    • 8:10-8:50 AM “Electrical Treeing in XLPE at High Altitude” by Mohamad Baferani, Kerry Davis-Amendola, Tohid Shahsavarian, Chuanyang Li, Wesley Zhong, JoAnne Ronzello, Roger Walker, Yang Cao, UL Solutions and the University of Connecticut
      • Aircraft electrification poses new challenges to the safe design of the insulation system under harsh operating conditions. This study focuses on the investigation of electrical treeing, a precursor to electrical breakdown in the bulk of electric wires and cables, under emulated low pressure and high temperature for high density electrification at high altitude. It was found in a model insulation of cross-linked polyethylene (XLPE) that low pressure and high temperature significantly decreased the treeing initiation voltage and increased tree growth propagation rate. Moreover, the presence and size of artificial air gaps affected tree morphology, growth rate, and fractal dimension in a way that decreases insulation durability.
      • This work could be used as a baseline for studying electrical treeing phenomenon at high altitudes with coupled high temperature-low pressure, to pave the way for the reliable design of insulation systems on the path towards high altitude electrification.
    • 8:50-9:20 AM “State-of-art in Semiconducting Compounds Manufacturing and QA, Designed for Cable Processing” by LeeAnn Chen and Suren Shah, Orbia Polymer Solutions

We have taken a more expansive approach in our design of the manufacturing process and the quality assurance parameters. We have defined the important parameters to include raw materials, in-process, and final semiconducting products. We will highlight the design of the manufacturing system and how we control the quality parameters within tight control limits. These ensure trouble-free and fast processing for the cable manufacturers.

    • 10:00-10:15 AM BREAK
    • 10:15-11:00 AM “Covered Conductor Flammability Research – Part 2” by JC Hernandez-Mejia, Ray Hill, and Bryan Davant, NEETRAC
      • Covered conductor also known as tree wire has been used for several decades in the United States for overhead distribution system hardening. As a consequence, almost all utilities in the country use covered conductor to some degree in their overhead distribution systems.
      • Covered conductor is a critical component of power distribution systems in California. The conductors are designed to protect electrical distribution lines from the harsh weather conditions prevalent in the state, such as high winds, and storms.
      • Most recently, utilities in California are contemplating a considerable increase in usage of covered conductor due to their inherent capability to limit the contact current when an external agent such as a tree branch contacts the line. The limitation of the contact current by the covered conductor greatly reduces the risk of a wildfire ignition from the overhead primary distribution system.
      • However, once the covered conductor has been deployed, there are questions that remain unanswered. They are specifically related to the flammability of covered conductor in two potential scenarios that may manifest in the field. These scenarios include understanding the flammability of the covered conductors when they are subjected to a fire/heat wave and an electric arc.
      • The presentation will show results from a research program that led to a repeatable testing protocol which approximates actual field conditions to determine the flammability and sensitivity of covered conductors under a fire heat wave.
      • This is a follow-up presentation for the work that was presented in Spring 2024.
    • 11:00-11:40 AM “Ongoing research into failure rates and demographics of cables in North America” by N. Hampton, D. Lewis, J. Perkel, J. Potvin, EPRI
      • Industry surveys regularly indicate that there is significant concern with the performance of ageing assets on the distribution grid coupled with the need to increase the reliability. Undergrounding is seen as an effective way to address failures and improve reliability: reducing indices correlate with increased undergrounding. One of the significant challenges to managing the underground assets is the range of different cable technologies and their diverse ages. Establishing the appropriate remediation approaches depends upon a good understanding of the failure rates and demographics. Unfortunately, this knowledge is not straight forward to develop. Where it exists the information usually resides as “Institutional Knowledge” within long tenure employees. Yet increasingly the asset management decisions are being made by staff with less experience and without context for the “Institutional Knowledge”.
      • This presentation shares some of the methods and outcomes of ongoing research work designed to
        • Estimate the magnitude of underground failure rates of the distribution system being operated today
        • Understand the ranges and uncertainties associated with these estimates
        • Establish the demographics (ages, lengths) of the current components

      • The Union Station Enhancement Project (USEP) is a key component of the GO Expansion program, which aims to revolutionize the transportation network in the Greater Toronto and Hamilton Area over the next decade. This project plans to expand the corridor by installing additional rail tracks to the east between Union Station and Wilson Yard near the Don River. Consequently, it requires the removal and relocation of Hydro One’s (HONI) existing double circuit overhead transmission lines H9E and H10E, as well as the 115 kV underground high-pressure oil-filled pipe-type cable circuit H2JK. The project involves decommissioning the existing three HVAC circuits and replacing them with three 115 kV XLPE underground circuits.
      • This presentation will review the 115 kV XLPE underground cable system. The cable route design considers the impacts of other construction activities, such as the rail corridor expansion, and the constraints of the right-of-way (ROW). The construction sequences for site grading, decommissioning existing circuits, and installing new underground circuits are analyzed to understand potential risks related to ampacity and duct bank design. Additional challenges include navigating the crossing of various existing underground utilities and ensuring all key stakeholders remain engaged in the cable bridge design process.

    • 3:30 – 4:15  – “AMS Topical Report on Condition Based Qualification, Condition Monitoring and Life Extension” – Trevor Toll, Casey Sexton, Adam Deatherage, Dr. H.M. Hashemian – AMS Corp., Knoxville, TN
      • Abstract – In August 2024, AMS submitted a topical report to the NRC that describes a cable condition monitoring methodology that has been developed through a number of research and development projects involving hands-on laboratory measurements and material analysis. The primary objective of the methodology is to extend the service life of electrical cables as installed in nuclear facilities. In addition, it can help quantify the aged condition of cables, make objective decisions about cable repair and replacement schedules, satisfy plant life extension requirements, meet the cable aging management objectives of the nuclear industry, and supplement the time-based approaches currently used to determine cable lifetime. The development of the methodology was stimulated by license renewals of nuclear power plants to operate 60, 80, or more years. The methodology is applicable to safety and non-safety related electrical cables governed by 10 CFR 50.49 (Environmental Qualification), 10 CFR 50.65 (Maintenance Rule), and 10 CFR Part 54 (License Renewal). It provides a conservative approach with adequate margin for assessing the aged condition of cables against objective acceptance criteria. Therefore, it can be used in lieu of or in addition to the current nuclear industry practice for cable life extension and aging management.
      • The methodology involves four elements as follows.
        • Select cables as installed in the plant to be included in the condition monitoring program.
        • Identify condition monitoring measurements that trend with the age of selected cables.
        • Establish acceptance criteria for results of condition monitoring measurements.
        • Apply the measurements and acceptance criteria identified above to evaluate the current condition of selected cables and use the results to determine how often the cables must be tested as the plant continues to operate.
      • This process applies to all electrical cables that have polymeric insulation and/or jacket materials regardless of how long they have been in service, their service environment, or their significance to plant operation and safety.

Toll is the Lead Engineer for the Materials Testing Laboratory at Analysis and Measurement Services Corporation (AMS) and specializes in testing of industrial materials and components including cable insulation. Since joining the company in 2014, he has supported a number of commercial and research and development (R&D) projects through laboratory testing and analysis of materials. Over the last decade, Mr. Toll has been responsible for developing AMS’s laboratory materials testing capabilities. These technologies provide a comprehensive suite of analysis tools that are utilized to conduct condition assessments of materials and components used in systems across various industries and facilities, including nuclear plants, the transportation sector, and data centers. Mr. Toll is one of the authors of the AMS topical report entitled, “Condition Monitoring Methodology for Life Extension and Aging Management of Electrical Cables.” This topical report describes a cable condition monitoring methodology that has been developed through a number of research and development projects involving hands-on laboratory measurements and material analysis. The primary objective of the methodology is to extend the service life of electrical cables as installed in nuclear facilities. Prior to the topical report, Mr. Toll served as a project manager for the R&D project that lead to the development of the AMS cable condition monitoring methodology. This R&D effort was funded by the U.S. Department of Energy’s (DOE’s) Office of Nuclear Energy and titled, “Development of Cable Aging Acceptance Criteria for Nuclear Facilities.” Under this project, AMS collaborated with researchers at Oak Ridge National Laboratory (ORNL) and Pacific Northwest National Laboratory (PNNL) to develop aging acceptance criteria for condition monitoring (CM) tests that have shown to trend with age-related degradation of cable insulation polymers. These criteria can be used to provide a quantitative assessment of the aged condition of cables installed in nuclear power plants as well as other industrial applications.

    • 2:10 PM – 2:45 PM “Methods and Experience of Diagnostic Testing to Support Asset Management of MV Cable Systems using Off-line 60 Hz Partial Discharge Measurement Techniques”, Geon Seok Lee, Qasim Khan, and Jean Carlos (JC) Hernandez-Mejia, Georgia Tech NEETRAC. Medium voltage (MV) power cable systems are critical components of power distribution networks, and their failure can lead to costly outages, safety hazards, and operational disruptions. Diagnostic testing, such as partial discharge (PD) measurements, time domain reflectometry (TDR), dissipation factor (Tan δ), and others, play an important role in identifying systems before catastrophic failures occur. By proactively assessing cable system condition, utilities and industrial operators can prioritize maintenance, extend asset lifespan, and optimize replacement strategies and budgets. Effective diagnostics reduce unplanned outage time, improve system reliability, and support data-driven asset management decisions. While diagnostic tools provide valuable insights into cable condition, their field application presents challenges not encountered in controlled laboratory environments. Factors found in field applications can influence measurements, making results harder to interpret. This gap between theory and real-world performance underscores the importance of continuous learning from field experience. By systematically analyzing new diagnostic data and correlating findings with actual failures, it is possible to refine test methodologies, improve diagnostic accuracy, and enhance predictive maintenance strategies. Each new dataset contributes to a deeper understanding of how these tools perform in practice, ultimately leading to more reliable asset management decisions. Therefore, this presentation explores the application of off-line 60 Hz PD diagnostic testing as an important tool for asset management of MV cable systems. Based on a proactive testing and replacement program, a comprehensive dataset was collected through extensive field measurements. Significant effort was dedicated to data gathering, validation, and cleaning to ensure a meaningful analysis. The results are investigated by PD location (i.e. cable, splices, and terminations) providing insights into failure mechanisms and defect location distributions. PD measurements diagnostic indicators have been correlated with location and condition assessment outcomes. These findings serve as a benchmark for expected PD behavior in MV cable systems, supporting the development of future proactive maintenance strategies. The discussion highlights practical challenges, diagnostic interpretation, and the value of PD testing as a tool for MV power cable system condition assessment.
    • 2:45 PM – 3:20 PM “PD study on DAC vs. 50/60 Hz”, Rene Hummel, Kinectrics. A direct comparison of PD behaviour and PD assessment outcomes between Damped AC (DAC) and 60 Hz test voltage is conducted on a variety of MV cable defect types. Key parameters compared across the two test source types include PDIV, PDEV, discharge magnitude (pC), PRPDs and PD event counts / repetition rates. The paper aims to provide end-users with an independent understanding of what impact (if any) may occur on the same type of defect when utilizing a DAC based versus 50/60 Hz based PD measurement system. The study clearly illustrates the defect specificity / dependency of results obtained, which contrasts with other studies which have often drawn broad conclusions regarding source effects from a relatively small range of defect types. The implications of the work extend directly to PD testing of MV cables in commissioning contexts. However, indirectly, the results are likely applicable to higher voltage class cables as key behavioural dependencies observed are expected to be present at higher voltage stresses relative to those considered in this study. The study also provides an OEM independent, broad range of results which can support discussions within ongoing standards development efforts, and hopefully translates into end-user guidance to increase the accuracy and repeatability of field PD measurements, particularly when executed with DAC sources.

    • 3:50 PM – 4:25 PM “A retrospective analysis of XLPE Cables tested in the Field”, Nigel Hampton and Joshua Perkel, EPRI. Late in the last century, EPRI undertook a major study (Rpt: 1001892) of Health Assessment approaches. As part of the work measurements of XLPE cables at ten different utilities, these cables were then extracted and characterized by laboratory testing. It was recognized that this work represented a considerable resource. Thus, it was decided that it would be valuable to reexamine these data to avail ourselves of new methods, perspectives, or objectives that were not considered during the original reporting. This presentation looks at the insights that the breakdown strength and water tree analyses bring for dielectric loss evaluations in the field.
    • 4:25 PM – 5:00 PM “On-Site test voltages in the field – comparative measurements on real PD failures in MV and HV cable networks”, Daniel Müller-Bode, Daniel Götz, Megger. Partial Discharge (PD) diagnostics are essential for evaluating the condition of power cable insulation in medium- and high-voltage cable networks. As traditional withstand testing only reveals critical insulation issues that lead to a fast breakdown, other insulation defects related to PD activity and long-term breakdown will not be discovered during these tests. Here, the PD measurement technique is the technology of choice to secure proper workmanship of cable laying and jointing. This presentation provides a comparative analysis of On-Site PD measurements conducted under various commercially available test voltages. Measurements were carried out on real cable systems to evaluate the performance and diagnostic capabilities of each method. In the first part of the presentation, PD testing on MV-cables is presented using VLF-Sine, VLF-CR and Damped AC voltages. Key PD parameters – including PD inception voltage (PDIV), pulse amplitude, phase resolved patterns, and time-domain reflectometry – are compared across techniques. In the second part, an HV cable system was tested using both conventional AC resonance with HFCT-based PD detection and a DAC approach with TDR-analysis. This comparison highlights differences in sensitivity, localization accuracy, filter methods, sampling rates and bandwidth resulting in possible differences in diagnostic effectiveness. To finalize the comparison, a PD active joint was cut out and investigated after the tests to find the root cause of the PDs.

    • 1. Challenges in substations – Thermal calculations and safe works under induced voltages in Greece, by Polyxeni Karavida, Hellenic Cables, Greece
      • Abstract: Substations with complex configurations present significant challenges in thermal calculations and safe works under induced voltages. This study focuses on a Greek high-voltage (HV) substation with a particularly intricate layout, featuring nine 150 kV overhead lines transitioning into underground cables that traverse the substation and intersect with two 400 kV cable circuits under installation. The underground cable network within the substation comprises over 20 crossings at various voltage levels, from Low Voltage (LV) to Extra High Voltage (EHV), installed at different depths and angles. These crossings can create thermal hotspots, potentially impacting cable performance and ratings. To ensure the proper sizing of the cables, a detailed thermal analysis is required, with a 3D finite element thermal model being essential for accurately assessing such a complex installation. Additionally, the works of terminating the two 400 kV cable circuits under installation necessitate an evaluation of induced currents and voltages to ensure the safety of personnel. By employing electromagnetic transient analysis for both normal operating conditions and short-circuit scenarios, this study identifies the maximum induced voltages and currents, highlighting the worst-case scenario—a fault between an overhead line conductor and the substation’s local earth. Based on these findings, appropriate Personal Protective Equipment (PPE) can be identified by the installer/contractor to safeguard workers during installation.

    • 3. Submarine Cable Development Project in Japan Towards Carbon Neutral 2050 by Tomohiro Ishikawa, Furukawa Electric, Japan
      • Abstract: Japan is planning to introduce a huge amount of renewable energy, ranging from 30 to 45 GW, to achieve Carbon Neutral 2050. many national development projects related to renewable energy and transmission technologies are being promoted under government leadership. Furukawa Electric is involved in several of these development projects. The introduction of offshore wind power is planned as a key source of huge amount of renewable energy. In addition to the bottom-fixed offshore wind along the coast, the introduction of the floating offshore wind power in offshore areas is being considered. Regions with high potential for offshore wind power are located far from major power demand areas such as Tokyo metropolitan area. Therefore, the construction of a direct current submarine transmission network of several hundred kilometres to connect the power generation areas and demand areas is being considered. When advancing such cable projects, Japan’s coastal seabed topography includes many deep areas. Avoiding deep-sea areas by routing cables along shallow coastal areas can lengthen the cable route, leading to disadvantages in terms of installation time and project costs. Cables that can be laid in deep sea are important because shortening the cable route by taking shortcuts through deep sea areas is desirable for reducing transmission losses and costs (e.g., shorter installation times). Furukawa Electric has developed HVDC submarine cables using XLPE insulation materials that can be installed in deep sea (1000m to 1500m) and has evaluated their mechanical and electrical properties. This presentation introduces the results of these developments.

      • Abstract: In Japan, the ageing of transmission cables has become more significant than in the last decade. Gas analysis on cable joints and XLPE cable terminations indicate a growing sign of deterioration. However, due to the decrease in maintenance personnel, Condition-Based Maintenance (CBM) is preferable. We attempted to install on-line PD monitoring system and to analyse deteriorated 66kV XLPE cable feeder and 275kV SCOF cable feeder in Tokyo.

    • 7. Field HVDC Testing Experience in Europ by Raed Ayoob, Kinectrics, UK
      • Abstract: Transmission power networks across the world are experiencing a significant transformation in terms of expansions and upgrades due to increased transmission power demands. This is largely a result of the rapidly increasing number of interconnectors and offshore wind farms being integrated in power transmission networks, more prominently in Europe currently. High Voltage Direct Current (HVDC) systems offer an energy efficient method of transmitting large amounts of power over long distances, making it an ideal system to be employed in critical systems such as interconnectors and export cables in offshore wind farms. As with any newly installed cable system, there is a possibility that the cable system experiences installation damage originating from transportation, installation, or workmanship issues that would limit the life of the cable system. Therefore, commissioning testing is a critical step in the lifecycle of the cable system as it provides the asset owner with assurance and confidence that the cable system will operate reliably when put into service.  This presentation sets out to describe the features and capabilities of a modern test set designed for testing very long HVDC cable systems, along with practical experiences of European field tests carried out on HVDC cable systems and HVDC gas-insulated switchgear (GIS) systems.
