplished in a number of ways, with the most common being the use of organic peroxides as initiators for thermally-activated free radical crosslinking. While crosslinking of polyethylene with peroxides has been utilized in power cable manufacturing for many decades, there are still challenges and opportunities for improvement. Byproducts of the peroxide decomposition need to be removed from the cable to ensure reliable manufacturing quality testing and to ensure that residual gases will not accumulate and compromise the reliability of cable joints. In this presentation, a brief review will be provided of the advantaged properties of crosslinked polymers and the chemistry associated with crosslinking initiated by dicumyl peroxide. Then a novel approach will be introduced in which a new peroxide structure is shown to deliver crosslinking similar to that of dicumyl peroxide, yet with greatly reduced byproducts and with greatly enhanced resistance to premature crosslinking during extrusion (scorch). The new approach to crosslinked polyethylene also delivers excellent electrical properties and holds potential for a new class of improved XLPE-based compounds for the future.
- DC – Just AC at 0 Hz?, by Detlef Wald
The application of HVDC cables in Europe and in North America is dominated by two cable producers and one compound manufacturer for all the extruded systems that have been installed to date. This presentation will try to explain the requirements for an insulation system for HVDC application. It will provide some examples of what to check for when selecting a LDPE base resin and the influence of cross-linking agents and antioxidants that are normally present in this compound. It will be shown that there are differences between the LDPE’s that are available in the market and a guide to a selection process will be provided. Additionally, it will highlight some important treatments that should be done after the extrusion process of these cables.

- 11:00 AM – 11:45 AM “Modular Injection Component” by Don Songras, Novinium
Today it is not possible to perform sustained pressure rejuvenation on an energized cable with dead-front terminations. Unsustained pressure rejuvenation can be performed on energized cables using special injection elbows, but only at low pressure. Until now, sustained pressure rejuvenation, which is conducted at moderate pressures, required that a cable be de-energized and isolated during injection. Once rejuvenation was completed, the cable could be returned to service using standard cable accessories. The new Modular Injection Component (MIC) is the first cable accessory purpose-built and optimized for fluid injection. As well as enabling sustained pressure rejuvenation on energized cables, the MIC system further addresses several other limitations and shortcomings of current injection elbows.
The inner core of the MIC system contains the fluid and prevents it from contacting and being absorbed by the insulating and semi-conductive rubbers of the accessory. The injection port cap locks to keep it from being dislodged by internal pressure and cannot be mistaken for a capacitive test point cap or elbow pull eye. A valve mounted within the MIC sustains fluid pressure in the cable after injection is complete. The valve is opened by the injection cap, which itself only permits fluid flow when the valve is engaged. The MIC interfaces with all standard dead-front elbows and splices, load-break and dead-break, and allows all sizes of 15 and 25kV URD cables to be addressed with just three MIC sizes. Since the MIC is separate from and installed below the elbow, the injection port has full rotational freedom, and length is inherently added to the cable. All injection functions can be accomplished with a hot stick, permitting installation of the component during an outage and injection to occur when the cable is energized.

- 2:15 – 2:40 PM – “First Permanent PD Monitoring System for a 500 kV Underground Transmission Circuit,” by Mirko Melloni, Techimp HQ, Alfred Mendelsohn, Power Delivery Solutions, SK Lee, Taihan USA, and Hunly Chi, Southern California Edison
The first underground 500 kV transmission line in North America was recently completed by Southern California Edison (SCE) Near Los Angeles, CA. The SCE 500 kV underground cable circuit consists of 2 sub circuits approximately 4 miles long, with 2 outdoor terminations and 11 joints on each cable. Due to the criticality of the circuit, and considering that this is the first time a 500 kV circuit was being installed in North America, Southern California Edison decided to install a permanent PD monitoring system to monitor all joints and terminations. The goal was to provide early detection of incipient insulation faults in service and thus avoid the high repair costs associated with unpredicted failures. This presentation will review the key elements of an effective PD monitoring system, including sensors, PD instruments, monitoring and alarm software and hardware, and the communication system among all PD units. It will also describe the installation of the PD monitoring system and the commissioning activities, and discuss planned activities for setting up effective alarms.
- 2:40 – 3:05 PM – “Calculating the Soil Thermal resistivity along a transmission cable Corridor using DTS Data,” by Dr. S. Cherukupalli, BC Hydro

- 3:20 – 3:45 PM – “New techniques to install high voltage cables into ducts,” by Willem Griffioen, Plumett
A technique is presented which is an alternative to the method to pull high voltage cables into ducts using a winch. Instead the cable is pushed inside while at the same time the duct is filled with water under pressure. With the latter a pulling force is applied on the foremost end of the cable using a special pig. Sometimes installation is possible without pig, where the water (which travels faster than the cable then) creates a distributive drag force on the cable, eliminating the capstan effect and allowing spectacular long installation lengths (note that the cable blowing technique which was developed for optical cables in telecom, using the same trick to eliminate the capstan effect, has been used for more than 2 decades now all over the world). The latter technique without pig was proved in different field trials. The technique with pig has been used already in many real installations, mainly in France and Austria. Although here the capstan effect is still there, cable lengths up to 3.3 km were installed in the field in one piece without intermediate access! This could be reached thanks to the synergy of pushing and pulling, the low friction when water is used and buoyancy of the cable in water, especially beneficial when cables with aluminium conductors are used. Also the method is very easy to use. No need to first install a winch line and operation (labour, installation equipment and cable drum) all at one side of the duct route. Last but not least, the cables once installed by the presented method can be transported further through the duct (a next section) by FreeFloating, where a rear pig is attached to the cable (sharing the pressure with the front pig) and the water pushes the cable further (like tube post)! This method has been proved in a 1 km field trial with 14 right angled bends and 3 sinkers! It allows to install cables in sections difficult to access (or not at all). Finally special software has been developed, not only taking into account gravity and the capstan effect, but also the effect of the cable stiffness in bends and undulations in the duct, and under pushing. This software can be used for all kinds of techniques, from winch pulling to FreeFloating
- 3:45 – 4:10 PM – “230kV Submarine and Land Cable Seismic Design and Construction,” by Marvic Verzano, PG&E and Forest Rong, Black & Veatch.
A seismic resistance 230kV XLPE cable system was put in service to improve the reliability of PG&E’s 230kV transmission system in San Francisco. The overall cable system includes 2.9 miles of submarine cable and 0.6 mile underground land cable, to carry a continuous load of 400 MVA (1005A) and a 48-hour emergency rating of 458 MVA (1150A). The design-basis earthquake event is assumed to be a moment magnitude (Mw) 7.8 earthquake on the San Andreas Fault, with a peak ground acceleration (PGA) determined at the 84th percentile motions (1 standard deviation above the median). On land, the three phases of cables were installed in reinforced concrete duct bank, and in San Francisco bay, the three cables were direct buried underneath the bay floor. Various seismic design and construction considerations were included in the civil duct bank, transition vaults, land to water HDDs, and electrical system to make the installed 230kV cable system operational during and after earthquake. The team will share the design challenges and construction experience learnt from this project.
- 4:10 – 4:35 PM – “Empirical Data on Heat Energy Liberated During Arcing Cable and Accessory Faults,” by Andrew R. Morris, Commonwealth Edison
The results of arc flash testing on several samples of underground medium-voltage power cables and splices are here presented, and the resulting incident thermal energy is compared to the values of incident energy predicted by the Lee Method and the method recommended in IEEE Standard 1584. Neither method is shown to be completely satisfactory, as the Lee Method drastically overestimates, while the IEEE 1584 method somewhat underestimates, the incident energy. The data also demonstrate that the incident energy produced by a fault on lead-covered cable is significantly less than that produced on concentric-neutral cable; in both cases, the radiation pattern is shown to be highly directional.
- 4:35 – 5:00 PM – “Design and Construction Challenges of a HVDC Interconnector Across Alps,” by Christian Remy, Prysmian PowerLink Use of HVDC underground cable systems is increasing. The presentation illustrates the design and construction problems being solved for the 190 km long interconnection between France and Italy. Cables run across the alps, in parallel to motorways and railways, using existing tunnels, bridges, viaducts; the complexity of the route is reflected in the complexity of the issues. Thermal aspects consider a huge variety of different conditions and the most critical were replicated for the qualification tests. Electrical aspects include evaluation and management of stray currents, considerations about transient overvoltages, earthing points. Mechanical aspects are relevant to the innovative installation methods. Different countries with different regulations and practices guided some of the design choices. All these parts, aggregated, make the overall project a challenging but exiting experience, which started at design stage and is continuing with the construction phase.

- 9:30 AM – 10:30 AM – “PD Testing of Nuclear Power Plant Cables – Technical Considerations”, Sarajit Banerjee & Boguslaw Bochenski, Kinectrics, Inc.Abstract – An often cited technical concern with regards to MV cable PD testing in a nuclear plant environment is the phenomena of high frequency PD signal attenuation, as a result of aged tape shields. Despite this fact, there is extensive positive field experience in diagnosing PD inducing defects (particularly in accessories) in helically tape shielded EPR and XLPE MV nuclear power plant cables, across both Canadian (CANDU) and US (PWR and BWR) nuclear plants. This presentation will discuss technical guidance with respect to undertaking field PD measurements in aged nuclear plant cable systems, including handling signal attenuation issues (if present). This will include recommended procedures for verifying PD measurement sensitivity, test voltage, duration and test sequence considerations based on utility and factory standards, measurement methodologies/techniques, localization techniques and condition assessment/acceptance criterion. Field and lab implementation examples of these procedures will be provided, and knowledge gaps will be summarized.Sarajit Banerjee received his B.Eng.Mgt from McMaster University in 2004, and MASc. from the University of Waterloo in 2008. He is currently an Senior Engineer/Scientist at Kinectrics Inc. (formerly Ontario Hydro Research Institute), and has over 12 years’ experience in HV and MV cable systems engineering, consulting, testing and research.

- 11:15 AM – 12:30 PM – “Frequency Domain Reflectometry NDE for Aging Cables in Nuclear Power Plants “, Leo Fifield & Bill Glass, DOE Pacific Northwest National Laboratory (PNNL)Degradation of the cable jacket, electrical insulation, and other cable components of installed cables within nuclear power plants (NPPs) is known to occur as a function of age, temperature, radiation, and other environmental factors. System tests verify cable function under normal loads; however, demonstration of some cable’s ability to perform under exceptional loads associated with design-basis events is essential to assuring plant integrity. The cable’s ability to perform safely over the initial 40 year planned and licensed life has generally been demonstrated and there have been very few age-related cable failures. With greater than 1000 km of power, control, instrumentation, and other cables typically found in an NPP, replacing all the cables would be a severe cost burden. Justification for life extension to 60 and 80 years requires a cable aging management program to justify cable performance under normal operation as well as accident conditions. A variety of tests are available to assess various aspects of electrical and mechanical cable performance, but none of these tests are suitable for all cable configurations nor does any single test confirm all features of interest. One particularly powerful test that is beginning to be used more and more by utilities is frequency domain reflectometry (FDR). FDR is a nondestructive electrical inspection technique used to detect and localize faults in power and communication system conductors along the length of a cable from a single connection point. For the measurement, two conductors in the cable system are treated as a transmission line, which propagates a low-voltage swept-frequency waveform to interrogate the cable length. Note that because the applied signal is low-voltage (<5 volts), the test is completely nondestructive and poses no special safety concerns to operators. An inverse Fourier transform is used to convert the resulting frequency-domain data into a time-domain format, which can determine the physical location of signal reflections if the signal propagation velocity is known. FDR detects discontinuities in the electrical impedance that arise due to cable splices or similar changes along the path of the conductor pair. In addition, FDR has the potential to provide sensitivity to insulation degradation by detecting small changes in capacitance between the cable conductors being examined. Example changes that impact the insulation capacitance include exposure to heat, radiation, water damage, corrosion, or mechanical fatigue. The technique is also sensitive to cable bends, the particular lay of the cable in tray, proximity to other cable, and other factors that bear consideration when interpreting these tests. This paper examines various influences on the FDR approach and compares results of three different instruments capable of producing the FDR to assess accelerated aging cable damage among several NPP representative cables.Leo Fifield manages the Nuclear Cable Aging Program at the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) in Richland, Washington where he is a Senior Research Scientist on the Applied Functional Materials team. He studied Chemistry and Physics at Westmont College, and Chemistry and Nanotechnology at the University of Washington. His research interests include predictive understanding and control of process-structure-property-performance relationships, especially for polymer and composite materials. Dr. Fifield currently serves as the Vice-Chair of the IEEE Richland Section PES Chapter. He has one issued patent, multiple pending patent applications, and a dozen peer-reviewed publications with > 1000 total citations.S.W. (Bill) Glass has focused his 40+ year career on inspection and robotic technologies mostly related to nuclear power plant operation, plant life extension, and decommissioning. Following a BS in Mechanical Engineering and an MS in Bio Engineering from NC State University, he worked for 3 years with the Swedish equivalent of NIOSH. He then joined AREVA working in Virginia and France. He served in numerous engineering and management positions rising to the level of Global NDE Technical Center Director managing more than 50 scientists and engineers plus he served as an expert fellow in NDE and Robotics. In 2015, he joined Pacific Northwest National Laboratory (PNNL) as a technical advisor continuing his interest in inspection and robotic technologies. Mr. Glass leads the cable NDE aging management program that has focused on Frequency Domain Reflectometry (FDR), Time Domain Reflectometry (TDR), and various other local and bulk electrical test methods. He has authored more than 100 technical and scientific papers, holds 7 patents and is a Licensed Professional Engineer.
