• Subcommittee A - Cable Construction and Design, 2:00 -5:30 PM – Monday, April, 29th, 2013
  • 2:00 – 2:15 PM - Subcommittee Business/Announcements – Albert Kong
  •  2:15 - 2:45 PM “Temperature and Stress Effects on the Dissipation Factor of XLPE Insulation” E. Groot-Enzerink, M. Talreja, T. Person, P. Brigandi:  The Dow Chemical Company
    Abstract:  As XLPE insulated cables are being designed for higher voltage applications, the sensitivity of dissipation factor to temperature and electric field becomes more and more important.  XLPE insulations were evaluated as crosslinked plaques to characterize the effect of the temperature and stress on the dissipation factor. These plaque results are compared to model cable evaluations using the same set of XLPE insulations. A comparison between the plaque and model cable dissipation factor data is provided, with similar trends demonstrated.  The results indicate that significant differences exist between XLPE insulations.  Two of four insulations evaluated exhibit very low and stable dissipation factor performance under all conditions assessed.
  • 2:45 – 3:15 PM “Validating Reliability Improvements of New Cable Designs - A Case Study of 600 V Self Sealing Cables”  Chris Fletcher¹, Joe McAuliffe², Nigel Hampton³, & Joshua Perkel³ - ¹Duke Energy, ²Southwire, & ³NEETRAC
    Abstract:  The final connection between residential customers and the primary underground distribution system is made using 600 V unshielded cables (often termed “secondary” cables). These low voltage systems can often be damaged during or soon after installation as builders and landscapers complete their construction work. Sometimes this damage results in an immediate failure (dig in) while other times the insulation is just damaged enough to allow moisture ingress and eventual corrosion of the conductor. Cable manufacturers have approached this problem in a couple of ways: (1) tougher insulation materials and (2) self-sealing insulation. This presentation focuses on the latter option’s performance on a multi-year pilot study conducted on the Duke Energy cable system. Included in the presentation are the following topics:
    • (1)    Overview of 600 V Cable Designs
    • (2)    Why 600 V Cable Systems Fail?
    • (3)    Duke Energy goals/strategy for secondary cable system
    • (4)    Crow-AMSAA technique for Performance Evaluation
    • (5)    Results of Duke Pilot Study
  • 3:15– 3:30 PM - Break
  • 3:30 – 4:00 PM “Axial Water Ingress in Watertight MV XLPE Cables” Knut Brede Liland, Svein Magne Hellesø and Sverre Hvidsten :  SINTEF
    Abstract:  When the outer sheath of a polymeric water tight cable becomes damaged, water can enter the insulation system and axial water ingress can occur between the cable core and outer sheath.  The main purpose to include swelling tapes in the design is to stop axial flow of liquid water reducing the probability of water treeing in the insulation. The objective of this presentation is to show results from measurements of the combined axial liquid and water vapor diffusion in a water tight medium voltage XLPE cable. Sensitive relative humidity sensors have been placed within the outer sheath at different axial positions to measure the axial ingress of water. A hole was cut close to the cable end where the water filling was done. Numerical calculations of axial water diffusion were performed on the same geometry. The results show that the axial water vapor diffusion in the cable is slow and after 130 days the humidity at 0.5 m from the water filling position had only increased by about 40 %. The numerical calculations show even lower values.
  • 4:00 – 4:30 PM "The Effect of Contaminants on Aging of TR-XLPE Insulated Cables: An Evaluation on Commercially Produced 15 kV Cables, Part 5" George Valdes – FP&L; Bill Temple, John Smith –GCC; Paul Cinquemani, Pat Coplen – Prysmian Power Cables; Paul Caronia – Dow; Al Mendelsohn -Consultant
    

    Abstract: In 2001, Florida Power & Light (FP&L) initiated a project to quantify the levels of contamination in the cables they purchase by means of a pellet sorter pilot study on commercial extrusion lines. The pellet sorter pilot studies highlighted the presence of unexpected numbers of rejects in the pellet stream of the TR-XLPE insulation used to manufacture cables. The vast majority of particles were loose dark flakes of various sizes, determined to be degraded compound.

    In order to understand the effect these types of rejects or “contaminants” might have on the cable aging performance, General Cable Corporation (GCC), Prysmian Power Cables, and The Dow Chemical Company agreed to participate in a joint project with FP&L. A plan was developed to select some typical “contaminants” based on the findings of the pellet sorter pilot studies and to make commercial cables with laboratory prepared contaminant particles representative of those found in the pilot program. An accelerated cable aging protocol for testing the effect of these particles was also proposed, which after discussions with the ICEA and AEIC groups evolved to using both the Accelerated Cable Life Test (ACLT) time-to-failure test in water-filled tanks as well as the standard ICEA Accelerated Water Treeing Test (AWTT) 1-year cable qualification test.

    The first presentation in this series (Part 1) discussed the history and objective of the project and described very briefly the cable manufacturing and accelerated cable aging tests utilized in the project. The second presentation (Part 2) summarized the technology developed to produce commercial cables with uniformly distributed contaminants and the tests conducted to validate the suitability of the method. The third presentation (Part 3) reviewed the unexpected effect that the cable preconditioning methods used prior to initiating wet-aging had on the initial ac breakdown strength (ACBDS) of the cables evaluated in this project, as well as the results of diagnostic tests performed to identify the causes for the unexpected effect. The fourth presentation (Part 4) summarized the key data and findings from the first phase cable aging tests completed in 2010, utilizing 2 wet aging protocols. No statistically significant effect of added contaminants was observed in the first phase testing results of this project. Numerical differences were observed, however, indicating there may be an effect of the contaminants, though not statistically significant. Six hypotheses were postulated to explain the results, and a second phase cable aging program was initiated in 2011 to address 3 of the 6 hypotheses.

    This presentation will focus on the key data and findings from the second phase cable aging tests completed in 2012. The tests addressed the effect of ionic content of the water used for the aging tests on vented tree development and ACBD results after aging, the effect of preconditioning method, the effect of aging vessel (pipes vs. tanks) in the case of the AWTT, test laboratory, and larger ACLT and AWTT population sample sizes. Key observations and statistical analyses for each test will be summarized. Overall conclusions and recommendations for additional industry investigations will be presented.

  • 5:00 -5:30 PM “Inspection Standards for High Voltage Polymers in the Cable Industry” Oliver Hissmann – OCS
    Abstract:  Nowadays the high voltage cable industry is moving fast because of the changes of the energy sourcing.  To avoid any problems e.g. in maritime cables also the polymers and its quality level are very important.  This speech will present various methods to check the quality of the Polyethylene resin itself, the smoothness of semicon and the contamination control of cross-linked PE.  The high speed pellet scan system PS400 checks any coloured impurity of Polyethylene within the production with a high resolution of 100 µm at throughputs up to 1.000 kg/h including sorting out the contaminated pellets.  The smoothness test detects and sorts out any nips that look out of the film within the calendared semicon with a resolution up to 5 µm.  The Tape Test checks the polished cross-linked PE film for impurities including labelling of the contamination for further laboratory analysis.  These quality control methods are inherent for the production of high voltage cables.

    Abstract: The failure of electrical cables exposed to severe thermal fire conditions are a safety concern for operating commercial nuclear power plants (NPPs). The Nuclear Regulatory Commission (NRC) has promoted the use of risk-informed and performance-based methods for fire protection which resulted in a need to develop realistic methods to quantify the risk of fire to NPP safety. Recent electrical cable testing has been conducted to provide empirical data on the failure modes and likelihood of fire-induced damage. This thesis evaluated numerous aspects of the data. Circuit characteristics affecting fire-induced electrical cable failure modes have been evaluated. In addition, thermal failure temperatures corresponding to cable functional failures have been evaluated to develop realistic single point thermal failure thresholds and probability distributions for specific cable insulation types. Finally, the data was used to evaluate the prediction capabilities of a one-dimension conductive heat transfer model used to predict cable failure.

  • 3:00 - 3:45 "Unusual mechanism of 5 kV Uni-shield cable failure after 22 years of service", Bogdan Fryszczyn, Cable Technology Laboratories
    CCable Technology Laboratories recently analyzed the failure of a 5 kV, EPR insulated cable of Uni-shield construction. The cable, manufactured in 1987 and operating at 2.4 kV to ground failed after 22 years of service. This nuclear generating power station cable was energized about 75% of its service life. Extensive area of insulation-insulation shield delamination was found around the cable failure. The gaps between the insulation and insulation shield contained water and suspended clay fillers. Both insulation and insulation shield were severely degraded in this area.  In about 50% of the cable insulation wall thickness, the organic fraction of EPR insulation was substantially depleted leaving exposed white clay filler. In addition, the clay also underwent a chemical change.  The average age of U.S. nuclear power plants is 32 years and Uni-shield type cables constitute about 15% of their MV cable fleet.
    Bogdan Fryszczyn earned his Masters degree and PhD in Physics from the Warsaw University in Poland.  He started his employment at in the U.S. at Cable Technology Laboratories in 1979 working with Dr. George Bahder on rejuvenation of water-treed cables. To have practical applications, this original idea of Dr. Bahder required finding suitable rejuvenation methods and their implementation in the field.  By the end of 1984 about 30 000 ft of cable was rehabilitated in different utilities either by dry gas flushing of the cable conductor or impregnation of insulation with acetophenone. This was accomplished despite Dr. Bahder’s prolonged illness and untimely passing in 1982.  Over the last few years a considerable amount of his research was devoted to the aging and failures of extruded medium voltage cables and cable accessories installed in U.S. nuclear power plants. Cable insulation in U.S. nuclear plants consists mostly of various EPRs but also, in a small part, includes butyl rubber and XLPE.

  • 4:45 - 5:30 "Measurement of Toxicity Index per NES 713 on cable components separately and when bundled into the proportions of a 1/C 1/0 15kv cable", R. F. DeMair, The Okonite Company
    Measuring the toxicity index of cable components per NES 713 has been limited to testing each component separately. The standard is very specific about the dimensions and mass to be used. The question to be addressed is what happens when you test a cable. Is the toxicity index the sum corrected for volume of all of the components or are there synergies which increase or diminish the smoke index? This paper reports on the toxicity index of the individual components of a medium voltage cable. We then explore the effect on toxicity when we test all four components i.e. (strand shield, insulation, insulation shield and jacket) together in the proportions found in the cable.

    Mr. DeMair has presented papers at previous ACS Rubber Division and ICC meetings on the topics of Flame Retardant Low Smoke systems and absorption coefficient as related to carbon black particle size in LLDPE.
• Subcommittee F - Field Testing and Diagnostics, Monday, April 29, 2013 9:15 AM - 12:30 PM
  • 9:15 – 9:45 AM -  Advanced Condition Monitoring of long 380 kV XLPE Cables in a Meshed Grid,  Luca Fornasari, Alfred Mendelsohn Techimp HQ
    Currently, the DutchTSO (Tennet) is installing a new 380kV connection in the western part of The Netherlands. It involves about 20 km of 380kV XLPE double-circuit cables, equal to 240 km 380kV-single phase cable. Although several 380kV XLPE cable projects have been realized in Europe, the operational experience of this kind of cable in meshed networks is very limited.
    Therefore, Tennet has defined a 6 to 8 year research program, in which the behavior of long 380kV cable lengths on a system level will be investigated. Part of this research program is the engineering and implementation of a Condition Monitoring System. The goal of the monitoring system is to gather the necessary information to enable verification of theoretical models and behavior of the 380kV cables on the Dutch transmission system on one hand, and to provide parameters to evaluate the condition of components and collect relevant data in case of failures on the other hand.
    The presentation will show the system architecture, the sensors and instruments used, focusing on the condition monitoring system. Moreover, the first results of monitoring may be provided, since the first 10 km XLPE cable part will be energized in April 2013, with the monitoring system installed.
  • 9:45 - 10:15 AM - International survey of the use of damped AC (DAC) voltages for testing MV and HV power cables, Ben Quak, Seitz Instruments
    The Damped AC waveform has been used since end of 90s for diagnostic tests on power cables. Based on recent (2012) survey the collected data of the “common practices” will be discussed. In particular the use for after-laying and maintenance diagnostic testing will be presented.
  • 10:30 – 11:00 AM - Differences between MV, HV and EHV cables concerning test procedures, Steffen Fuchs HIVOLT
    Cables designed for different operating voltages are usually designed with an insulation thickness not proportional to the voltage rating. As a consequence the design field strength of the cable insulation increases with the voltage rating. Examples for the average field strength during normal operation for XLPE cables range from 2.4 kV/mm (61 V/mil) for 10 kV cables up to 12.6 kV/mm (320 V/mil) for a 400 kV cable. The maximum field strength at the inner semiconductor will be higher, depending on the ratio of conductor diameter to insulation thickness.
    This has the following implications for testing of such cables, which will be discussed in detail in this presentation: According to Paschen’s law gas filled voids in the insulation require some minimum voltage for partial discharges to occur within them. With higher field strength the minimum voltage will be reached in smaller voids, so tests on HV and EHV cables need to be more sensitive to smaller defects.
    If tests mainly rely on diagnostic tools, for example PD measurement they need to be sensitive enough to detect such small defects in order to prevent breakdown during operation.
    Withstand tests need to have a duration in terms of time and number of cycles to grow such small defects to breakdown.
    There is a maximum field strength of 27 to 30 kV/mm or 685 to 760 V/mil that should be applied for testing of XLPE cables to prevent damage of healthy insulation, which limits the test overvoltage factors for HV and EHV cables, which makes increased test duration necessary.
    These effects need to be considered for on-site testing of HV and especially EHV cables and result in higher requirements for cable test procedures and methods.
    Conclusion: Towards higher rated cable voltages the margin between operating field strength and maximum allowed testing field strength gets smaller. For a sensitive test stresses of sufficient duration and similar type are becoming more important with increased rated cable voltage.
  • 11:00 – 11:30 AM - Online-PD-Monitoring on Power Cables and Accessories, M. Boltze, P. Mraz, F. Werner Doble
    Reliable power network operation is continuously a subject in all areas of the modern life at both the domestic and industrial environment. Therefore the knowledge of the condition of power equipment has an increased importance to assure safe operation of the power network. A major factor in achieving this objective is providing an efficient maintenance of high voltage equipment such as power cables and their accessories. This requires the assessment of the condition of the insulation materials, which are subjected to several kinds of stresses. In order to monitor any dangerous changes in the insulation materials, much work is being carried out in universities and scientific institutes, as well as by power utilities and power cable manufacturers.
    Beside the established partial discharge test of power cables in factories as part of quality assurance On-site- PD- monitoring are more and more requested as tool for condition risk assessment. For this reason sensitive detecting as well as exact localization of partial discharge signals are important requirements for condition assessment. In this context adequate partial discharge sensing is the key question considering the origin of the partial discharge source as well as the knowledge of the insulation design / material.
    A milestone providing suitable onsite- PD- sensor technology on power cables was the development of the directional coupler in the mid-nineties last century used in the field during acceptance test of two 380 KV power cable systems in Berlin, Germany.
    Non-conventional sensors has been developed for higher frequency ranges (HF/VHF- and UHF-range) and approved in field tests over several last years due to the known limitations at site using the IEC 60270 method to decouple PD- signals from the power cable system under online condition.
    This presentation reports on present successful efforts to monitoring PD in the accessories after jointing in the EHV-XLPE cable systems and describes the HF/VHF- and UHF- PD measuring method. Case studies will be presented approving the functionality of the PD sensor technology used under strong site noise conditions.
  • 11:30 AM – 12:00 PM - Combination of VLF and  Resonance Principle  for Withstand Testing of long cable length, Frank Petzold  Hein Putter Daniel Götz SEBAKMT / Megger
    For commissioning and maintenance testing of high voltage cable systems ACR test systems are commonly used. The logistic in using ACR systems is often difficult, because for testing higher test capacities (longer cables) up to 4 or more test systems must be used in parallel. The costs for such testing and necessary space on site are the reason why in a lot of commissioning cases only a 24 hour soaking test at operating voltage is preferred.
    From power utilities worldwide alternative HV test methods are requested. In 2012 CIGRE has established two working groups.  B1.38 to evaluate alternative test methods / HV sources for withstand testing and D1.48 to consider the behaviour of HV insulating materials under VLF (very low frequency) voltage.
    The discussion about other voltage shapes than 20 to 300 Hz AC for withstand testing also needs to consider the capability of the alternative technologies for testing long lengths of cables with high test capacitances.
    The contribution describes a comparison of test power demand dependent from voltage shape and test capacitance as well as the power consumption of test systems for different test techniques.
    Furthermore an optimised technology for combining advantages of resonance and VLF principle is described and case studies of field applications of this technology are discussed.

  • Re-conductoring Pipe Type Cable Systems - John Cancelosi, The Okonite Company
    Abstract: Excavation, duct & manhole installation, permitting, and property restoration represent the majority time & costs when adding new underground transmission capacity. For existing pipe type cable systems, these cost,  can be eliminated by re-conductoring the existing pipe with larger conductors insulated with laminated polypropylene-paper tapes. This short presentation discusses the advantages of re-conductoring and illustrates capacity increases achieved.
