• Subcommittee A - Cable Construction and Design - Tuesday, May 24, 2011, 8:00 AM - 12:00 PM
  • 8:00 – 8:15 AM - Subcommittee Business/Announcements
  • 8:15 - 8:40 AM “Verification of Low-Voltage Underground Cable Insulation Integrity by Air Injection”, J. Tarnowski, J. Côté, A. Gaudreau, P. Gingras, M. Iordanescu - Hydro-Québec-Canada
    Abstract: An arc fault on low-voltage (LV) cables in an underground duct may have adverse consequences, as the gases generated by the degradation of materials near the fault may cause violent explosions. At Hydro-Québec the main origin of the phenomenon is most likely a break in the insulation which can occur during handling and/or installation of cables. Hydro-Quebec developed new testing technology and equipment for the detection of insulation leaks in newly installed secondary cables. More specifically, the new verification method consists of injecting pressurized air into the cable core and then monitoring pressure variations within the cable. Prototypes were successfully tested on Hydro-Québec’s underground distribution system. Field test results will be summarized in the presentation. The new instrument will be used for quality control of newly installed cables and for fault prevention, including arcing faults.
  • 8:40 – 9:05 AM “Improving and Controlling the Surface smoothness of Semiconductive Shields”, Laurent Gervat, Sébastien Quinebeche - Arkema, France, Oliver Hissmann - OCS, Germany
    Abstract: A first study presented last year has shown that the use of a particular blend of ethylene copolymers improves the surface smoothness of a semiconductive composition for medium and high voltage conductor shields. A new set of experiments using several other types of carbon blacks show that improvements are more significant using specialty blacks versus general purpose grades. It suggests a dual effect of the copolymer blend: a processing and a dispersing one. The study also focuses on the electrical stress enhancement induced by each protrusion. Data from a new software version of the nip detection system allows the effect to be quantified. Applied to medium and high voltage cable geometries, the calculation gives guidance towards acceptable limits for surface smoothness and how to measure it.
  • 9:05 – 9:30 AM “Temporary Site Cables - The Flexibility to Act More Quickly”, Matthias Kirchner - Nexans Deutschland GmbH
    Abstract: Temporary site cables are energy cables used to temporarily connect equipment in a high-voltage network, e.g. as a bypass during construction or repair and servicing work. This type of cable is available up to Um= 245 kV. Depending on the needed ampacity, different cross sections are possible. Temporary site cables have the same design as high-voltage cables but with a reduced insulation thickness. This makes them easier to handle on the construction site. The conditions under which temporary site cables are used give special requirements to the accessories: they must be easy to use and shall have a wide range of possible applications. Flexible silicone rubber outdoor terminations facilitate use in any position. Thanks to their low weight, the terminations can be operated without an additional support structure. Dry type GIS terminations are also available. Special single or three-chamber drums make transportation to the construction site as well as handling on the construction site easier. The special drum design facilitates safe winding and unwinding of the cable and installed flexible silicone rubber terminations. Depending on customer requirements the length can vary between 50 and 500m. rapidly. If faults occur in overhead lines or cables laid in the ground, temporary site cables make it possible to restore energy transmission rapidly. About possible opportunity to use temporary site cables in emergency case will be reported.
  • 9:30- 9:55 AM "Polyethylene Based Jacketing for Power Cables", William Fajardo – Borealis.
    Abstract: Jacketing for power cables has developed over the years as new requirements emerged from new standards. Polyethylene based materials, mainly LLDPE, are currently the jacket material of choice for North American MV primary distribution cables. Its good physical properties and relative cost are key factors. Bimodal polyethylene is the next step for polyethylene jacketing grades. Bimodal PE can provide excellent processing while increasing performance properties. New areas for jacketing include flame retardants and crosslinked materials. Information on bimodal grades and their performance will be reviewed in this paper.
  • Break – 9:55– 10:25 AM
  • 10:25 -10:50 AM "Failure Mechanism of Medium Voltage Rubber Insulated Cable After About 30 Years of Wet Service", Bogdan Fryszczyn – Cable Technology Laboratories, Inc.
    Abstract: EPR insulated medium voltage cables, operating in a wet environment, have failed much less frequently than XLPE insulated cables of similar age. Recent laboratory testing and analysis of longer lengths of various EPR and butyl rubber insulated 5 kV and 15 kV cables, operating in a wet environment for about 30 years, show that the reason for the cable failures are infrequent, but large water trees. This contradicts earlier studies published in 1996 that concluded that water trees are not the reason for failure of EPR insulation.
  • 10:50 -11:15 AM “Buried Cable Performance in the 2010 and 2011 New Zealand Earthquakes”, John Eidinger -G&E Engineering Systems
    Abstract: The two recent earthquakes in Christchurch New Zealand led to ground failures due to liquefaction. About 100,000 customers have had power service lost due to buried cable failures. Most of the power distribution system uses below ground 66 kV and 11 kV cables. This presentation will highlight failures to oil-pressure filled 66 kV cables and XLPE 66 kV cables, with emphasis on the ground failures and consideration of how the thermal backfill contributed to these failures. Repair efforts for this type of damage are costly and lengthy to implement, leading to long term power outages, loss of N-1 protection for many months, and inability to meet peak loads.
  • 11:15 -11:40 AM “The Effect of Contaminants on Aging of TR-XLPE Insulated Cables: An Evaluation on Commercially Produced 15 kV Cables”, George Valdes – Florida Power and Light, Bill Temple, John Smith – General Cable, Paul Cinquemani, Pat Coplen – Prysmian Power Cables, Paul Caronia, Al Mendelsohn – Consulant
    Abstract: In 2001, Florida Power & Light (FP&L) initiated a project to quantify the levels of contamination in the cables they purchase. A six-month pilot was designed, together with two cable manufacturers, to install the same model pellet sorters on one of their respective extrusion lines used to produce cables for FP&L and to fully characterize the material rejected by the pellet sorters over this period. 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 what effect these types of rejects or “contaminants” might have on the cable aging performance, General Cable, 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 lab prepared contaminant particles representative of those found in the pilot. 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 ACLT time-to-failure test in tanks as well as the standard ICEA AWTT 1-year cable qualification test. This presentation will discuss the history and objective of the project in more detail and describe very briefly the cable manufacturing and accelerated aging tests utilized in the project. Subsequent presentations will summarize: (a) the technology to produce commercial cables with uniformly distributed contaminants and tests conducted to validate the suitability of the method, (b) the effect of preconditioning method on initial HVTT results, and (c) the key data and findings from the various cable aging tests, as well as recommendations for future studies.

  • 2:15-2:45 - “IEEE 592 Standard for Exposed Semiconducting Shields", Thomas Champion, NEETRAC—A Center of Georgia Tech
    Abstract: The IEEE 592 standard was written many years ago when the semiconductive shields of cables and joints were exposed. Most cable are now jacketed, which means that jackets are now applied over joints and portions of elbows. The effect of a jacket on the performance of semiconductive shielding systems has never been evaluated, although most installations now use jacketed constructions.

  • 2:45-3:15 - “Medium Voltage Insulated Connector Testing”, Richard Heavner & Sherif Kamel—TE Connectivity
    Abstract: Connectors for medium voltage insulated cables are currently selected based on conformance to ANSI C119.4 which is a specificaton for bare overhead conductors. Issues with connectors overheating during IEEE 404 load cycle testing have prompted further testing and evaluation. Significant differences exist between the test conditions of ANSI C119.4 and IEEE 404. Qualification of a connector to ANSI C119 does not guarantee performance to the requirements of IEEE 404. Test results and a proposal for new medium voltage insulated connector test is discussed. Richard Heavner received received his Master of Science Degree in Mechanical Engineering from North Carolina State University in 1988. He has been employed at TE Connectivity in North Carolina as a Product Development Engineer for the past 3 years, working primarily on connector design and testing for low and medium voltage application.

  • 3:15-3:30 - Break
  • 3:30-4:00 “The Chemistry of Interfacial Tracking”, Dominique Bolliger , Electrical Insulation Research Center— University of Connecticut
    Abstract: Interfacial tracking is a common phenomenon that occurs in a wide range of high voltage apparatus and frequently leads to electrical breakdown. A review of the chemistry of surface tracking on crosslinked polyethylene (XLPE), ethylene-propylene rubber (EPR) cable compound, and silicone rubber (SR) is given, from which chemical reactions are proposed that can occur in the commonly encountered interfaces of XLPE/EPR, XLPE/SR, EPR/EPR, and EPR/SR. Tracking tests were conducted, and the tracking products were analyzed using FTIR and GC/MS. XLPE and EPR showed carbonization and an increase in cyclic and smaller chain hydrocarbons produced from radicals originating from hydrogen abstraction and chain scission. Oxidation of XLPE was observed, and evidence of a Norrish type II photochemical reaction was found. SR showed evidence of the production of SiO2 and lower molecular weight silicones, and tracking was achieved through erosion of the polymer. Dominique Bolliger (IEEE Student Member) received his B.S. degree in Chemistry from the University of Basel, Switzerland in 2008. He is with the Electrical Insulation Research Center, Institute of Materials Science at the University of Connecticut, USA for his Ph.D. degree in Materials Science.

  • 9:30 – 10:00 AM – CIGRE WG B1-25 "Advanced design of metal laminated coverings” the final brochure, by Pierre Mirebeau, Nexans (France)
    Due to environmental restrictions, advanced laminate coverings are now preferred to lead sheath to cover High Voltage extruded cables. The WG B1-25 has taken profit of an operation survey in 13 countries to establish a recommendation for tests and a guide to use these advanced laminate coverings, where several layers of plain (not corrugated) metal and plastic materials are bonded together to get a special set of properties. It replaces Electra 141 (1992).
  • 10:00 – 10:30 AM – “HVDC cable systems with particular reference to terrestrial applications”, by Ernesto Zaccone, Prysmian (Italy)
    The Increase of need for energy exchange across countries and the imperative mandate of the best exploitation of the available power resources, require a strong implementation of the transmission grids. Connection of remote generation plants to large consumption centers, has been facilitate by the realization of long HVDC links associated with latest developments in converters' technology. The consequence is a boost in the use of HVDC underground and submarine cables. So far, cables have been used for submarine applications while the tendency for land portions was to employ overhead lines. Recent technological developments in extruded DC cables increased also their use for land applications. Presentation will deal with technological aspects and will describe some projects currently under construction in Europe including Inelfe 320 kV (a full-land connection to transmit 2000 MW between Spain and France), Borwin2 300 kV (delivering 800 MW wind-generated power from 125 km offshore to 75 km inland), Skagerragk 4 a monopole 500 kV, 715 MW circuit connecting Denmark to Norway having 137 km submarine and 92+12 km of land cable being the latest one of the longest HVDC underground portion of the world.
  • 10:30 – 11:00 AM Update on Cigre WG B1.27 – “Recommendations for testing of long AC submarine cables for extruded insulation for system voltage above 30 (36) to 500 (550) kV” by Johan Karlstrand, ABB (Sweden)
    After almost 4 years of time, the WG B1.27 will now finish their work on testing recommendations for ac extruded submarine cables (36 - 550 kV). The Electra 189 recommendation will be replaced by the coming issue of the new TB, but the scope is wider and take into account even EHV cables as well as a more stringent approach to production quality and assurance. Furthermore, PQ- testing has been included in the overall scope. A brief update of the work of the WG will be presented.
  • 11:00 – 11:20 AM - Break. o 11:20 – 11:50 AM – “Pacific Gas & Electric Company Downtown San Francisco 115kV Underground Transmission Re-Cable Project A Unique Application of Existing Technology” by John Rector, Black & Veatch Corporation, and Albert Kong, Pacific Gas and Electric Company

  • 9:00 – 9:30 “Bioplasticized PVC for Wire and Cable Applications”, Bret Neese, Bharat I. Chaudhary, Robert Eaton, A. Ghosh-Dastidar, Wire and Cable R&D, The Dow Chemical Company. Abstract- Flexible PVC compounds are widely used to make the jackets and insulations of various wire and cable constructions. The incumbent PVC compounds are made using petroleum-derived plasticizers such as phthalates, trimellitates and mixtures thereof. Recently, bio-based plasticizers derived from renewable resources have been introduced to the market which, when substituted for the conventional plasticizers, can enable cable-makers and original equipment manufacturers to significantly reduce greenhouse gas emissions and eliminate the use of phthalates in their systems. This presentation will describe the characteristics of these bioplasticizers, as well as the properties of representative jacket and insulation compositions made with these bioplasticizers. The critical product properties will be compared with those obtained with traditional petroleum-derived plasticizers.

  • 2:00 - 2:10 PM - Subcommittee & Working Group Business
  • 2:10 - 2:35 PM - EVALUATION OF PD MEASUREMENTS ON MV CABLE SYSTEMS BY MEANS OF A WEB DATABASE by Frank Petzold SEBA kmt Germany
    The use of onsite PD measuring systems is more and more common to detect and locate PD faults to prevent service failures and loss of power supply.
    To perform a PD measurement is quite easy, but the interpretation of the results rises often more questions and makes the decision for replace or repair difficult.
    The increasing number of joint failures prepared in the past 15 years was an initial point to establish in Germany a VDE-working group to collect and share experiences of onsite PD measurements.
    More than 30 German utilities and several manufactures of pd measuring equipment are members of the working group.
    The outcome of this work is a WEB database, to collect in a clear structure the most important pd parameter of field measurements and the results of visual inspections of the located pd faults.
    The contribution describes the database in detail and presents that the evaluation of pd measurements and severity estimation of the specific pd fault has to be done under consideration of the type of accessory and also the nature of the defect.
    Because the ignition of PD in a defect depends from the type of excitation voltage the database is structured accordingly.
    The data collection in the database should be not limited on German utility and industry networks, but can be also used for worldwide input and use for interpretation of onsite pd measurements.
  • 2:35 - 3:00 PM - Sensitivity of the Hot Oil Moisture Assessment for PILC Cables to Field Test Conditions Joshua Perkel NEETRAC
    Although PILC cables are often regarded as a mature cable technology, they continue to represent a very significant proportion of the installed and network cable technologies. As a consequence most utilities need to maintain and support them. Most of the repair / replace decisions are determined by the level of moisture within the paper oil insulation system as this drives many of the degradation mechanisms. The most common approach is the “hot oil test”; where samples of tapes are immersed in hot oil and the liberated moisture forms a “foam”. However some of the NEETRAC utility members were concerned that the results could be affected by test conditions (oil temperature, sample length and time of test) and inconsistencies in interpretation of the degree of foaming. As a consequence NEETRAC undertook a series of designed experiments using PILC cables returned from the field to determine the effect of the test factors.
    This presentation will describe the methodology, document the significance and magnitude of the test parameters. The level of moisture within the tapes was correlated with the qualitative descriptions of foaming. Establishing critical levels for moisture content within PILC cables of different voltages is outside the scope of this presentation.
  • 3:00 - 3:25 PM - Utility Experience With VLF Withstand And Dielectric Loss Tests In Cincinnati Chris Fletcher Duke Energy
    Abstract: In 2005 Duke Energy began to investigate the potential benefits of cable diagnostic testing through participation in the Cable Diagnostic Focused Initiative (CDFI). Field testing in 2006 to the present, as part of the CDFI and by Duke personnel, has provided further evidence that cable system diagnostics could help the Company to improve service reliability and to maximize the value of cable system replacement budgets. The testing involved in these programs included Dielectric Loss, Monitored Withstand, Partial Discharge and Simple Withstand approaches.
    Many positive results from these trials led Duke Energy to implement a medium voltage underground cable system diagnostic program in 2008. The program presently involves the use of Time Domain Reflectometry, Dissipation Factor (Tan Delta) Measurement, and Very Low Frequency Withstand. This program continues to demonstrate the value of cable system diagnostics by prioritizing cable replacements, identifying cable segments that do not need to be replaced, and identifying cable and cable accessories that were about to fail while in service.
    The cable system diagnostic programs are underway in three different regions. This presentation will discuss some of the experience that the Duke Energy has gained with its cable system diagnostic program. The talk will also identify some of the benefits that have been received.

  • 3:40 - 4:05 PM - ASSESSING THE INTEGRITY AND INCREASING THE SERVICE LIFE OF HPFF PIPE TYPE CABLES Hank Kleinfelder Mears Group, Quanta Integrity Solutions
    Abstract: Electric utilities in the United States are currently utilizing over 4000 miles of high pressure fluid filled (HPFF) underground transmission lines. Most have been in service in excess of their 30 year design life with some being in service as long as 60 years. The systems have proven to be robust with very few problems and have required little or no maintenance. Over the years the pipe type cables have increased in their importance as part of the backbone of the transmission systems. As the systems continue to age new strategies need to be utilized to insure their ability to provide safe and reliable service. The following is a well established integrity program designed to assist asset managers properly maintain aging pipe type cables.
  • 4:05 - 4:30 PM - APPLICATION OF DISSIPATION FACTOR MEASUREMENTS FOR LIFE CONSUMPTION AND FUTURE LIFE ESTIMATION MODELING OF OIL-IMPREGNATED PAPER INSULATION IN HV POWER CABLES by Ed Gulski, onsite.hv.solutions AG, Switzerland Lukasz Chmura, Huifei Jin, Delft University of Technology, The Netherlands Frank de Vries, Alliander, The Netherlands
    This contribution gives the information about application of dielectric loss measurements for life consumption and future life estimation of oil-impregnated paper insulated cable. This is done by combination of laboratory experiment and on-site diagnostics. During laboratory experiment dielectric loss values were investigated at different temperatures and different electrical field intensities for samples characterized by different life consumption. Based on laboratory measurements, a program was built; it can calculate the life consumption of paper oil-impregnated insulation by on-site dielectric loss measurements. Future life estimation is calculated based on the result of life consumption and thermal aging theory in the program. Using field examples the of this method to qualify the degradation of oil-impregnated paper insulated cable, estimate the effect of operational history of the cable and support the future decisions of load profile and expected life of the cable will be discussed.
  • 4:30 – 4:55 PM -  DIAGNOSTIC OF INSULATION AGED IN DRY ENVIRONMENT by Bogdan Fryszczyn, CTL
    Recently CTL analyzed two 5 kV shielded EPR (pink and black) insulated cables, removed from service after approximately 30 years. The cables were removed because they failed field-testing criteria. Both cables operated in a dry environment. Results of both field testing and laboratory testing will be discussed.
  • 4:55 – 5:20 PM - Effect of Water Ingress on Dielectric Properties of Miniature Cables Made of Polyethylene Based Insulation with and without Electrical Stress by J-F. Drapeau and S. Bernier, IREQ
    This presentation reports on dielectric loss and dielectric strength measurements carried out on miniature PE cables immersed in water without voltage (hydrated) and under 5 kVrms voltage (aged). The dielectric losses were primarily measured using Time Domain Spectroscopy (TDS), allowing to obtain loss values in polarization and in depolarization, and also using VLF Tan delta (sine wave). Then, ACBD tests were performed to assess the dielectric strength of the miniature cable samples under the conditions: new, “hydrated” and “aged”. Results from this study are presented and discussed in terms of their possible implications on dielectric loss diagnostic interpretation.
