- Subcommittee A – Cable Construction and Design
- 8:00-8:30 PM Chairman’s Opening Remarks and Announcements
- 8:30-9:00 AM “Influence of the insulation screen and strip force on the wet ageing results of cables” by Detlef Wald, Eifelkabel. The presentation will deal with the influence of different strip forces on thermoplastic cables on the wet ageing results of these cables. We will present different formulations and different processing and have evaluated and related this to the water treeing behavior of these cables. By modifying the insulation screen we adapted the adhesion of this screen to the insulation. We kept the formulation for the insulation and the conductor screen constant and also the polymers in the insulation screen where kept the same. The cables were produced under the same condition. The water tree behavior was testing according to Cenelec HD 605, 500 Hz on 11 kV cables.
- 9:10-9:40 AM “Routine Factory and Field QC Testing: Can We Do Better?” by Ben Lanz and Charles Shannon, IMCORP Edison Electric Institute (EEI) reports underground cable system performance is about nine times more reliable than overhead lines but from a life-cycle standpoint, even this failure rate is over ten times higher than necessary. North American utilities plan to significantly increase their underground investments to improve resiliency and some have expectations of 60 to 100-year life. These resiliency and longevity goals will not be achieved unless industry specification and standards improvements are made. Tens of thousands a miles of shielded power cable are routinely tested at factories each year in North America. Using a comparable technique over a quarter of a million cable systems have been tested in the field and tens of thousands of cable systems have been monitored and over 8,000 dissections performed over the last two decades resulting in the following conclusions: Nearly 40% of newly installed systems have at least one substandard component (defect); Over 90% of cable failures are associated with anomalies existing at the time of installation; Over 90% of newly installed defects will last years if not decades before failure; An aged cable is 6 times more likely to fail again after the first fault; Many installers do not have the skills to identify defects during installation. The authors welcome industry colleagues to attend this presentation to consider and critique data, rationale, and specific recommendations on how cable owners can achieve over ten times higher reliability and cable manufacturers can reduce unjustified warranty claims by 95% simply by harmonizing and tightening QC test specifications.
- 10:00 -10:15 AM BREAK
- 10:20-10:50 AM “Protecting Secondary-Service Cables from ac Driven Corrosion” by James Steele, Nathan Laurie and Wayne Chatterton, Novinium. The injection of silicone-gel purges water from the conductor and forms a physical barrier against water intrusion and limits corrosion. This presentation discloses results from laboratory-based studies performed which compare corrosion of standard 600V triplex cable with aluminum conductors and the same cable injected with a silicone-gel under extremely corrosive, field-like conditions. The laboratory environment involves alternating current between triplex conductors with jacket breaks which are immersed in saltwater. Measured by resistance, ampacity, and corrosion rate, the data reveal silicone-gel injection’s ability to restore and preserve the integrity of the triplex when applied in both reactive (jacket breaks exist prior to injection) and proactive (jacket breaks occur post injection) manners. Further, the observed impact of parameters such as cable construction unbalanced loading on corrosion rate and cable lifetime will be discussed.
- 11:00-11:30 AM “Time to failure testing of submarine cables in saltwater at high temperatures and electrical stress” by Sverre Hvidsten, SINTEF. Installation of high voltage (66 kV) rather than medium voltage (36 kV) inter-array cables for bottom-fixed and future floating wind farms reduces the number of cable strings resulting in a significant overall cost benefit. New cost-effective high voltage subsea cable designs include so-called wet designs allowing water molecules to enter the HV cable insulation system during service. Time to failure (TTF) testing can provide data to empirically model the service lifetime of the cables at a lower service stress. For high voltage cables, the needed electrical stress during TTF testing can be very high, and there are several challenges associated with testing. This includes premature breakdowns at the terminations, anomaly ageing at the water surface due to non-radial temperature and water diffusion gradients, and finally very high electrical stress in the insulation causing less relevant ageing. This presentation includes results from a TTF test set-up and test program to model HV cable cores soaked in salt water. A TTF test of model HV subsea cables using medium voltage XLPE cable cores was completed at a high stress of 30 kV/mm at the conductor screen and 70 °C in salt water”.

- Ampacity Considerations in Designing Long AC cable Lines with Reactive Compensation, by Dr. George J. Anders, aco Anders Consulting Ltd. and Mr. Remigiusz Joeck, PNE Group,
Recent push for the renewable electrical energy sources has resulted in a significant increase in the installation of the on- and offshore wind farms. These farms become much bigger that their earlier counterparts and the generated power is much larger. This puts additional performance requirements on the export cables. Long cables are not only subjected to changing laying conditions along the route, including depth and soil variations, but also the loading patterns vary significantly over time. Additionally, applied reactive power compensation measures and the time-dependent grid situation change the distribution of the current along the route. These unique features of long power cables necessitate new type of approach to their design and construction optimization. This presentation introduces a new approach for ampacity calculations of long AC power cables. The approach is based on the adaptation of the ATP-EMTP software. The approach permits, for the first time, taking into account all the important parameters of the analysis simultaneously. Several numerical examples illustrate an application of the proposed methodology.

- Cables for Class I, Division 1 and Zone 1 Hazardous (Classified) Locations – Past, Present & Future, by Phil Laudicina,
- Subcommittee F – Field Testing and Diagnostics
- 2:00 PM – 2:15 PM Chairman’s Opening Remarks and Announcements
- 2:15 PM – 2:45 PM “A Multi-tool Approach to MV / HV Cable Testing: The only way to determine the true condition of a cable system,” Craig Goodwin, HV Diagnostics, Inc. Not unlike the medical diagnosis of a human being, where there is no single medical diagnostic or treatment that can determine all possible ailments in a patient, cable systems are also made up of multiple “body parts”. They are comprised of not only the cable itself with its multiple layers, but a whole host of various cable accessories. While it would be great if only one diagnostic test could detect all ailments, the reality is, if the only tool you have in your toolbox is a Phillips head screwdriver, you better hope all screws you come against in the field are also Phillips style heads. Unfortunately, you are bound to come up against a variety of other commonly available screw heads, rendering your tool useless. The presentation provides a short background to commonly used test methods and presents examples to illustrate where one test effectively detects an issue in a cable circuit, while other techniques simply do not. That’s not to imply in any way that these other tools are bad or useless. You will still need the Phillips head screwdriver in your toolbox, but don’t simply rely on one diagnostic tool, with the unrealistic belief that it will find all your of cable’s ills.
- 2:45 PM – 3:15 PM “Time-Domain Reflectometry – Challenges and Solutions for Long Distance Cable Applications,” Daniel Götz, Megger. TDR is a well-known and widely successfully used method for various of applications. It is mainly used for simple determination of cable length and positioning of impedance changes. Recent trend towards to remote offshore power generation or even interconnection links between countries require TDR application in distances of hundreds of kilometer. Dedicated smart techniques for improving SNR (Signal-to-Noise Ratio) are needed to pass the challenges. The presentation will provide theoretical explanation and practical application examples.
- 3:15 PM – 3:45 PM Break
- 3:45 PM – 4:15 PM
- “From A to Z – Methods, Experiences, and Lessons Learnerd from the Installation of a Critical MV Power Cable System,” Jean Carlos Hernandez-Mejia, Georgia Tech NEETRAC, Joshua Perkel, EPRI, and Nigel Hampton, UL. This presentation will discuss methods and experiences with diagnostic testing and analyses to support the asset management of new critical MV power cable systems from the factory to commissioning. The definition of a critical MV power cable system will likely change from utility to utility; different specific cases may require unique parameters in order to define whether a power cable system is critical or not; however, there are common parameters that remain constant across utilities perspectives that will be discuss with the group. To complement the discussion, a case study will be presented to illustrate the application of the asset management strategies of new critical MV power cable systems. Specifically, the case study corresponds to a new power cable system that is considered de facto critical because it is a bay crossing in the USA with limited/restricted accessibility once it is put into service. Additionally, the cable system delivers electrical power to a high-profile tourist area with high impact on the local and State economy. The approaches that will be considered and discussed are: Cable system technology selection; Tests performed in the laboratory; Quality assurance tests; Tests performed in the factory; Verification of cable integrity after transportation; Commissioning; Future performance assessment; Important lessons learned from each of the items above will be presented to the group. The work that will be reported can be used as guidance by utility engineers to maintain reliable operation of their important new cable critical assets.
- 4:15 PM – 4:45 PM “MV Power Cable Condition Assessment Using Frequency Domain Spectroscopy,” by Ali Naderian, METSCO Energy. Frequency domain spectroscopy (FDS) is relatively new diagnostic technique to evaluate the insulation of an MV XLPE cable system. FDS is the measurement of the dissipation factor (or tan δ) of the cable insulation over different frequency ranges. In the case of MV XLPE cables, the typical frequency range utilized is 0.01 Hz to 10 Hz which can go up to 1000 Hz.
This presentation provides a summary of historical works and also proposes criteria for the condition assessment of MV XLPE cables using Frequency Domain Spectroscopy. A zone-based categorization of aging effects on MV XLPE cables has been developed over a wide frequency range. The results show that dielectric loss spectrum of an MV XLPE cable is affected by thermal aging, water treeing and the effect of joints.
The categorization of tan δ measurements into zones would allow for interpreting FDS test measurements more accurately and discerning which frequency ranges are useful in identifying certain aging effects on MV XLPE cables.
- 4:45 PM – 5:15 PM “PD Measurements in Hybrid Electrical Assets: Power Electronics and DC Supply,” Gian Carlo Montanari, CAPS-Florida State University. Non-sinusoidal voltages in electrical assets propose new challenges: materials, life models, design, diagnostics. Practical approaches providing electrical diagnostic quantities to evaluate aging condition and likelihood of premature failure are not easily available and require specifications and standards, plus expert education. PD measurements are always an issue, due to noise, lack of reference patterns and voltage (for DC), and tools for the identification of the type of source. What do we need to develop?: Techniques for separation of signals belonging to noise and different PD sources, recognition of PD and noise, Identification of PD typology (harmfulness): this must be developed for DC and AC, being the basis for any diagnostic inference (note that transient DC generated PD as in AC); Diagnostic property trending, automatic alerting, Dynamic Health Index, residual life; All these features should become automatic and unsupervised, in order that there is no need of experts for diagnostics (but experts are fundamental to devise/implement maintenance actions). This presentation deals with problems, solutions, tips and tricks for PD measurements in electrical assets supplied by hybrid sources, focusing on DC voltage. An automatic, unsupervised PD detection approach is introduced.

Abstract: The Dutch TSO Tennet has decided to replace the majority of their 150kV substations over the coming 10 years. To allow for an uninterrupted power supply, the function of the old substation needs to be taken over by a temporary, mobile substation while the replacement plan is executed. To make this plan possible, temporary cable connections are needed to connect the mobile substation with the existing network. These cable connections are pre-connectorized cables that can be plugged in and out of the GIS and outdoor terminations and are suitable for multiple use. The presentation will focus on the preparation and use prefabricated temporary cable connections.
- 154kV Retrofitting Project in S. Korea by Chun Won (C.W.) Lee, Taihan, USA. Abstract: This presentation introduces the 154kV retrofitting project, which was completed in S. Korea last July. The existing cable was an aging self-contained oil filled cable for more than 30years. We replaced this oil filled cable with a new XLPE cable system. To maximize cable ampacity, we designed a triplex cable. In case of Triplex cable, the reel size is very huge because it has to wrap 3 phases around one reel. However, the project site was a high-traffic area, so should block all traffic for the cable pulling. To solve this problem, we developed a new pulling machine and could implemented the cable pulling without blocking the traffic. In the presentation, we will provide more details of 154kV triplex cable design, new pulling machine, actual cable pulling processes with photos & drawings.
- Update on Technical Brochure, Installation of submarine power cables by Søren Krüger Olsen, Ørsted, Denmark. Abstract: An update of the contents and status of the CIGRE Technical Brochure (TB) will be provided. A CIGRE working group B1.65 has over the last 3 years written a guideline concerning installation of submarine cables. The guideline is intending to cover the entire life cycle of a submarine cable project – from project idea through consent and permitting aspects, engineering aspects, vessels/tool but also including aspect like operation and decommissioning. The focus of the work is the installation aspects themselves. The electrical and electrical requirements on cables are handled by other recommendations and standards. The TB has been accepted by CIGRE Study Committee B1. September 2022 the document is being considered by the overarching CIGRE organization for publishing later during 2022.
- Testing experiences of XLPE and external gas pressure HV cables in the Netherlands by Daniel Götz, Robert Probst, Megger, Germany. Abstract: This contribution shows practical case study of Dutch power companies Qirion and Alliander of after-laying testing and maintenance testing of HV power cables by applying PD monitored damped AC voltage testing. In particular this presentation shows that applying non-destructive after- laying testing the repair of the cable circuit without causing real damage to the weak point is possible.
- Long connection between Lima’s substations in urbanized area by Marcin Kocik, Przemysław Krawczykowski, Tele-Fonika Kable, Poland. Abstract: In 2019 Tele-Fonika Kable was invited to take a part in project owned by Luz Del Sur. The project concerned connection between two stations near Lima in Peru i.e. Manchay – Pachacútec. Cable length hovered around 110 km. It was assumed that 1600 mm2 Milliken copper conductor should be used. Also it’s metallic screen should possess the ability to withstand short-circuit current equal to 40 kA / 0,5 s. The most challenging was the fact that the route forced to consider various laying variations. To make things worse, majority of the path is localized in the urbanized area. Combining above together lead to many detailed calculations e.g. induced voltages, pulling forces, bending radius and also specific drums. On the other hand detailed project data, detailed calculations, strong and practiced team, many trainings, more rigorous tests, Peru and worldwide market experience allowed Tele-Fonika Kable to successfully finalize the project.
- Global Monitoring System (GMS) for Underground High-Voltage 380 kV Circuit in Europe by Julio Toko, LIOS/LUNA and Alfred Mendelsohn, Power Delivery Solutions/Doble, USA. Abstract: The presentation introduces and describes the implementation of a Global Monitoring System (GMS) for a utility in Europe. We define the Global Monitoring System (GMS) as a combination of multiple sensing systems in a single software platform. This project is one of a long series of the digitalization program of the utility’s grid. The project presented is a 6.6 Km (4.1 miles) underground single 380 kV circuit with 11 joints per phase (33 joints in total). For this project and circuit, the GMS was comprised of a fiber-optic Distributed Temperature Sensing (DTS) with RTTR and Distributed Acoustic Sensing (DAS) systems for the entire route of the circuit in combination with Permanent Partial Discharge Monitoring (PDM) and Screen Current Sensors (SCS) for each 33 joints. The successful project represents the future of underground HV cable monitoring.
- Partial Discharge (PD), temperature (DTS/RTTR) and acoustic (DAS) monitoring of Eleclink HVDC interconnector – anticipate failures to minimize service disruption and impact on train circulation. by Diego La Cascia, Giuseppe Fiscelli, Alessandro Pistonesi, Landry Molimbi, Prysmian Electronics, Italy. Abstract: In this contribution the features of an asset management monitoring system, fully conceived, designed, built and installed for the 54 km long Eleclink interconnector between Folkestone (UK) and Coquelles (FR) will be presented. The Eleclink is a unique interconnector, being the first in HVDC, laid in air in a railway tunnel and in close proximity to the running trains. The Partial Discharge (PD), Distributed Temperature Sensing (DTS), Real Time Thermal Rating (RTTR) and Distributed Acoustic Sensing (DAS) monitoring system have been mounted along the UK/FR HVDC link and along the 14 km long HVAC power system between Folkestone and Sellindge in UK. In this HVAC link, the asset monitoring system is able to control not only the above-mentioned parameters but also the status of the Sheath Voltage Limiter (SVL), the sheath currents and the earth currents along the circuit”.

- Educational Program – “Offshore Wind Application of Submarine Power Cable”- Wednesday 1:00 PM – 5:00 PM
- As of 2022, the Bureau of Ocean Energy Management within the US Department of the Interior has leased 27 commercial offshore wind farm areas along the eastern seaboard of the US, with additional sites planned. The goal is to supply 30 GW of offshore wind power to the mainland grid by 2030. The connections from turbines to grid will be using submarine cables.
- Offshore wind farms have been in service in Europe for over 30 years, but until now only 7 offshore wind turbines (0.042 GW) are in service within the US. This educational session will cover the basics of both AC and DC high voltage submarine cables that will be used to connect the wind farms to the mainland grid. Experienced panelists from manufacturing, installation, and wind farm developers will share their knowledge of submarine cable systems applicable to offshore wind farms. A Q&A session with our panelists will be included.
