This comparison was also made with previous ACLT (Accelerated Cable Life Test) results.
    • Fundamentals for Achieving Long Cable Life Series: Enhanced Overvoltage Protection for Reliability Beyond the First Decade by Wayne Chatterton and Ben Lanz, IMCORP
      Abstract: Adequate overvoltage protection is essential for long solid dielectric insulation service life.  Within the first few years of operation, the AC breakdown (ACBD) voltage of new cable insulation is quite high but typically drops within the first decade to a fraction of the original value. Overvoltage protection margin has traditionally been calculated on the basis of new cable basic impulse levels (BIL).  Thus, there is a significant opportunity to improve overvoltage protection by calculating margin using the typical BIL insulation will ultimately retain. A case study will be presented to show how a combination of improved overvoltage protection and the removal of discrete defects can significantly improve cable reliability and therefore extending its useful life for decades.
  • Subcommittee B – Accessories – Monday, May 7, 2018 2:00 PM – 5:30 PM

    • 2:15 PM – 2:30 PM Standards that need to be updated  – Stan Szyszko
    • 2:30 PM – 3:15 PM “Real-World Enclosure Temperatures” – James Steel , Novinium
      Circuit owners often monitor cable and transformer temperatures for critical transmission circuits, however, the temperatures that exist inside distribution-voltage electrical enclosures have not been well documented.  This presentation shares the survey results of temperatures recorded inside electrical enclosures throughout North America.  The results were collected over the course of a year on underground residential distribution (URD) systems ranging from 15 to 35kV and at four geographically distinct locations in cryic, mesic, thermic and hyperthermic soils.  This paper illustrates the effects that ambient conditions, seasonal load fluctuations and installation factors have on the temperatures measured inside enclosures.  It is well known that extreme temperatures impact the long-term functionality of cable accessories and equipment contained within distribution-class electrical enclosures. As a result, the corresponding standards and guides should be updated to accurately reflect the temperature ranges observed in this survey.
      James has over 16 years of experience with cable injection technology, designing and operating cable test equipment, on-line partial discharge measurement technology and mitigating manhole events (smoke, fires and explosions) caused by aged secondary network cables.  James is the inventor of 13 US patents and currently serves on the working groups for IEEE1617 – Guide for Assessment, Mitigation and Control of Corrosion on Metallic Shields in Extruded Dielectric Cables rated 5-46kV and IEEE 1511.2 Guide for Investigating and Analyzing Failures of Joints on Extruded Shielded Power Cables on Systems Rated 5 kV Through 46 kV.
    • 3:15 PM – 3:30 PM – Break
    • 3:30 PM – 4:15 PM – “Elbow IEEE Test Sampling Plan Improvement Proposal” – Tinghui Xin and Brian Ayres, TE Connectivity
      The goal of this work is to improve the elbow qualification test sampling plan by reducing the sample size and testing time while keeping the same statistical power.
      An easy-to-understand statistical model is derived in the presented work based on binomial distribution. A common mathematical reference is established as the connecting point between current sampling practice as described in IEEE-386-2016 clauses and the proposed sampling plan intended for better efficiency and statistical rigor. The flexibility of the model allows one to find the desired and reduced sample size based on targeted probability of passing a qualification test under an assumed product reliability. Further, it recommends that passing the first N consecutive samples as compared to current practice (loosely expressed as passing test until “N products in a row pass within a given number of samples”). The proposed sampling plan intends for higher stringency and better economy.
      This work is focused on a unit cell which is defined as a predetermined number of samples with one set of mating inserts. The result of the work is exhibited in contour plots and variability charts. The work can be easily extended into a series model that incorporate flexible configurations by combining various elbow manufacturers and mating inserts as well as switching operations.
    • 4:15 PM – 4:55 PM – “Progression of Faulted Circuit Indicator Technology“ –  Eugene Weaver, SEL
      Faulted circuit indicators (FCIs) are cable accessories that indicate the passage of fault current in insulated and uninsulated conductors. Like other distribution equipment, faulted circuit indicators (FCIs) have continued to evolve with distribution system operating practices. This has led to technological advancements in FCIs since their inception over 70 years ago. Recent advances within wireless sensor technology allow the distribution engineer to explore FCI applications in automation and distribution equipment protection.  This presentation briefly looks at the progression of FCI technology. It dives deeper into what FCIs can be used for given the current technological landscape.
      Eugene Weaver is the Product Manager for Faulted Circuit Indicators (FCIs) and Sensors at Schweitzer Engineering Labs Inc. (SEL). He joined SEL in 2007 as a Field Application Engineer and has had various roles contributing to the development and application of FCIs.  Eugene is presently the Chair of the B24W working group for the IEEE-495 guide for testing faulted circuit indicators.

    • 9:25 AM – 9:50 AM “Trials and Tribulations with a repair of a 230kV SCFF cable damaged by a dig-in,” by Sudhakar Cherukupalli and Karl Mai, BC Hydro
      This presentation will offer an overview of the some of the key considerations and issues that unfolded following an accidental dig-in by a third part into a 50 year old energized 230kV SCFF cable.  The presentation will address repair strategies considered, assessment of the insulation and insulating oil, treatment of the 50 year old spares, and how the work was completed and the cable energized successfully.  Lessons learned from this exercise will also be shared.
    • 9:50 AM – 10:15 AM “Brillouin-based Distributed Temperature Sensing (DTS) monitoring system for Submarine Export Cables of Off-Shore Wind Farms (Europe),” by Landry Molimbi, NKT Photonics
      The abstract will be the following: For high and extra-high voltage power cables, the maximum temperature of the insulation must never be exceeded at any location and under any load condition. The local temperatures depend not only on the cable design and load history, but also on the local thermal environment of the cable. Therefore, distributed temperature monitoring of high-/extra-high voltage cable systems is essential to ensure the integrity of the cable at high load. Especially, the load of the export cables of wind farms varies strongly in dependence on weather conditions. In this field study, we demonstrate the measurement performance of a new, robust Brillouin distributed temperature sensing system (Brillouin-DTS). The system is based on spontaneous Brillouin scattering and does not require a fiber loop. This is essential for long submarine high-voltage cables, where normally no loop can be formed in the seabed. It is completely passively cooled and does not contain any moving or wearing parts. The instrument is dedicated for use in industrial and other rough environments. With a measuring time below 10 min, the temperature resolution is better than 1 °C for distances up to 50 km. In the field study, the submarine export cable of an off-shore wind farm has been monitored. The temperature profile of the export cable shows several hot spots, mostly located at cable joints, and also several cold spots.
    • 10:15 AM – 10:30 AM – Break
    • 10:30 AM – 10:55 AM – “Manhole Explosions: Why they occur and how to prevent them” by Glen Bertini & Jason McCary, Novinium
      Manhole explosions are a nightmare for the public and manhole owners. Unpredictability, life-threatening potential, and the setting in crowded urban areas, make manhole explosion particularity pernicious. This presentation catalogs the fundamental causes of manhole fires and explosions in duct-manhole systems whether they are fueled with electrical energy, chemical energy, or both. In all urban areas where duct-manhole systems exist, there are complex interactions between the electrical cables and chemistry that happens inside and adjacent to manholes. This presentation focuses on the predominant causes so that resources can be intelligently focused to prevent explosions from occurring.
    • 10:55 AM – 11:20 AM – “Bergen Linden Corridor Program – 345 kV Newark Bay Crossing” by Dennis Johnson, POWER Engineers and Charley Patterson, Southeast Directional Drilling
      This presentation discusses the processes and challenges that were experiences during the drilling of two 6600 foot HDD drills and the associated installation of casing and conduit bundle.
    • 11:20 AM – 11:55 AM – “On-Site Acceptance Testing of Submarine Inter-Array Cables at Offshore Wind Farm” by Ed Gulski, Rogier Jongen, Onsite HV Solutions ag, Switzerland and Matthijs de Heus, Onsite HV Solutions Benelux, The Netherlands
      Systematic testing and diagnosis during manufacturing, transportation, installation and operation can exclude or at least reduce possible risks of a failure during operation. The 33 kV inter-array cables have been the standard to date, but slowly the 66 kV power cable as the standard solution will replace them. Considering the enhanced risks by using 66 kV cable systems advanced quality control is becoming very important. The main challenge will be the need of specialized teams for installation and advanced testing activities, where they will need to be carefully certified to work t a higher voltage level.  In this presentation, the aspects of present international regulation as well as the best practice will be discussed.
    • 11:55 AM – 12:15 PM – Chairman’s Closing Remarks
  • Subcommittee D – Generating Station and Industrial Cables – Tuesday, May 8, 2018 8:00 AM – 12:00 PM

    • 8:30 – 9:15am – “Dielectric Spectroscopy of Low Voltage Nuclear Power Plant Cables”, Drew Mantey, David Rouison, Sarajit Banerjee
      Abstract: Previous research has shown that applying a low voltage technique called dielectric spectroscopy (in the frequency and/or time domain) to cable insulation shows promise to provide a global evaluation of the cable dielectric capability. The test method applies voltage to the conductor and uses adjacent conductors or ground shield as the test signal return path.
      The present research applied low frequency dielectric spectroscopy (LFDS) methods to three different sample cables; two unshielded cables (3 conductor EPR insulation / CSPE jacket cable and a 3 conductor FR-XLPE insulation / CSPE jacket power cable) and one shielded cable (24 conductor CSPE-EPR composite insulation / CSPE jacket). The cables’ as found condition was evaluated by commonly used physical/chemical tests. Baseline LFDS and polarization / depolarization current (PDC) data was taken using various test configurations to identify the optimal test configurations for each cable. Samples were then subjected to laboratory accelerated thermal aging and retested to determine if electrical parameters tracked with physical/mechanical testing.  The sensitivity of measured LFDS and PDC data to varying experimental (non-aging related) parameters was assessed, including multi-conductor cable test configuration, measurement electrode grounding, external (mandrel) grounding, ambient temperature, applied test voltage level and various combinations. These were done to validate the efficacy of the test method and the optimal way to obtain test data in the field.

    • 9:10 AM – 9:50 AM: “Condition Assessment of Pipe-Type Joints Utilizing Limited-Angle Computed Tomography X-Ray Technology” by Arie Makovoz and Jade Wong of Consolidated Edison Co. of NY, and Stephen Halliwell of VJ Technologies Inc.
      Most of Con Edison’s 800 miles of underground transmission cables consist of High-Pressure Pipe-Type feeders.  Joints of these types of feeders can move over time and, therefore, must be inspected periodically for signs of damage or future failures.
      Two dimensional (2D) x-ray imaging of the underground transmission joints was done initially using Cobalt-60 radioactive isotope sources and film, but more recently the use of electrically generated high energy x-ray sources and digital imaging techniques has made this operation safer, faster and has provided higher fidelity images with significantly better contrast, resulting in improved analysis of the condition of the cable and joints. However, the images were still only two dimensional which meant that critical failure indications, which required immediate remedial action, may not be visible in the images due to the masking effect of materials in front of or behind the failure indication.
      The use of three dimensional (3D) imaging using computed tomography (CT) is an established technique used in medical and industrial applications to enable complete volumetric inspection.  Typical CT systems require 360º scanning of the object, but in the limited space around underground feeder cables this is not achievable.  In theory computed tomography is possible with less than 360º of scanning, based on which VJ Technologies and Consolidated Edison evaluated and validated this concept in the laboratory.  Following that exercise a proof of concept field inspection system was built and tested, then then a fully field deployable Limited-Angle computed tomography system was built and tested.This paper describes the process from concept validation in the laboratory to the testing of a fully engineered field deployable system on a feeder cable joint.

    • 10:15 AM – 10:40 AM: “Overseas Experience With Damped Ac Diagnostics For Aged High-Pressure Fluid Filled Cable Systems” By Paul Leufkens, Power Projects
      High-Pressure Fluid Filled (HPFF) cable systems are used downtown or in other critical environment and where they can transmit large power as they are so compact. These pipe-type cables have been used since the sixties which makes that challenges come up with possible ageing of the insulation due to high thermal loads, over the whole length or in particular parts that were buried with less cooling.  Corrosion and or leakage occurs after age or due to damage from outside.
      Proper Asset Management needs reliable information about remaining life time in order to make the right decisions whether parts or whole circuits have to be replaced and if so, which are the most critical. After this the question comes up how to replace the cables, with limited production capacity of HPFF cables left.
      Against this background the presentation will highlight overseas experiences with field testing on aged pipe-type cable systems and the strategy of TenneT, the TSO of Netherlands, how to improve reliability and upgrade their network of high pressure gas filled pipe type by selective replacement.
      The Damped AC diagnosis is shown to be effective as it applies AC voltage without much breakdown risks of healthy insulation, and measures tan  and partial discharge over the full circuit length and can interpret them as function of the location. We will show examples of Damped AC diagnostics, with different stages of aging and dedicated conclusions
      As existing 123 and 170 kV Gas Pressured Pipe Type cable circuits typically have a long repair time they are the first to be investigated with diagnostic tests in order to enable decisions based on urgency. Damped AC is chosen by TenneT to select between suspect circuits while shorten outage periods for testing. A new XLPE-in-pipe refurbishment solution is presented which can work at high electric stresses keeping the pipe diameter comparably small.
      As follow-up a survey is designed to systematically collect North American experiences and possibly an expert user group will be set-up to exchange best practices.
    • 10:45 AM – 11:15 AM:  “AC and PD Commissioning Testing of 10 Mile Long 345 kV XLPE Underground Transmission Circuit “, by Alfred Mendelsohn, Power Delivery Solutions, Inc. and Lorenzo Paschini, Techimp HQ Srl
      This presentation will review the technical challenges in the AC and PD commissioning testing of a large 345 kV XLPE project consisting of 5 separate underground 345 kV XLPE circuits with a combined total length of about 22.5 circuit miles. The longest of the circuits is approximately 10 miles long, with 2 outdoor terminations and 22 joints on each phase.
      The commissioning testing requirements for the project consisted of an AC Hipot test at 339 kV (1.7 U0) for 1 hour with simultaneous PD testing of all joints and terminations. To be able to perform the AC test, it was necessary to use 4 large 260 kV RTS units, 2 in series coupled in parallel with another 2 in series. This represented the first time in North America that a series/parallel combination of 4 RTS units were required for the AC Hipot test on a 345 kV circuit. The only previous time such a setup was required was for the AC and PD commissioning testing of a long 500 kV circuit in 2016.
      This presentation will review the complex setup of the 4 RTS units, as well as the elements of the preinstalled PD systems in all manholes and at terminations used for the PD commissioning tests. Sixteen (16) of the joints were segmented joints, while six (6) of the joints in the circuit were straight joints. For the segmented joints, clamp HFCT (high frequency current transformer) sensors were used, while for the straight joints magnetic coupling sensors were placed on the joint bodies. The test conditions and the key test results from the commissioning testing will be presented.
      The testing of the longest circuit was completed in early March 2018 and the circuit was energized in mid-March 2018.
    • 11:20AM – 11:50AM “Characterization of Dielectric Loss Using Time Domain Spectroscopy (TDS) :  What Have We Learned Over 14 Years of Cumulative Testing Experience ?”, Jean-Francois Drapeau, IREQ, (Hydro Quebec Research Institute), Canada
      Dielectric loss measurement, as a testing approach for performing condition assessment of underground cable systems, poses a number of challenges in terms of interpretation of the results data, related to the fact that it constitutes a “global” measurement. Indeed, the dielectric loss measured on a whole cable system is the result of the summation of all the specific loss contributions of each individual component (various pieces of cables, plus a number of accessories constituted of joints and terminations) averaged over the total direct capacitance of the cable system. With the current tools and diagnostic features available, the use of dielectric loss measurements does not allow yet to discriminate between the various types of degradation that may be present. Compared to the classical diagnostic based on measurement of VLF Tan Delta (typically at 0.1 Hz), experience with dielectric spectroscopy has shown the potential to bring more interpretive information’s. This presentation will discuss the specific application of Time Domain Spectroscopy (TDS), which is based on measurements performed with DC voltage application. The topics addressed in this presentation will include: a theoretical review of the constitutive elements of dielectric loss, a preliminary comparison with frequency domain spectroscopy (FDS) and a discussion about the potential value of the data collected in depolarization mode, which are unique to TDS. Possibilities for improving the interpretive value of diagnostics using dielectric loss measurements will then be discussed based on the cumulated results of more than 14 years’ experience of testing in the lab and in the field.

      Until recently the underground electrical industry had to rely on a conventional cementitious thermal grout to dissipate heat from high voltage cables.  Cementitious grout naturally sets up and hardens over a relatively short period of time, thereby permanently locking the conduit and/or cable in place.  Furthermore, due to the short setup time for the cement-based grout, the only viable method of installation was by way of tremie lines pulled in at the same time as the cable.    This standard methodology required multiple expensive spacers to keep the cable conduits in fixed positions with respect to each other and away from the casing wall while the grout was pumped under high pressure through multiple tremie lines from the surface.  Electrical engineers regularly questioned the degree of “fill” using tremie injection and the corresponding potential development of “hot spots”. A solution to these problems is to first fill the casing with a thixotropic (non-cementitious) thermal grout and then pull the conduits into the grout, allowing the “open ended” conduits to simultaneously fill with grout to produce near neutral buoyancy.  Success has been recently achieved on parallel 7000’ HDD crossings in Florida.  R&D is continuing.

        1:35 – 2:05 – Is this the end of the line?  How to determine End of Life.  (Extruded cables.) – Nigel Hampton – NEETRAC
        It is intended that this talk will touch on the following topics:
        1. How do we define End of Life? There are many perfectly valid lives (maximum / typical, cable vs system, at installation vs after some period of operation). The key is to frame the questions and answers in terms of “Life Statements”, which consider conditions, rate (survival or degradation) & time; rather than the simple assertion of X years.
        2. Where we stand when asking about End of Life matters! Just like human mortality when you ask the life expectancy matters, the life expectancies at birth, age 21 and age 65 are different. The same is true in the utility world the life expectancy that is used at the genesis of a project to determine rate of return or to compare economics of differing solutions is not the same as that for a system at age 30 contemplation “run to failure” or activities that might “extend life”. Furthermore unlike humans (generally), in the utility world it is important to be clear whether we consider “repairable” (cable systems with replaceable accessories or cable segments) or “unrepairable” (cable only or joint only) cases.
        3. Can / should we estimate a life at all? If we can, what would these life statements look like? It might seem that the whole concept / activity of estimating a life expectancy is too difficult to tackle; however, this is incorrect as a properly constructed life statement can have a profound influence on purchasing / remediation / retirement strategies. When proceeding though, the most important feature to recognize and overcome is that the very human tendency to believe that there is a single simple answer (this is the Anchoring Bias). The construction of a life statement requires time and effort. Additionally the robust approaches recognize that the outcomes in terms of life will be determined by many factors such as:
        a. the physics of the device ageing,
        b. the demographics of the device population,
        c. the environments (physical and operational (i.e. maintenance is perhaps a chronic environment)) in which the devices operate
        d. the experiences (typically acute issues like failures / repairs / overloads etc.) that they encountered.
        The approach that will be discussed in this presentation recognizes the different factors and that there are two different, but complimentary approaches to life estimation. These are:
        – Estimates based on what we can test
        – Estimates based on what we can garner from surviving records of historical performance
        Traditionally these are treated separately, however if we embrace the diversity of approaches and inputs we can draw on the actuarial methods and develop distributions meaningful life estimates. In this presentation we will discuss examples for both cable and wood pole assets.

      • 3:55 – 4:25 – Medium voltage cable testing assessment  program based on analytical methodology to determine health of cable system of aging underground infrastructure.– Frank Dempsey – PP&L
        Data utilized to efficiently address assets in need of remediation or replacement and to eliminate the unnecessary replacement of cable systems that have not reached the end of their useful life. Methodology based on offline diagnostic testing system utilizing Time Domain Reflectometry and  VLF Technology. TDR is used for fault location in cables and evaluation of neutral integrity.  VLF technology utilizes three methods of testing: go/no-go withstand test to expose defects that the cable cannot hold the test voltage, Non-destructive testing, including tan delta test which provides the condition of the cable from end to end, and partial discharge testing which locates defects and their severity along the cable path. Test results are used to evaluate the health of the cable systems and prioritize corrective action. Understanding and performing appropriate testing and maintenance of high voltage cable systems helps ensure Transmission, Substation, and Distribution System asset’s remain a reliable part of utilities infrastructure.
