• Subcommittee A - Cable Construction and Design - Tuesday, May 4th, 2004, 2:00 – 5:30 PM
  • 2:00 - 2:20 - Subcommittee Business: Announcements
    Serge Pélissou, Hydro-Québec (IREQ) - Chair John Smith III, General Cable – Vice-Chair 
  • 2:20 - 2:40 – Carbon Blacks for Semicon Cable Compounds - Characterization Techniques and Impact on Cable Compounds
    Nicolas Probst, Eusebiu Grivei, Christine Van Bellingen, Timcal
    Abstract: Conductive carbon blacks for semicon compounds for cable applications will be discussed. The most recent analytical methods will be considered to assess the chemical and physical nature of these materials in view of their capability to predict the performance in a semicon compound. Carbon blacks produced with the furnace process, the acetylene black process and the MMM-process (Timcal) will be analyzed. The paper will also consider some practical processing aspects. 
  • 2:40 - 3:00 –  New Conventional Conductor Shield Technology
    S. Joon Han, Larry Gross, John Lastovica III, The Dow Chemical Company
    Abstract: New polymer technologies have been developed for application in semiconductive conductor shield compounds.  These technologies offer several advantages for conductor shields relative to the traditional polyethylene copolymers of alkyl-acrylate, or vinyl-acetate, that have been in commercial use for over 30 years. New semiconductive conductor shield compounds have been tested extensively both in the laboratory and on insulated power cables.  In this paper, the material characteristics and cable performance will be discussed.
  • 3:00 - 3:20 –  A Water Treeing Model
    Jean-Pierre Crine, Consultant; Jinder Jow, The Dow Chemical Company
    Abstract:  A new model for water treeing is introduced. It assumes that when the field-induced stress applied on nanocavities filled with a liquid is larger than the yield strength of the polymer, bonds will be broken and the nanocavity will expand. The growth of the water trees is enhanced by the fatigue induced by the alternating electric field. The diffusion of the liquid is also a parameter affecting the water-tree length. A simple equation relating the water-tree length with field, time, frequency and the nature of the solution is presented. A very good agreement between theory and experiments for a wide variety of results obtained with LDPE tested under various fields, frequencies and ionic solutions is observed. The model predicts the growth of water trees under dc fields after very long times or after many polarity reversals.

  • 3:20 - 3:40 – Break 

  • 3:40 - 4:00 – Advances in Moisture Cure Technology for Low Voltage Cable Applications
    Y. Gau, K.T. Devlin, D.P. Wright, M.B. Biscoglio, The Dow Chemical Company
    Abstract:  Cable manufacturers have used crosslinked polyethylene insulation to achieve superior toughness and high temperature deformation resistance on their cables since the 1960’s. There are several techniques used to crosslink polyethylene for low voltage (LV) applications. One of the popular approaches to crosslink LV insulation uses moisture curable crosslinkable polyethylene compounds based on ethylene-silane copolymers. This type of base resin is combined with a catalyst masterbatch during processing and is extruded as thermoplastic insulation.  The extruded insulation is subsequently crosslinked at elevated temperatures in the range of 80 to 90°C in a sauna or water bath for between 8 and 16 hours. Recent advances in catalyst technologies have shortened this curing time significantly, and have made curing under ambient conditions practical and feasible. This paper describes the development of a faster curing catalyst and the scorch retardant technology to prevent premature crosslinking (scorch) during processing. Data on scorch and rate of crosslinking are presented. Compatibility of the catalyst with flame retardant additives is also discussed. In addition to having a faster cure rate, the newly developed compounds retain all the advantages offered by moisture crosslinkable ethylene silane copolymers, which have been in the marketplace since the 1980s. They do not require reactive compounding to make Sioplas copolymers, there is no handling of liquids as in the Monosil process, and they essentially have no residual unreacted monomer.

  • 4:00 - 4:20 – Influence of Corroded Conductor on the Performance of Medium Voltage Extruded Cables
    S. Pélissou, J. Côté, R. Savage, S. St-Antoine, Hydro-Québec
    Abstract:  This paper presents the results of the characterization of medium-voltage extruded cables, with a corroded aluminum conductor and aged under various simulated field conditions. The goal is to determine whether "milky" water found in the conductor strands or the corrosion left on the conductor surface affect the performance of the cable. The field-aged cables, 28 kV class and XLPE insulated, were further aged under four conditions for the inner conductor: with and without water, with an aqueous solution, and with silicone. The results indicate that the presence of water and corroded aluminum in the conductor strands decreases cable performance. Furthermore, it is found that silicone-injected cable samples have in their insulation the least amount of water and the least number of and smallest water trees, along with the greatest AC breakdown strength.

  • 4:20 - 4:40 – 69 kV Pipe-Type Retrofit XLPE Cable Design
    Thomas Wilki, Forte Power Systems
    Abstract: When utilities have to replace aging pipe type cables with XLPE cables, a special design is required to meet the challenges of the existing pipe installation. This presentation provides an example of such a cable design provided to a major US utility for installation within a 5 inch steel pipe. This 69 kV cable features a 1000 kcmil conductor with reduced insulation wall and LC shield. Dimensions, electrical stress, ampacity and jamming ratio will be discussed.

  • 4:40 – 5:00 – 230kV XLPE Underground Cable Line Crossing the Mississippi River
    Paul Zimmermann, Entergy; Shinya Asai, Kenichiro Tanimoto, J-Power Systems
    Abstract: 230kV XLPE cables are installed crossing the Mississippi River using HDD technology. Cables with a conductor of 2500mm2 with insulated wires are applied for this project was the first time this application was utilized in U.S.A. The project background and the design of the line will be introduced.

  • 5:00 – 5:15 – Meeting Adjourn
    Serge Pélissou, John Smith III

• Subcommittee B - Accessories 
  • Development of EHV Class Cold Shrinkable Joint
    Hideo Tanaka (VISCAS Corporation, Japan)
    Abstract: Cold shrinkable joint is one of the most advanced joint for HV XLPE cable. This joint is made of silicone rubber and its installation on site is very easy and simple because of excellent elastic property of silicone rubber. The basic design concept of this new joint, its field experiences at 110-138kV class line, development of 275-400kV class application and its future application will be described.
  • Conditions Assessment of a 42-Year Old 230kV Self-Contained Fluid-Filled Cable at BC Hydro
    Dr. S. Cherukupalli, T Kojima, BC Hydro Engineering
    Abstract: This work describes the process followed to evaluate the condition of a 42- year old 230kV SCFF cable system, determine whether the cable system requires replacement or upgrading, and to identify opportunities for uprating. This circuit’s reliability was considered to be very critical during a second contingency situation, when the existing steady-state current ratings can be exceeded. Also the cable system was commissioned in 1962 and is approaching the end of its 40-year economic life. This presentation covers the first phase of the investigation, which examined the operating characteristics of the cable system, reviewed the maintenance records, and developed the project plan. Results from distributed fiber optic temperature measurement to uncover potential hot spots, systematic gas-in-oil analyses, and sheath-bonding changes are also presented. Systematic gas-in-oil levels exhibited disconcerting levels of H2, C2H2 as well as, high oil power factors.
    
    The presentation covers some of the redemption measures adopted to rejuvenate cable splices and the results from these findings. It is hoped that this will stimulate some debate on the relevance of prescribed gas levels and degree of concern as stated in present IEEE Standard Guide.1406- 1996. This will be of particular relevance as BC Hydro is currently operating cable systems at levels higher than those prescribed in this Guide.
  • Panel Session - Experiences with the Impact of Weathering on Polymeric & Elastomeric Materials used for Electrical Applications in Outdoor Environments
    Moderator: Wolfgang Havercamp, Raychem Corporation
    Panelists:
    • Ravi Gorur, Arizona State University, Professor, Electrical & Computer Engineering
      Laboratory Testing to Simulate Field Conditions in Aging of Polymers
      Summary: Field aging processes occur gradually over many years. Laboratory efforts to simulate and accelerated field aging processes can produce a mixed and sometimes unrealistic results. The aging of polymeric materials is a complicated process that involves many variables. Some materials exhibit recovery characteristics that allow the material properties to improve if exposure to detrimental agents is reduced. Also, the level and length of exposure to a detrimental agent can change the aging properties and the level of damage developed within a material.
    • Dave Thornley, Tyco Electronics, Raychem
      Mechanisms of Deterioration in Polymers and Some Examples
      Summary: The various deterioration mechanisms in polymeric cable accessories will be discussed and some associated field failures will be presented. Deterioration mechanisms considered include: tracking, erosion, UV exposure, water uptake, etc.

• Subcommittee C - Cable Systems
  • Overview of Highly Accurate Fault Locator on Transmission Lines
    Kazuo Amano, Fujikura
    Abstract: Accurate localization of faults on power transmission lines is very important to save time and resources for the electric utility industry. Thus, we have developed a highly accurate fault locator which is based on the traveling wave method. Our new fault locator uses precise pulse signals from the GPS satellites to synchronize the clocks in each local station of the line ends. On field tests of transmission lines 33 - 500 kV, it was confirmed that the location accuracy is +/- 10 - 40 meters, independent of line length. To achieve this accuracy, our fault locator is equipped with a high-resolution timing counter and installed with a unique algorithm on compensation for distorted traveling waveforms. We will report an overview of our fault locator and location techniques for HV and EHV transmission lines.

  • San Diego Bay Cable Replacement Project
    James Carr, San Diego Gas and Electric
    Abstract: The San Diego Gas & Electric Company recently relocated a 69-kV transmission line under the San Diego Bay. This important transmission line serves the City of Coronado and North Island Naval Station. The existing cables will be removed in preparation for dredging of the shipping channel in the bay. Two directional drills were performed from the Embarcadero in downtown San Diego to Coronado, a distance of approximately 3,100 feet. Each crossing contains four HDPE conduits to provide capacity for two transmission circuits and one distribution circuit. Cable design for this project was very important to allow the very long cable runs to be transported over land, while also meeting reliability and ampacity requirements for this project.
  • Toluca-Van Nuys Line D, 230-kV Project
    Hassan Motallebi, Los Angeles Dept. of Water and Power (LADWP)
    Abstract - This transmission line is 5.6 circuit miles long and consists of 90,000 feet of 230-kV XLPE cable, 69 joints, and 6 terminations. A duct and maintenance hole system was used to construct this line. Twenty-three maintenance holes connect LADWP's Toluca Lake receiving station to Van Nuys receiving station. Cable sheaths were bonded using cross bonding method. Embedded optical fibers provide for temperature monitoring of the line. This line provides an additional transmission capacity of 160 MW for LADWP. The construction of this line took approximately two years to complete.

  • Partial Discharge Test Results
    Matt Mashikian, Imcorp.
    Abstract - Snap-shot statistical data about the service performance of two different populations of service-aged cables will be provided. The two populations are: (a) cable feeders deemed by PD testing to be serviceable; (b) cable feeders classified by PD testing to be defective and unreliable. The presentation will specifically provide information on the survival time in service from the initial discovery of PD activity. Dissection of a number of surviving PD sites will shed much needed information on the nature of defects generating PD and the possible mechanisms controlling their growth rates.
  • Silicon Injection of Power Cables in Canada
    Richard Riley, Transle/Common Inc of Canada
    Abstract - Medium and high voltage solid dielectric cables installed prior to 1980 have experienced significant degradation in dielectric performance and reliability. While modern cables are likely to maintain their performance for much longer, the older vintages are now a cause of concern. Since 2001, we have been involved with the technology of silicon injection. This technique improves the dielectric strength of most solid dielectric power cables and significantly increases their life expectancy. This paper discusses the statistical results of cable injections done in Canada over the past three years. We will also list the most common business and technical factors that have influenced utilities in using this technology.

  • 10:15 - 10:30 - Coffee Break
  • 10:30 - 10:50 - High Frequency Attenuating Cable for Protection of Low-Voltage AC Motors Fed by PWM Inverters
    Liming Zhou, DTE and Steven A. Boggs, UCONN
    Abstract: Variable or adjustable speed drives generate pulse width modulated waveforms with rise times below 100 ns. These very rapid transitions can cause large turn-to-turn voltages in inductive devices such as random wound motors, resulting in partial discharge and premature failure. One way to mitigate this problem is to absorb high frequency energy in the cable between the drive electronics and the motor. This contribution analyzes design considerations for optimization of such a cable.
  • 10:50 - 11:10 - The Effect of Conduit Fill on Premises Cabling
    John Fee, American Polywater
    Abstract: Optimizing the fit of premises cable into conduit is an important issue of cost efficiency. Information on the effects of higher conduit fill levels is of interest to current standards developers. This paper looks at physical limits for installing cable at higher conduit fill levels.
  • 11:10 - 11:50 - 2004 Revision to IEEE 690
    John Merando, Bechtel and Malcolm Thaden, PEPCO
    Abstract: The “Standard for the Design and Installation of Cable Systems for Class 1E Circuits in Nuclear Power Generating Stations”, IEEE 690, was originally issued in 1984 and has been re-affirmed once without revision. The standard has served the industry well for twenty years. Now there is a potential for new nuclear plants to be designed and built within the next five to ten years. Members of nuclear power industry, IEEE Energy Development and Power Generation Committee, and other interested parties felt that it was time to re-examine standards related to nuclear power plants and revise as needed. The guidance and detail provided in IEEE 690-1984, when originally issued, was necessary and appropriate as at that time few other IEEE standards discussed and provided guidance on this subject. Now there are numerous standards available that provide information and guidance on various aspects of cable design and installation. Additionally, much has been learned about good and bad installation practices. This presentation will review the changes to IEEE 690-2004.

  • Laying, Installation and Commissioning of a 400 kV Cable System in JUTLAND (Denmark)
    Pierre Argaut, Sagem
    Abstract: In order to get the permission to build the 400 kV transmission Line between Aarhus and Aalborg the western Danish transmission system Operator Eltra had to accept the use of underground cables on three short sections of the line. The cable system dimensioning has been made in order to match the ampacity of the line, during a short time period of extra load of the cable without overloading it. Different measures have been taken to minimize the impact on the environment of the underground sections: both cable and joints are direct buried and the native soil is used for backfilling. Commissioning tests are carried out at the highest voltage level prescribed by IEC 62067 and for a duration higher that the duration prescribed by the Standard. Due the voltage applied, and to the length of the tested circuits, the test equipments of two external laboratories have been necessary to supply the requested power. Two of the three sections have already been tested without problem. The third one will be achieved and tested at the beginning of summer 2004.
