  • Subcommittee A - Cable Construction and Design
    • 8:00AM – 8:15AM - Subcommittee Business/Announcements
    • 8:15 - 8:40 "Investigation of Low Voltage Cable Performance under Overload Conditions”, Yingli Wen, Neil Weisenfeld, and George Murray, Consolidated Edison Company of New York, Inc.
      Abstract: The Con Edison low-Voltage electric distribution networks have provided reliable service for over 80 years. Although the network’s almost 70,000 miles of low-Voltage cable are continually being replaced with new insulation designs, there remains in-service a significant amount of older field-aged cable. System conditions during periods of high load and hot weather contribute to cable failures and the subsequent load-shift to the remaining in-service cables. This condition can lead to short-term overloading of older field-aged cable. This study was initiated to investigate the effects of repeated short-cycle thermal overloads on the performance of field aged Low-Voltage network cables. Three types of cable insulation installed in three different time periods, which make up the majority of Con Edison’s secondary cables, are tested by subjecting the cable samples to load cycling sequences that simulate the heat wave cycles of several summers. All samples are field-aged cables removed from service. Key electrical and mechanical properties are measured prior to and after each simulated summer of load cycling. Visual inspections are also performed before and after load cycling to determine the physical condition of the samples. Results indicate that the cable samples have high retention of electrical properties such as DC insulation resistance as well as AC leakage current and mechanical properties such as tensile and elongation after the load cycle sequences. However, measurement of oxidation induction time (OIT) shows significant reductions in the amount of antioxidant remaining in the cable samples. Visual inspections show no visible physical changes for newer types of cable insulation, but reveal cracks in the jacket of older cable constructions. Our secondary cables are rated five (5) times higher than their operating voltage. Therefore, as compared to electrical properties, thermal aging resulting from overloading has a greater effect on cable life. A closer analysis of the OIT data and its correlation to other factors influencing the mechanical integrity of cable insulation need to be conducted. We plan to report additional findings in future ICC meetings.
    • 8:40 - 9:05 “A New Generation Cable Restoration Fluid”, Wayne Chatterton, Ph.D., James Steele and Rick Stagi, Utilx Corporation

It is extremely safe to work with, has excellent diffusion and solubility properties and has shown excellent restorative benefits. The fluid and a comparison of previous fluids will be presented. The physical and electrical properties will also be presented. A dielectric breakdown study completed at CTL Labs will be showcased. A discussion on its field applications will be highlighted in comparison to other fluids. The future plans for DMDB fluid and completed testing will be discussed.
    • 9:05 - 9:30 “Rehabilitation: The 3R’s”, Glen J. Bertini and Richard K. Brinton, Novinium, Inc.
      Abstract: There are over 2 billion feet of aging underground power cable in North America. This large quantity of cable must be rehabilitated for the circuits to continue to provide a reliable electric supply. This paper provides a strategic paradigm for optimal use of capital to tackle this problem. Re-evaluate, Rejuvenate, and Replace are the 3R’s of an advanced tactical rehabilitation program, which provides the optimum benefit-to-cost ratio. An improved set of materials and processes are introduced to rejuvenate cables with unsustained pressure for the few cases where the more advanced sustained pressure rejuvenation method is difficult to implement.
    • 9:30 - 9:55 “Insulated Conductor Water Blocking Using Super Absorbent Tapes and Yarns”, David Cavassa, Geca-Tapes
      Abstract: The rising number of specifications calling for water blocked cables and the higher reliability levels expected by utilities have led cable manufacturers to review the way they address these challenges. Newly developed nonwoven water blocking tapes and yarns were seen as providing clear benefits and were quickly adopted widely, but remained limited to certain areas of the cable, either by choice or technical or economical constraint. In the recent years, in order to further reinforce the cable protection from the effects of water, manufacturers sought new areas to water block within their cables, such as in the case of power cables, the interstices between the insulated conductor's wires. The presentation will provide an overview of the dry, adaptable solution currently offered, involving the use of specifically designed swellable tapes and yarns.

    • 10:55 - 11:20 - “Exploring TR-XLPE for High Voltage Cables", P.J. Caronia, S.J. Han, J.B. Kjellqvist, Tim Person (speaker), The Dow Chemical Company
      Abstract: Although overhead lines are popular for power transmission in North America, there is a growing trend to the use of extruded cables for underground transmission. One of the key advantages of underground transmission is reduced outages due to extreme weather conditions and lightening strikes. To date, extruded High Voltage cables have utilized XLPE insulation, while for Medium Voltage underground distribution, TR-XLPE has been accepted as the standard in North America. In this study, the key electrical performance characteristics of TR- XLPE compounds were investigated for use in high voltage cables. The use of TR-XLPE in HV cable designs may be able to provide for increased reliability in service.
    • 11:20 - 11:45 “Progress in Mastering the Environmental Impact of an Underground Link”, Pierre Mirebeau and Safiq Virani, Nexans France
      Abstract Since 2000, different studies have shown the interest to use a dedicated software to assess the global environmental impact of an underground cable link. The work presented in this contribution summarises studies already carried out, and updates information on the influence of different parameters about the environmental impact of a link (3 unipolar cables) such as: Influence of the type of earth bonding, Influence of the conductor cross-section, Influence of wire insulation in the conductor, Influence of the type of metallic screen, Influence of the type of installation, Influence of the insulation thickness. In reference to the conclusion of public discussions in Europe about environment, the authors have also used one impact indicator, the Global Warming Index which is mainly characterised by the carbon dioxide emission, to compare the impact of an underground cable link with the one of a truck.
  • Subcommittee B - Accessories
    • 9:15-9:30 – Introduction/Announcements, Tom Champion, NEETRAC - chair
    • 9:30-10:00 “Superhydrophobicity in Power Applications”, Nigel Hampton, Frank Lambert, NEETRAC - A Center of Georgia Tech
      Abstract: In a number of instances contamination of overhead insulators has become a major concern which affects the supply of electrical power. The basic issue is that contamination on the insulator surface gives rise to and elevated leakage current, and if high enough, flashover. So far, various techniques have been applied to address this problem:
      1) Cleaning with water can remove loose contamination, but they are expensive, labor intensive & only short term solutions.
      2) Protective coatings, including oils, grease and pastes surface treatment, can prevent flashover, but have damaging results to the insulator during dry band arcing.
      3) Since the 1970s, silicone coatings have gained considerable popularity both as retrofit solutions and as the basis for the insulator.
      The techniques described above cannot prevent contamination, such as dust, accumulation on coating surfaces, thus these serve to manage the problem, yet none of the above techniques has satisfactory performance in heavy contamination environments. The work described here has looked at the use of superhydrophobic or Lotus Effect coatings to mitigate the development of the contaminated environment. The focus here will be on its use for a variety of external electrical insulation systems.

    • 8:15 am - 8:45 am - Enhanced Fire Performance Energy Cables: Halogen Free Technologies - Dave Kiddoo (AlphaGary Corp)
      Abstract: With ever-evolving requirements for “Environmentally Friendly” and “Fire / Smoke Resistant” cabling for buildings and industrial environments, material technologies are changing at a rapid pace. In standards organizations, regional solutions are now being considered “globally”. The trick is to make sure the total engineering balance of application performance, safety, environmental compliance and cost are each accounted for in new ideas and cabling designs. Historically, specifications in the US and Europe for energy cables have evolved differently. In the U.S., the technologies have been based on XLPE, PE, Nylon and PVC, whereas in Europe, cables are utilizing XLPE, PE, PVC and halogen free materials. Increasingly in Europe and Asia, the trend is to continue to move toward halogen free materials. This presentation will briefly cover the status of evolving European Fire Performance Standards and review the halogen-free material solutions on European energy cables.
    • 8:45 am - 9:15 am - Worldwide Experience with Halogen Free IEEE 383 Qualified Nuclear Power Plant Cables - Lukas von Laue (NEXANS)

    • 2:10 - 2:35 PM - The Impact of Technical Progress on Field PD Detection, Jim Jun Guo and Steven Boggs (Presenter), University of Connecticut
      Abstract: The fundamental issue for detection of partial discharge (PD) under field conditions is the noisy environment in which the PD must be detected. In this presentation, we address the impact of expected advances in relevant technologies, both hardware and software, on PD detection in noisy environments, as well as the time frame in which these advances are likely to occur with a 20 year horizon. We consider two contexts, (i) PD detection in shielded power cable for which a bandwidth of about 20 MHz is common and (ii) PD detection with a bandwidth in the range of 100 MHz, which may be more suitable for PD detection at joints in transmission class solid dielectric cable, as well as a number of other applications.
    • 2:35 - 3:00 PM - Withstand Tests – More than meets the eye, Joshua Perkel1 (Presenter) ,Nigel Hampton1, JC Hernandez2, Miroslav Begovic2, John Hans3, Ron Riley3, Pete Tyschenko3, Frank Doherty4, George Murray4, and Leeman Hong4 - 1NEETRAC, Georgia Institute of Technology 2Department of Electrical and Computing Engineering, Georgia Institute of Technology 3Commonwealth Edison, 4Consolidated Edison
      Abstract: High voltage withstand tests are employed by a large number of North American utilities as part of their reliability programs. In fact, according to a study conducted in 2006 by NEETRAC for the Cable Diagnostic Focused Initiative (CDFI), approximately 33% of the member utilities routinely employing diagnostic tests use some form of withstand. Previous work reported to ICC has described the benefits of withstand tests in terms of future freedom from failures and the added information content when the hold portion of the withstand test is monitored in some convenient way. It is, therefore, worthwhile examining the diagnostic understanding that can become available from the use of elevated voltage on cable systems, or simple Hipots. Traditionally, withstand tests have been thought of as purely the survival through the “hold” portion (Figure 1) where the Passes greatly outnumber the Fails (Figure 2). However, many utilities employing withstand tests typically record a wealth of additional information during each test that can include segment information (length), voltage, leakage current, and, most importantly, when the cable system failed (Vf or tf – Figure 1). This presentation starts with these data (field data obtained from several large US utilities) and explores some of the useful diagnostic outcomes that can be derived.
       

      Figure 1: Withstand test “ramp up” and “hold” phases.

       

      Figure 2: Failure on test rates for different segment length, for the 30 minute test recommended by IEEE400.2.

      The issues that can be quantitatively examined include:
      • Test time (Figure 2)
      • Test voltage • Likely outcomes for different sizes of cable system (Figure 2)
      • The importance of the voltage ramp (Figure 3)
      • Prioritization of different parts of the cable system for future test / actions (Figure 4)
       

      Figure 3: Weibull curves showing two modes of failure during “ramp up” phase.

      Figure 4: Separation of failure on test rates by areas.

      The presentation will conclude with some suggestions as to the operating and recording protocols that will maximize the diagnostic capability of withstand tests.

    • 3:00 - 3:25 PM -  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.
    • 3:25 - 3:40 PM - Break
    • 3:40 - 4:05 PM  - Monitoring Accelerated Cable Life Tests with Advanced Diagnostics, Mark Walton (Presenter), General Cable & Matt Olearchyckz, EPRI
      Abstract: This is the first presentation in a series to show the test results that were obtained in an EPRI study (EP-P7243/C3681) to evaluate the effectiveness of several diagnostic methods. The diagnostics were used to measure the progressive cable degradation over time while ageing in a wet environment under various combinations of accelerated voltage and temperature stress. These diagnostic methods included:
      • isothermal relaxation current,
      • return voltage,
      • 0.1Hz dissipation factor,
      • dielectric spectroscopy,
      • 0.1Hz partial discharge,
      • oscillating wave testing,
      • ac breakdowns,
      • water treeing analyses.
      This presentation will explain the “sudden death” test methodology that was used to generate both time-to-failure data for development of mathematical ageing models as well as periodic diagnostic measurements during ageing for development of mathematical degradation models for each diagnostic. Future presentations will show the response of the diagnostic measurements to the ageing stresses of voltage, temperature, and time, as well as the mathematical ageing models and degradation models for the various diagnostic techniques.
    • 4:05 - 4:30 PM - Measurement of Cable System Loss using Time Domain and VLF Techniques, Jean Francois Drapeau (Presenter), Institut de recherche d'Hydro-Québec IREQ, Montreal, Canada & Jean Carlos Hernandez,  Department of Electrical and Computing Engineering, Georgia Institute of Technology
      Abstract: In the recent months, IREQ and NEETRAC, through the Cable Diagnostic Focus Initiative (CDFI) project, have conducted a joint study on the dielectric response of cables and accessories. In the course of this work diagnostic dielectric loss measurements on a variety of cable systems using two methods, TDS (Time Domain Spectroscopy) and VLF (Very Low Frequency) Tan δ. This presentation will show the results of dielectric spectroscopy combining TDS Tan δ results for frequencies ranging 0.002-0.02 Hz, and VLF Tan δ results for frequencies ranging 0.02-0.1 Hz. The investigation covers reference cables (new TR-XLPE & EPR) , and severely aged XLPE cables. EPR cables were used to investigate the practical issues that can arise with either loos of neutrals or poor contact with the insulation shield. The performance of some poorly performing joints was also investigated using the dual dielectric loss techniques dielectric losses. This enabled the further investigation of the manner in which the dielectric loss contributions from cables and accessories sum to contribute to the total loss measurement made in the field.
    • 4:30 - 4:55 PM - PD Detection during After-Laying and Diagnosis of HV Power Cables, Ed Gulski1, Piotr Cichecki1, Riccardo Bodega2, Theo Hermans2, Paul P. Seitz3; 1Delft University of Technology, The Netherlands, 2Prysmian Cables and Systems, The Netherlands, 3Seitz Instruments AG, Switzerland
      Abstract: The application of PD detection for after-laying tests of new installed HV cables and for diagnosis of service aged cable systems cables is getting more and more attention. For afterlaying tests IEC and Cigre are working on recommendations related to sensitivity check procedures.
      In this contribution important aspects of after-laying testing of transmission power cable accessories using non-conventional techniques are discussed. In particular sensitivity checks which can be used to validate the sensitivity of the system for a certain required PD level are discussed here. Examples of on-site sensitivity verification are presented, before the actual PD measurements take place.
      With regard to installed cables PD measurements are valuable indicators for the quality level of the cable insulation. In particular the interpretation of measured PD levels and localized PD sites in cable accessories and cable insulation is of importance for assessment of actual insulation condition. In this contribution experiences on PD interpretation of power cables in transmission network are discussed.
    • 4:55 - 5:20 PM - NIPSCO’s Strategic Cable Reliability Program using DSD Condition Assessment, Dennis Wozniac, Northern Indiana Public Service Company
      Abstract: Northern Indiana Public Service Company (NIPSCO) has long been concerned with ageing cable system infrastructure failures growing beyond its resource capabilities. Since the spring of 2006, NIPSCO has systematically used defect specific diagnostic (DSD) technology to assess the condition of its worst performing URD cable systems, its target population. The technology has provided NIPSCO with the ability to proactively address this population in a way which minimizes unplanned customer outages and maximizes reliability at a significantly lower cost than traditional wholesale rehabilitation programs. The presentation will include:
