  • 2:00PM – 2:25PM - Subcommittee Business/Announcements
  • 2:25 - 2:50 PM - “Silicone Injection: Better with Pressure”, Glen J. Bertini and Norman E. Keitges, Novinium, Inc.
    Abstract: Moderate pressure injection has been utilized for over two decades and has demonstrated several significant advantages over the low pressure inject-and-soak paradigm. In 2006, sustained moderate pressure injection further advanced rejuvenation technology, increasing post injection reliability. This paper traces the evolution of injection pressure in dielectric enhancement technology and compares the merits of the available delivery methods. The paper goes on to introduce the latest improvements in injection technology, thermally enhanced rejuvenation.
  • 2:50 - 3:15 PM “Verification of LV Underground Cable Insulation Integrity by Air Injection”, Jacques Côté, Jacques Chevalier, André Gaudreau, Pierre Gingras, Mircea Iordanescu, Michel Lessard, Yvan Roy and Janislaw Tarnowski, Hydro Quebec Utilities
    Abstract: The The development of an arc fault on low-voltage cables in an underground duct is likely to have important adverse consequences. The main origin of the phenomenon is most likely a break in the insulation (latent fault). Extensive former studies revealed that arc faults cannot be prevented in a cost-effective manner using an electrical approach, based on anti-arc circuit breakers. We present a new approach which consists in injecting pressurized air in the cable core, involves detecting perforations in the insulation, which can occur during handling and/or installation of the cables on the network. The principal performances of this method were established during the extensive laboratory and site validation. The industrial equipment prototype based on this technology is currently under development at Hydro-Quebec’s Research Institute (IREQ). The aim is to develop a fully automatic test device, which will be able to identify by itself the mechanical integrity of the cable insulation.
  • Break – 3:15 – 3:45PM
  • 3:45 - 4:10 PM - “The Electro-Chemical Basis of Manhole Events”, Lily Zhang and Steven A. Boggs, Institute of Materials Science, University of Connecticut, Storrs, CT; Stavros Livanos, and Graciela Varela, Consolidated Edison, Inc., New York, NY; Aaron Prazan*, Southern California Edison
    Abstract: Manhole event” refers to a range of phenomena, such as smokers, fires and explosions which occur on underground electrical infrastructure, primarily in major cities. The most common cause of manhole events is decomposition of secondary cable initiated by an electric fault. The presentation will address various aspects of the thermal properties of the polymeric materials when subject to electric heating, as these properties dominate the evolution of a manhole event. Though evolved gas analysis, the combustible gases have been indentified under both aerobic and anaerobic conditions. Based on our analysis and knowledge of field conditions, we feel that manhole events can be divided into at least two classes, those in which electrical energy dominates and those in which exothermic chemical reactions dominate. The former tend to develop much more quickly than the latter, which are more likely to affect multiple manholes. At present, we are studying effect of duct air flow on the development of manhole events. Computational fluid dynamics (CFD) is being applied to model the combustible flow evolution in the manhole structure.
  • 4:10 - 4:34 PM - “Comparative Evaluation of 138 kV, EPR Insulated Cable: As Manufactured and After 26 Years (a) In-Service, (b) In-Storage”, Carlos Katz, Cable Technology Laboratories
    Abstract: Early in 2008 a fire at a transformer in a hydroelectric generating station provided the opportunity for removing and testing the condition of 26 years in-service 138 kV, EPR insulated cable. Samples of the in-service, slightly damaged by fire, cable were made available. Because at the time of cable fabrication in 1980, the Utility installing this cable realized that there was a lack of experience with 138 kV, EPR cables, it contracted with CTL to advise on a test program to make sure that the supplier would deliver a suitable cable. As a consequence, data on the original cable was also available. In addition, the Utility delivered for testing a section of the original cable maintained in stores for 26 years. Results indicate that the 26 years in-service, as well as the 26 years in-storage cable, are in excellent condition. The presentation provides the results of tests performed.
  • 4:35 - 5:00 PM - “Impulse Strength Retention for Aged TR-XLPE Cables", A. Mendelsohn and T.J. Person, The Dow Chemical Company
    Abstract: At the Fall 2008 presentation on “Exploring TR-XLPE Insulation for HV Cables”, several questions and concerns were raised on the retention of impulse strength for TR-XLPE cables after wet aging. While many studies reported the ACBD retention of aged TR-XLPE cables, less has been published on the impulse strength characteristics of aged TR-XLPE cables. This presentation will summarize results from several field aged cable studies as well as accelerated aging tests. Field aged cable programs were conducted at Alabama Power, Houston Light & Power, and Orange & Rockland and included measurement of impulse strength as well as AC breakdown strength. Similarly, several accelerated cable aging tests, conducted by CTL/HL&P, CTL/EPRI, NEETRAC, and Dow also included measurements of impulse strength. Overall, the results show that after an initial drop, the impulse strength of TR-XLPE remains level and is generally at least 50-100% higher than the impulse strength of comparably aged EPR cables.
• Subcommittee B - Accessories - Wednesday, May 20, 2009, 8:00 AM - 12:00 PM

• Utility practices are changing to more fully utilize available assets through use of smart grid concepts and technologies.  At the same time, new generation sources with different availability profiles are coming on line.  These evolutionary changes are affecting the cables and cable accessories that are part of the scope of the Insulated Conductors Committee.  Components that have performed adequately in the past are being exposed to new and in some cases more severe loading conditions that result in challenges for product reliability, installer training, and purchase specifications.  The same challenges offer new opportunities for product development and enhancement.  These challenges will change industry standards as utility expectations and application knowledge change and evolve in the coming years.

  Staying ahead of the curve as industry needs evolve will be a challenge for all parties involved.  To get an overview for the scope of the problems, the issues that are known to be present, and the issues that are likely to occur, a group of panelists familiar with the “Issues and Challenges with Connectors, Joints, Terminations, and Separable Connectors” will discuss where we are, where known problems exists, and where we need to be heading to meet the challenges of the future.  As such, this discussion will be applicable to a broad range of topics within the working and discussion groups of Subcommittee B and of the entire ICC.

  The panel session will be on Wednesday morning during the main Subcommittee B meeting.  The following preliminary list of presenters and topics should give a feel for the diversity and importance of these topics.

   

  1. “Jointing and Connector Standards” – Glenn Luzzi, Richards Manufacturing – identify existing standards that apply, differences, issues to be addressed, etc.
  2. “Utility Needs” – Tim Robeson, Progress Energy – what do utilities want from connectors, what are their operating experiences, where do problems exist.
  3. “Interaction of Conductors and Connectors” – Bill Taylor, 3M – issues with strand-filled conductors, oxidation buildup, conductor preparation, installation of connectors on old conductors, performance unknowns/questions that remain.
  4. “Pushing the Limits/New Applications” – Neal Parker, Puget Sound Energy -- dealing with wind farm application issues or possibly “smart grid” with the intent of pushing system components closer to the limits.
  5. “Design Issues with Jointing of Corrugated Shielded Cables” – Kal Abdolall, Powertech Labs – issues related to loss of contact between semiconducting and corrugated shields and susceptibility to corrosion at shield jointing contacts.

  Following the presentations of the panelists, the floor will be opened for questions and a general discussion of these issues and how they should be addressed.

  A technical presentation separate from the panel discussion will be made by Glen Bertini with Novenium, Inc.  The title of the presentation is “Advancements in 200-amp Injection Elbows.”  The abstract provides the following description:  “Injection elbows have been in use for over two decades based on the un-sustained pressure injection paradigm.  Recent advancements make injection elbows safer to use and provide higher post-injection cable reliability.”

    Abstract: Asset managers in electric utilities and transmission companies can utilize non-invasive and non-destructive technology to improve the reliability of their electrical transmission system. Cost savings can be realized by making proper engineering judgments based on in situ cable system condition assessment technique. This technology has been in use for many years with proven success in the field. This presentation covers the defects in the cable system, including those in the joints and terminations that can be detected while the cable is energized. Results of a few cables from the tests preformed in the field are also discussed.
  • 2:40 - 3:15 PM - Discussion on the Underground Portion of Connecticut's Middletown to Norwalk Project, by Peter Tirinzoni, Northeast Utilities and Mohammad Pasha, United Illuminating
    Abstract: The Connecticut Light & Power Company (CL&P) and the United Illuminating (UI) Company recently energized two new double 345-kilovolt (kV) electric transmission line underground circuits in Connecticut. One set of circuits is approximately 15.4 miles long, running northerly from Norwalk, CT to a GIS substation in Bridgeport, CT. The second set of circuits leaves Bridgeport and runs approximately 8 miles northerly to a substation in Milford, CT. While the majority of the route is in city streets, the approved route entailed several water crossings that were accomplished by bridge attachments and horizontal direction drilling (HDD). The XLPE cable for these circuits was furnished and installed by three different cable manufacturers.
    This presentation will discuss the cable route, the issues encountered during procurement and manufacturing of XLPE cables, construction of the UG cable system and the commissioning tests that were performed.
  • 3:15 - 3:30 PM - Break

  • 4:00 - 4:25 PM - HVDC Transmission Cable Systems, by Ernesto Zaccone, Prysmian
    Abstract: The need of a better exploitation of the available world energy resources requires the availability of an efficient transmission grid. In the framework of the rationalization of transmission grid, the development of the electric connections and interconnections is of extreme importance for the most advanced countries and continents with a particular reference to the extension and expansion of the production of energy from the renewable resources.
    For a number of reasons the surplus of production plants and energy are generally located in remote areas that are far from the urbanized and industrialized areas where the energy is really necessary. The availability of an extended and optimized transmission grid is of paramount importance for the power transfer from the production or redundant sites down to the utilization sites. This will play an important role in relation of the security of supply and for a progressive integration of an extended electric market.
    The HVDC transmission systems using the LCC or the VSC conversion technologies offer today an interesting and flexible device suitable for the realization of long interconnections between different grids, enabling the modulation of a high power transfer and reducing most of the problems that could rise by using HVAC connection systems. Important submarine and land HVDC cable connections have been realized and are ongoing by using both traditional and innovative technologies. The presentation is a summary of the most important realized connections as well as the state of the art and the trend for the future of the HVDC transmission cables.
  • 4:25 - 4:55 PM - Chicago Re-trofit Projects………………10 Years Later, by Frank Frentzas, Exelon/ ComEd of Chicago
    Abstract: In 1996 Commonwealth Edison (ComEd) of Chicago started an aggressive cable replacement program. The program consisted of replacing four 138 kV LPFF circuits totaling 33 circuit miles with an XLPE cable circuits in four years. At that time XLPE technology was new to ComEd and the U.S. therefore a lot of studies and full size model were constructed and tested to insure the new XLPE system would work reliably in the existing duct and manhole system. A compact design for the cable and accessories were used to utilize the existing infrastructure. ComEd built on their experience and expended the replacement to other 138kV and 69kV LPFF circuits and recently used the same principal and design for a new 345kV XLPE cable project.
  • 4:55 - 5:25 PM - LADWP 138kV SCFF Cable Replacement, by Vince Curci, LADWP: LADWP's 138-kV underground transmission cable system was installed between 1943 and 1959 consisting of single conductor fluid-filled cables.

  • 8:20 – 8:45 AM - Sensitivity Assessment Procedure for Partial Discharge Measurements on Transmission Class Cables, Mark Fenger, Kinectrics
    Abstract: Over the last decade, partial discharge testing has gained acceptance as a valid diagnostic tool for condition assessment of cable insulation. As a result, PD testing has become the corner stone of most asset management programs. However, the results obtained from a partial discharge test depend not only on the conditions under which the test was performed but also on the test equipment itself including the type of sensor used and its location. The issues related to the relationship between the actual discharge, induced charge and apparent charge is well understood. The issues related to attenuation and dispersion of partial discharge pulses traveling along a transmission line are also well understood. Considering these, this paper proposes a calibration procedure for field-installed cable joints which can be used for assessing the sensitivity of a partial discharge measurement for an installed system using both integrated sensors as well as external PD sensors.
  • 8:45 – 9:10 AM - Degradation Rankings of Various Diagnostic Testing Techniques as a Function of Laboratory ACLT Aging Conditions, Mark Walton, General Cable
    Abstract: Data from this EPRI-sponsored research will present the observed correlation for the degradation rankings of six diagnostic techniques as a function of carefully controlled laboratory ACLT aging conditions on field-aged XLPE-insulated cables
  • 9:10 - 9:35 AM - Recognition of PD Defects in HV and EHV Cable Terminations using the UHF Technique, E. Lemke (Presenting) and M. Boltze, LDIC, Germany; W. Weissenberg, Brugg Cables AG, Switzerland
    Abstract: Most unexpected outages of power cable systems are caused by PD defects in the accessories, such as joints and terminations, due to an improper assembling work. Consequently, the detection of partial discharges after installation is considered as a valuable diagnostic tool to ensure the integrity of power cable networks. For the recognition of harmful PD defects in the extruded insulation of cable accessories, however, a detection sensitivity as low as few pC is required, which cannot be achieved in the noisy environment under on-site condition, if the conventional PD test procedure in compliance with the relevant standards IEC 60270 and IEC 885-3 is applied. To overcome this crucial problem the non-conventional UHF method is increasingly used due to its excellent signal-to-noise ratio.
    This contribution deals with recent experiences in PD diagnostics of power cable terminations using the advanced UHF technique. The sensors developed for any kinds of terminations, such as GIS-cable terminations, transformer sealing ends and outdoor sealing ends, will be presented. Moreover, the instrumentation developed for commissioning tests after assembling work as well as for permanent PD monitoring under operation voltage will be described. Finally typical case studies are presented which demonstrate the capability of the applied UHF method for an early recognition of harmful PD defects under on-site condition.
  • 9:35 - 10:00 AM - 10 kV XLPE Cables to be Operating at 20 kV, a Challenging Process of Upgrading, Willem Boone , KEMA
    Abstract: A utility in the NL wants to investigate if existing 10 kV XLPE cables in the distribution network can be operating safely at 20 kV. KEMA was asked to recommend what different steps have to be taken to make the decision well-founded. The following steps are proposed:
    1. Theoretical study: To consider electrical aging phenomena and related remaining life
    2. Laboratory testing: To perform type testing on new 10 kV XLPE cable based on 20 kV requirements
    3. Long term field testing: To perform long term field test on 100m length together with accessories, including diagnostic testing
    4 Criteria: To develop criteria to justify the decision to be taken.
    In the presentation the different steps will be evaluated in more detail. As this project is still in the preparatory phase, a discussion with the audience on the proposed way to obtain upgrading, is appreciated.
  • 10:00 - 10:40 AM - Break
  • 10:15 - 10:40 AM - Dielectric loss diagnosis of serviced aged HV power cables Ed Gulski, Piotr Cichecki, Delft University of Technology, The Netherlands Paul P. Seitz, Seitz Instruments AG, Switzerland Riccardo Bodega, Theo Hermans, Prysmian Cables and Systems, The Netherlands
    Abstract: This contribution is focused on the application of dielectric loss measurements to the insulation of service aged oil-impregnated HV power cables. In this contribution results will be discussed as obtained in a Dutch project on condition assessment of service aged HV cable circuits. The goal of this project is, by combining available on-site and laboratory diagnostics e.g. tan δ, DGA etc., to propose practical tools for condition assessment and AM knowledge rules generation.
    In particular, both the laboratory investigation of materials from service aged cables and the on-site diagnosis of complete several cable circuits have been used to investigate the dependence between the electrical and temperature stresses of impregnated paper insulation at different aging stages. Moreover by tests on aged paper samples the influence of voltage stress on tan δ measured on samples taken from different parts of cable insulation: close to conductor, middle part and outer part has been investigated. As a result the behavior of dielectric losses in function of test voltage and temperature for paper samples in different age condition has been applied to propose a practical tool to support condition assessment decision processes.
  • 10:30 - 11:05 AM - Partial Discharge Magnitude (Wish you were here), Jody Levine, Hydro One

    • The lumped circuit (ABC model) and the EM field shaper • From field disturbance to propagating pulse
    • What happens during propagation and why integrated charge may still be useful
    • Factors affecting sensitivity and the need for quantitative assessment (and the perils of “calibration” via direct, on-site pulse injection
    • Can the test standard help me know the quality of test?
  • 11:05 - 11:30 AM - Condition Assessment and Failure Mode Analysis of 150kV External Gas Pressurize Cable in the Netherlands, Frank de Vries, Cor de Jong, Alliander, The Netherlands
    Abstract: Knowledge about insulation degradation in High Voltage power cables is very relevant to qualify high-risk systems in the transmission cable networks. Therefore failure mode investigation and operational load analysis are important to support the maintenance and operation decision processes. In the Netherlands about 250km of 30-40 year old external gas pressure cable is in operation. In this contribution the complete process of failure mode effect analysis, condition assessment, on-site analysis and thermal load estimation for external gas pressure cables will be discussed. Finally all results together have been used for the estimation of the technical condition and operational availability of specific cable circuits.
  • 11:30 - 11:55 AM - Some Practical Considerations when determining critical levels for diagnostic data, Josh Perkel, Nigel Hampton; NEETRAC
    Abstract: When first considering diagnostics tests a user will often ask what the dividing criteria are between “good & bad”. At first sight this seems a reasonable request and a simple task to accomplish. However there are a number of issues that can lead to complications and will be discussed in the presentation: • Appropriateness of selected features • Availability of service data • Overlaps in the diagnostic data • Incomplete diagnostic data

• • Overview of the Cable Diagnostic Focused Initiative (CDFI)
  • This session covers some of the fundamental findings of a five year program performed at Georgia Tech NEETRAC to clarify the benefits of performing diagnostic tests on medium voltage underground cable systems. This program was supported by 22 different utilities and manufacturers, as well as the US Department of Energy, with the participation of five diagnostic providers. This project has benefitted from the keen interest of the participants, who provided guidance that led to utility focused, practical developments in approaches to cable system diagnostic testing.
  • This program was unique in that it included:
    • Multiple field tests on utility systems with follow-up on the performance of the system
    • Analysis of historical diagnostic tests on utility systems
    • Laboratory tests using long lengths of aged cable returned from service
  • A variety of diagnostic testing technologies were studied, including Dielectric Loss, Partial Discharge (on-line and off-line), Very Low Frequency Withstand, and combinations of these technologies. Different aspects of the technologies were also investigated, including Damped AC (DAC) Partial Discharge, elevated voltage 60 Hz off-line withstand and elevated voltage VLF off-line withstand.
  • These diverse areas of work have enabled the CDFI to make a number of useful contributions:
    • Established ways to compute diagnostic test accuracies
    • Developed tools to select the appropriate diagnostic for a specific system
    • Began to establish condition assessment values based on field test data
    • Suggested methods for interpreting test data using a probabilistic approach
