Subcommittee A – Cable Construction and Design
- 2:00 – 2:20 PM Subcommittee A Business, Yingli Wen, Chair and Brent Richardson, Vice Chair
- 2:20 – 3:00 PM Economical Service Option for Medium Size Industrial Customers, by Steve Daniel, Alabama Power
Abstract: Industrial customers with loads in the 1.5-5 MW range located in rural areas provide challenges for local utilities providing reliable and economical electrical service. Standard medium voltage circuits are not always readily available in the area. A unique and economical approach utilized at Alabama Power involves connecting to the 46kV transmission system to provide standard industrial 3 phase 480-volt electrical service. The industrial customers in many cases are providing automotive parts for manufacturers located in Alabama such as Honda, Mercedes, Hyundai and Toyota. Industrial loads ranging from 1.5 MVA to 5MVA are commonly served via 46kV to 480/277V pad-mounted transformers. The pad-mounted transformers are served by 46KV underground cable that is sourced from a nearby overhead 46kV transmission circuit. These installations although at 46KV are not substation class equipment but the cable risers, underground conduit and transformer pads are similar to medium voltage distribution installations. The installations have proven to be both economical and offer a standardized method of service for industrial customers. - 3:00 – 3:30 PM Break
- 3:30 – 4:10 PM Extending the Life of Secondary Service Cables with Silicone-Gel Injection, by James Steele, Dave Busby, Rodrigue Tonfack, and Nathan Laurie, Novinium
Abstract: Secondary service cables interconnect the distribution transformer to the end user’s service meter and form the last link in the power grid. For many utilities with buried secondary service cables failures are on the rise and can account for over half of their underground cable-failures. Utilities would typically be faced with the decision to create a replacement program or continue to make ad-hoc repairs. This presentation introduces silicone-gel injection as a new option for utilities to consider. Silicone-gel injection purges water from the conductor and forms a physical barrier against water intrusion that protects the conductor from corrosion. The service is non-invasive and causes minimal disruption to neighborhood homes and businesses. Compared to the choices of repair and replacement, silicone-gel injection is cost effective solution that can easily be integrated into reliability programs as a capitalized expense. The technology, application of service and field results will be discussed. - 4:10 – 4:50 PM, Achieving Long Cable Life Series (Part 5), By Michael Joseph and Ben Lanz, IMCORP
Abstract: A study spanning 10 years, including tens of thousands of commissioning tests and over 100 defect dissections in several internationally recognized laboratories, concludes the frequency of substandard partial discharge producing manufacturing issues have doubled in the last decade. While the number of defects is still relatively low, one can argue that any preventable, systemic issue should be addressed. One challenge to the quality control process manufactures have consistently pointed to is insufficient degassing temporarily hiding defects from factory partial discharge quality control (QC) testing. This presentation will cover likely causes of the QC failure, including a reaction between uncured conductor shield and strand-fill material, ways to improve factory QC processes, and potential solutions to address the problems. - 4:50 PM – 5:30 PM – Open

Design philosophy of the transition joint will be presented, together with EPR cable used in the project and required activities in preparation for the project – design considerations and training of the jointers. - 10:00 AM – 10:15 AM – Break
- 10:15 AM – 11:00 AM – “Cable Accessories as an Enabler to Recovering Railed Cable Systems”, Ruben Grund – Pfisterer
Supply of electric energy is crucial. Nonetheless failures may occur and need to be repaired as quick as possible. If a High voltage cable line fails, repair might require replacement of a cable section. Ideally the laying scheme may include additional length, or a spare cable is available. In many cases this is not given and an already available cable needs to be used. This presentation discusses possibilities of integrating a cable into an existing cable system that might not fit at first sight.

- 8:30AM – 9:10AM: “Overview and Illustration of Technical Factors Influencing Medium Voltage Cable PD Assessment Outcomes- Part 1″ , Sarajit Banerjee, Kinectrics, Jean-Francois Drapeau, IREQ (Hydro-Quebec Research Institute)
Abstract
With the development of technology over the last decades in terms of both voltage supplies and PD system characteristics, a growing variety of system options have been proposed to users in order to perform diagnostic PD assessment of medium voltage (MV) cables. This increased offering has raised a number of concerns as to whether the use of one system versus another could lead to different PD assessment outcomes. One of the most dominant factors in such concerns has been the physical effect of the characteristics (frequency and shape) of the voltage supply on PD behavior, which has been discussed frequently over the last 5-10 years in scientific forums.To compare results across different PD system options objectively, accurately and consistently, it is necessary to consider the complete set of parameters which play a role in field MV cable PD assessment outcomes, which include but extend beyond voltage supply characteristics alone. Such factors may be summarized as follows:
• Test source / type of applied stress
• PD measurement system characteristics including sensor strategy (hardware oriented)
• PD pulse discrimination and analysis strategies (software-oriented)
• PD localization strategies
• PD test methodology (protocol oriented)
Kinectrics and IREQ are undertaking a joint, independent experimental study to systematically demonstrate the effect of varying the parameters noted above in a controlled manner, to investigate their potential influence on MV cable PD assessment outcomes. This presentation will introduce and present preliminary results from this joint study, and discuss the different PD testing contexts in which considering such influences is crucial to the selection of a PD system or measurement set-up. Such contexts include the purpose of testing (e.g. commissioning [acceptance] vs condition assessment for maintenance), criticality of the test sample and test circuit characteristics (e.g. length, insulation type, accessibility).

This will be presented by Sarajit Banerjee - 10:45AM-11:20AM : “Alternating-Voltage HiPot Testing of Long Installed HV and EHV Extruded Cables”, Andrew Barclay, Kinectrics
This presentation will cover ac hi voltage testing of long-length HV and EHV cable systems and discuss some of the systems as well challenges - 11:20AM-11:55AM: “Lightweight Automated Diagnostic Device for On-Line Detection and Location of Partial Discharges on Non-shielded Accessories of a Medium Voltage Distribution Network” Lionel REYNAUD, Daniel PINEAU, Martin CHARETTE , IREQ (Canada)Abstract: PD Alarm is a device that offers a quick and safe method of detecting and locating partial discharges (PDs). The PD Alarm device (Fig. 1) includes two antennas that pick up the signals, an acquisition module, a processor, and a module to produce an alarm after detecting a partial discharge. The method includes the detection of two magnetic fields with the two sensors, the digitization of the two received signals, the processing of the two signals and the generation of a signal resulting from the processing. The processor is configured to issue alarm instructions if the resulting signal has a property representative of a partial discharge and remain in a standby state otherwise (ready for signal detection).
PD Alarm is able to detect the inversion of polarity of a PD produced between the two antennas at a range of operation below 30 MHz and centered around 18 MHz [1]. This low band frequency allows a much more standard and cheaper electronics for all necessary treatments than at higher frequencies. The development of antennas is also one of the keys to success. - 12:00 Noon – Wrap – up and adjournment

Subcommitee G – Transnational Luncheon (Registration Required) – Tuesday, October 22, 2019, 12:15 – 2:00 PM
- 400kV XLPE Underground Power Cable Projects in Qatar & Bahrain, Kazuhiro Yoneya, Furukawa Electric;
400kV XLPE power cable projects for Middle East countries completed in the past few years will be introduced. The projects feature challenges in civil work, monitoring system and conductor design. - Calculation of short circuit currents in cables with more then one metallic layer outside the insulation, European thoughts, George Anders, Anders Consulting;
The IEC 60949 standard for the calculation of the allowable short circuit parameters (either the current or the duration) is limited to a single-component screen. But most modern cables have two or more metallic components, one of them to guarantee that the screen will withstand the stated default current during the given time (typically copper wires or lead tube), and the other as radial moisture barrier (for example an aluminum foil). In these cases, both components can be connected in parallel, so they will work together in the case of a system fault. A new IEC standard is proposed include both metallic components in short circuit current calculations. This presentation will outline the proposal and will show the effect of the new calculation procedure on a short circuit capability of a typical cable with two metallic components outside the insulation. - PQ test on 500 kV test loop which is undergoing in Wuhan, China, Ivan Jovanovic, Grand Wu – G&W Electric Company;
500 kV underground cables have increasingly high stresses and design margins of the accessories are revisited in order for terminations and joints to be smaller, easier for installation and ultimately more competitive without jeopardizing reliability. This presentation provides one design approach that is meant to meet this goal by using dry type interfaces in 500 kV terminations and joints that are currently under PQ test. - Online Partial Discharge (PD) Survey 154kV Teias substation, Turkey, Landry Molimbi, Prysmian Electronics;
A portable for spot measurements continuous monitoring allows for PD testing to be performed online without any need for galvanic connection to the assets being tested, which also means greater safety for electrical parameters. This solution was deployed in Turkey to carry an investigation on HV underground transmission circuits with suspected PD activity. This presentation will demonstrate the diagnosis and localization of the source of PD away from / outside of the HV source of concern. We will describe the steps taken to find and to determine the “real” source of PD activity, hundreds of feet away from the original PD measurement point. - PD Testing of MV Power Cables on a Solar Power Plant in Jordan, Rene Hummel, EMEA;

Networking Luncheon (Registration Required) – Monday, October 21, 2019, 12:30 – 2:00 PM
- Welded sheath cable Designs – a utility’s concern, strategies adopted, and the final decision, Sudhakar Cherukupalli, BC Hydro
- Application of Temporary Site Cables for Substation Upgrades in Indiana, Mark Stemmle, Nexans USA
Temporary site cable solutions are self-contained connection systems for electrical substations. They are based on specially designed insulated high voltage cables with factory installed flexible terminations packaged on a single reel for ease of transport and deployment. These systems give a high degree of flexibility to utilities when performing work in substations. They allow part of the substation to remain in operation and to minimize clearance and safety issues compared to shoefly solutions. A temporary site cable system can be quickly deployed and energized, thereby minimizing the required outage time. The required upgrades or maintenance can then be performed on the bypassed part of the substation and, at the end of the work, the temporary site cable system can be rewound on the reel, stored, and reused at a later time. - Can we use Reliability Indices to estimate the impact of Undergrounding?, Nigel Hampton, NEETRAC
People consume more electricity than ever before and expect to have access to it without interruptions whatever the ultimate source. Authorities are increasingly interested in how well this electricity is supplied. This puts pressure on electrical utilities to provide evidence of the reliability of electricity distribution, especially when requesting amendments to rates to support improvements. It is fairly common to see regulators and utilities alike measuring the length and number of interruptions. Indices (SAIDI and SAIFI) described in international standards (IEEE) are used to quantify the reliability. Taken together these indices serve as valuable tools for capturing performance reliability.
Undergrounding is often suggested as one of the ways to build a more resilient electrical infrastructure and thereby improve reliability. Undergrounding is not a new phenomenon and many utilities have various amounts of underground distribution. Combining, at the distribution level, the Reliability Index data with the amount of undergrounding provides a way to investigate the relationship between Reliability and Undergrounding. - Trends in cable manufacturing compliance, Paul Knapp, UL
- Standardized PD tests Performed to the Industry Standards Produce Consistent Results Worldwide, Rene Hummel, Imcorp
- After installation test on HV cables in extreme conditions, Aron Sexton, Kinetrics
Abstract: The test equipment is rated for certain ambient conditions which usually do not go below -5 C and above +40 C. When testing in winter in Canadian North, -5 C is Spring or Fall temperature rather than Winter. This and other cases will be presented along with the challenges and mitigating techniques to ensure the equipment is operated within the specification in cold, hot and high altitude.

- 1:00-1:05, Introduction
- 1:05-1:49, “Intelligent Undergrounding at San Diego Gas & Electric” by Jon Erickson – San Diego Gas & Electric. This presentation will discuss various aspects of the underground medium voltage electric distribution system at San Diego Gas & Electric (SDG&E). Included will be a discussion of the reasons for the expansion of the underground electric distribution system from the 1960’s until today with the result being that more than 60% of the electric distribution system is underground. There will be a discussion of the aging unjacketed cable system and how it is being addressed by proactive cable replacement. Water in underground structures has resulted in extended outage time due to the necessity of waiting for pumper trucks to remove water from the structure prior to fault locating. The development of a water filter sleeve to address this issue will be discussed. Infrared inspection of underground cable connectors is an important operating practice prior to entering manholes or other substructures. SDG&E’s operating practice will be discussed and infrared camera examples of elevated temperatures in 600 amp tee connections will be presented. SDG&E has greatly expanded the use of a Supervisory Control and Data Acquisition (SCADA) system in the last 30-35 years on the overhead and underground electric distribution system to remotely restore service much faster than in the past. The deployment of this SCADA system will be discussed. The conversion of overhead distribution lines to underground in high fire risk and high wind areas will be discussed.
Jon Erickson is a Principal Engineer at San Diego Gas & Electric where he has worked for 41 years. Jon has worked for the past 24 years in the Electric Distribution Engineering group. His job responsibilities include medium voltage and low voltage underground cable and connectors, and overhead wire and connectors. He is also responsible for the Electric Distribution Design Manual. Prior to working in Distribution Engineering Jon worked at one of SDG&E’s operating centers for 8 years, and in Electric Distribution Planning for 4 years. Jon received his Bachelor of Science Degree in Electrical Engineering from California State Polytechnic University, Pomona. He is a member of the Association of Edison Illuminating Companies (AEIC) Cable Engineering Committee. - 1:49-2:33, “The Wisconsin Public Service Company System Modernization and Reliability Project” by Mike Smalley – WEC Energy. The Wisconsin Public Service (WPS) company System Modernization and Reliability Project (SMRP) was established to improve the reliability of approximately 2000 miles of electrical power lines (mostly overhead) that have the lowest system reliability. These lines are primarily located in heavily forested, rural areas of northern Wisconsin. These areas were targeted because the customers in these locations are repeatedly faced with the loss of power due to storms (sometimes for several days). This presentation will provide an overview of the project that includes discussion of the materials used and impacts on common system reliability indices.
Michael J. Smalley received a B.S. degree in Electrical Engineering Technology from the Milwaukee School of Engineering in 1991 and a M.S. degree in Engineering (Electrical) from the University of Wisconsin-Milwaukee in 2000.

He has responsibility for low and medium voltage underground cable and accessories. He is a Senior Member of the IEEE Insulated Conductors Committee and is a registered Professional Engineer in the state of Wisconsin. He also is a member and past Chair of the AEIC Cable Engineering Committee. - 2:33-3:17, “Eversource’s Underground Cable Program” by Demetrios Sakellaris. With the mounting level of scrutiny regarding legacy high pressure fluid filled (HPFF) systems and more specifically how they are monitored, the use of more sophisticated analytics to asses and identify system anomalies is growing in user adoptability. Eversource has selected and completed such a review for a pilot loop on their HPFF system and will share the lessons learned. The need to consider alternative cable technologies, particularly at critical environmental locations, is also of growing concern. There is an ongoing project in downtown Boston where the DOT is replacing an existing bridge that currently has two HPFF circuits that run along it. Eversource is currently in the design phase of converting this section of the circuits to XLPE with the use of transition joints.
Demetrios A. Sakellaris was born and raised in the greater Boston area as a first generation Greek – American, Demetrios earned his undergraduate degree in electrical engineering at Northeastern University. Upon graduating in 2010 and starting his full time position in the Transmission Engineering group at legacy NSTAR Electric (now Eversource), he made a decision to continue his higher education. In 2014 Demetrios completed his master’s degree in Power Systems Engineering and a second degree in Business Administration. He continues to play a critical role in the transmission organization at Eversource, most recently assisting in the company’s successful winning competitive bid for what is referred to as the “Greater Boston Suite” of projects. His experience includes all types of transmission line design (overhead and underground across various cable technologies), substation design, strategic planning and system hardening to developing multi-year capital budget programs. In 2016 he successfully obtained his Professional Engineering (P.E.) license in the Commonwealth of Massachusetts. - 3:17-3:32, Break

Training Session – Tuesday, October 22, 7-8 AM – Engineering Ethics
- Topic: Engineering ethics presentations typically involve a recital of the regulations and laws pertaining to the engineering profession (usually read directly from an overcrowded screen full of text). Not only do these lectures bore me, but it may actually be unethical for me to claim (PDH or CEU) credit for attending these mind-numbing presentations. As a registered professional engineer, I am already required to have a “working knowledge” of the applicable rules and laws. In 2018, I began researching engineering rule violations and ethics infractions to present to engineering colleagues around the world. These case studies offer constructive insights to guide engineers toward the ethical high ground. And – you will not need coffee to stay awake.
