• Subcommittee A - Cable Construction and Design, Tuesday April 5, 2016 - 8:00 AM - 12:00 PM
• Experiences of Combined HV & EHV Cable Qualifications to IEC, AEIC and the Challenges of adding IEEE 48 or 404 by Caryn M. Riley, Josh Perkel, Raymond C. Hill, and R. Nigel Hampton NEETRAC, Atlanta, USA, caryn.riley@neetrac.gatech.edu, joshua.perkel@neetrac.gatech.edu, ray.hill@neetrac.gatech.edu, nigel.hampton@neetrac.gatech.edu
  Abstract - Cable Qualifications combining the elements of AEIC and IEC can be made with sufficient care. These are always system tests as even if the cable qualification is desired, suitably robust terminations are required. There are increased risks, but experience shows that they can be managed. This paper focuses on the issues associated with taking an existing Cable Qualification (as a system) and then bringing one or more of the IEEE cable accessory standards into the AEIC / IEC combination approach for cable system qualification. It first highlights the similarities and differences associated with the testing methods, test limits, and number of components/lengths of cable required by each standard.  NEETRAC’s experience with the AEIC / IEC combination approach from 2005 – 2014 is then reviewed with respect to the overall failure rate of each component type.  Finally, the risks / benefits of combined qualification programs containing either complex test loops (i.e. number of components) and / or combined standards requirements is presented.
• High quality carbon black to surpass traditional solution for HV semicons? Daniele Bonacchi (1), Christine Van Bellingen (1), Denis Labbé (2) 1 – IMERYS Graphite & Carbon, Bodio, Switzerland, daniele.bonacchi@imerys.com, christine.vanbellingen@imerys.com 2 – P&M Cable Consulting LLC, Geneva, Switzerland, dlabbe@pm-ch.com  
  Abstract - The efficiency of the semiconductive layer depends on its electrical conductivity that is guaranteed by the presence of conductive carbon black in the semicon formulation. It has been proven that electrical aging mechanisms are directly linked to semicon protrusion as they locally increase the electrical field.
  
  Fig. 1: Conductive carbon black TEM picture
  As carbon black is an essential constituent of semicon compound, its quality affects the semicon performance and hence the final cable lifetime. Any impurities present in the raw material such as grit (e.g. large amorphous carbon particles remaining from production) or carbon black agglomerates not to mention ionic content are detrimental for the final application. While the level of grits is an intrinsic characteristic of the carbon black used and will remain in the final compound, the carbon black agglomerates must be dispersed and distributed by proper processing although only specifically designed carbon blacks can achieve high level of dispersion. For example low surface area is linked to large primary particles and is known to favor dispersion thanks to the better wetting of the aggregates by the molten polymer. Also the high carbon black structure (e.g. a high degree of branching of the carbon black aggregates) is known to ease dispersion and distribution thanks to the lower inter-aggregate interactions and that is why low surface area high structure carbon black are the only choice for HV and EHV semicon compounds. Although surface smoothness is the primary requisite for a good semiconductive compound, other characteristics are essential for a good quality HV cable. A proper level of volume resistivity at the operating cable temperature and its stability after thermal cycling is also crucial for good cable manufacturing. Proper level of conductivity is achieved only at specific carbon black loading that is in turn dependent mainly on the level of branching or “structure” of the carbon black aggregates and the intrinsic carbon black conductivity. In this presentation we will show that an easy-dispersible, clean carbon black, with higher intrinsic conductivity can be used at lower loadings than the commonly used carbon black in HV semicons. By direct comparison we will show the benefits of using lower amount of the new carbon black, especially the lower viscosity and the longer scorch time of the compound while keeping excellent surface smoothness and stable conductivity. Carbon black ionic impurities and moisture uptake that are transmitted to the final compound and can initiate electrical treeing will also be discussed in detail.  
• Thermo-Mechanical Failure of 345 HPFF Paper-Insulated Pipe-Type Cable by Carlos Katz & Vitaliy Yaroslavskiy of Cable Technology Laboratories and Arnold Wong of Consolidated Edison Co. of NY  
  A step-by-step investigation and analysis of the failure of a 345 kV High Pressure Fluid Filled (HPFF) Pipe-Type cable, 37 years in service will be provided.  This cable was insulated with oil-impregnated cellulose paper.  The pipe and three phase cable, in the area of the failure, were made available.  It was discovered that the paper insulation had been embrittled, apparently, during drying in the cable manufacturing process.  Repetitive snaking of the cable during routine load cycling caused movement of the paper insulating tapes, resulting in soft spots, including numerous tape registrations that weakened the cable insulation structure and ultimately precipitated the cable breakdown.  In spite of the mechanical weakness, electrical tests on the insulating tapes point to significant retention of original properties.
• Qualification of cables and cables systems with new EHV accessories for land power transmission – Pierre Mirebeau – Nexans
• Subcommittee B - Accessories, Tuesday April 5, 2016 - 2:00 PM - 5:30 PM
  • Suggested Changes to Distribution Joint Standard B22W, IEEE 404 Distribution, Glenn Luzzi – Richards-MFG
    Since the first edition of IEEE 404-1977 there has been a requirement that cable joints must operate at the same maximum temperature limitations as those of the cable being joined. However, there has never been a performance test specified to ensure this criterion is being met. This presentation suggests several changes for the future “distribution” joint portion of the standard being developed in B22W. It describes both a performance test as well as criterion for assessing joint operating temperature capability. It further proposes a Class 1, 2 or 3 joint based on the test results.

  • 9:30 AM - 10:00 AM “Mackinaw Straits Submarine Cable Termination Replacement” by Ken Jauquet, American Transmission Company, Ron Knapwurst, American Transmission company, John Rector, Black & Veatch.
    The Mackinac 138 kV Submarine cables, installed in 1975, cross the Straits of Mackinac and connect the lower and upper peninsula of Michigan. On the north side of Lake Michigan, they connect to a new HVDC Back to Back Converter Station.  These cables began experiencing leaks near at their terminations in the last years. The leaks persisted and became worse, even after numerous repairs had been made. The American Transmission Company (ATC) decided the time was right to replace the terminators and sections of the shore-end cables on each side of the crossing. The cables were successfully repaired, but not without some very tense moments. This presentation describes the unexpected challenges we found and the time critical constraints we had to work under.

    Abstract—Transients and repetitive transients affect cable insulation life in a waywhich is not easily predictable at the design stage. Therefore, cable system life can be shorter than that expected especially when loads controlled by power electronics are fed, or when HVDC systems are integrated in AC networks. This paper has the purpose to provide a statistical approach to estimate the life of a cable insulation system when repetitive transients, of know probability distribution, are expected to affect insulation during operation. It is shown, using the Miner law and a stochastic approach, that life at a given reliability percentage can be shortened even significantly, depending on transient overvoltage and repetition rate. Condition monitoring, however, remains the main tool to keep track of cable heath condition during operation life

  • 3:35 PM – 4:05 PM:  “Preliminary on-site classification of MV cables by using a simple DC insulation tester”, Sverre Hvidsten, Sintif – NORWAY.
    Condition assessment of water treeing in medium voltage XLPE cable insulations by tan δ measurements is well established. However, the interpretation of the measurements can be difficult and even wrong if the cable section has one or more joints with a low insulation resistance, as the tan δ can be significantly higher for the joints than for the cable insulation. This presentation describes a simple method based on using an insulation tester to reveal if joints with low resistance are present in the cable link. Measurements have been performed on cable samples with joints taken from service after more than 20 years due to high tan δ values and partial discharges located in the cable. The joints were characterized in the laboratory by time domain dielectric response and dielectric spectroscopy. It has been shown that both the polarization and depolarization currents should be used during the assessment to provide robust evaluation criteria to distinguish the response of a low resistance joint from heavily water treed cable insulations avoiding misinterpretation of the cable condition. This method should be used before applying any other diagnostic equipment for such cables. In addition, the reproducibility of the measured currents has been evaluated by performing on-site measurements on different cable sections with actual joints. It is shown that both the polarization and depolarization currents remain approximately unchanged, indicating that robust criteria for cable condition assessment can be established. Finally, the cause for the high polarization currents (or low resistivity) of the joints is likely the combined action of water sorption and thermal ageing of the stress control sleeve.    
  • 4:05 PM – 4:35 PM  “Impact of non-linear grading material on cable diagnostic – measurement vs. simulations”, Boguslaw Bochenski, Kinectrics Inc - CANADA  
    Proper commissioning and condition assessment of MV and HV cables is primarily based on high voltage testing. Withstand testing using alternative voltage sources (i.e. VLF 0.1Hz or 0.01Hz, VLF Cosine-Rectangular, Damped AC) as opposed to power frequency test sources, can leave critical portions of the cable system such as field graded terminations and joints less severely tested, or tested in an entirely non-representative manner.  For example, the electrical field along the insulator surface in terminations and joints utilizing non-linear field grading materials is significantly lowered compared to power frequency stress in the critical ‘field limiting region’ around the semi-conductive screen cutback area. This not only results in a requirement for a differing withstand voltage requirement for alternative voltage sources compared to power frequency stresses to achieve the same electrical field in the termination, but also is one key explanation for differing PD Inception Voltage (PDIV) and Extinction (EV) voltages, in high field regions in non-linear graded accessories, when using alternative voltage sources. The presentation will discuss initial results from steady-state and transient finite-element based simulations that explain this issue, and proposed courses of action to mitigate against such issues in commissioning and diagnostic testing.
