- 10:05 – 10:20 AM — Break
- 10:20 – 11:35 AM – SubA Business and Awards Presentation, Yingli Wen and Brent Richardson
- 10:35 – 11:15 AM – Intelligent Undergrounding at San Diego Gas & Electric, Jon Erickson*, San Diego Gas & Electric
Abstract: 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 new 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 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.
- 11:15 – 11:55 AM – Crosslinked Polyethylene Material Technology with Reduced Volatile Byproducts, Yabin Sun and Paul Caronia*, Dow Chemical
Abstract: Crosslinking of polyethylene-based insulating materials provides a means to increase temperature ratings (ampacity) of the manufactured cable. For medium voltage distribution and higher voltage transmission applications polyethylene crosslinking with dialkyl peroxide initiators has become the dominant chemistry, and the use dicumyl peroxide provides reaction kinetics which are very well suited to the power cable manufacturing process. However, crosslinking with dicumyl peroxide yields undesirable byproducts, such that additional manufacturing processes and/or time are required for sufficient removal of these byproducts prior to completion and testing of the finished cable. New crosslinking chemistry has been developed which significantly reduces the amount of byproducts in a manufactured cable, and thereby reduces the required time for subsequent cable manufacturing processes.

- 9:55AM – 10:30AM – “Understanding Electrical Stress Plots: What They Show as Well as Their Limitations” By Glenn Luzzi, Richards Mfg.
Developing electrical stress profiles of medium and high voltage components is a tool widely used for many reasons including design and development of new component designs as well as for understanding product failure modes not readily understandable otherwise. However, many times such analysis is performed to justify or present a design without offering the necessary criteria which justify the values observed in the stress analysis. This presentation tries to show what information can be extracted from a stress plot as well as the limitations of such analysis.
Glenn Luzzi graduated from Stevens Institute of Technology in June of 1972 with a Bachelor of Electrical Engineering degree. He began his 45 year career in power engineering with The Okonite Company as a Research Engineer in the High Voltage laboratory until October of 1978.

- 10:45AM – 11:15AM – “Latest Development for HV AC Cable Accessories – challenges and trends” Ruben Grund, PFISTERER
Power requirement and therefore distribution is changing. Urbanization leads to new structures and the integration of electricity generated by renewable sources require new concepts and an optimized infrastructure. This paper describes these challenges and possibilities solving them. The need for a higher transmission capacity is obvious, nevertheless there are physical restrictions. Increase of conductor cross section is not only limited by transportation and cable laying but mainly influenced by the skin effect. Cable manufacturers have developed different approaches to reduce this effect. One option is to optimize the conductor segments by insulating them from one another, another Option is insulation of every single wire of a conductor which is then a so called “enameled conductor”. These optimizations offer clear advantages in reference to current carrying capability but connection of such a cable is difficult. The electrical contact requires every single wire to be connected whereas overall size of the contact element is critical. A possible solution is a front surface connector which will be discussed in further detail in the paper. Furthermore qualification and testing in reference to applicable standards will be discussed.
Nowadays maximum voltage level for AC network is at 550kV. Accessories are available and being used. Cable Terminations as a connection to an Over headline and Cable Joints to interconnect cables. A new approach is taking the pluggable system into this voltage range. By using the pluggable system a gas or oil -filled environment and the cable is being separated. This under mechanical and thermal considerations. Furthermore separation does not only allow cables to be connected but also usage of pluggable bushings. These pluggable bushings consist of RIP (resin impregnated paper) or RIS (resin impregnated synthetic) active part and a connecting system similar to the pluggable system. Usage of this system allows emergency and temporary use adding additional requirements in view of testing and operation.
Ruben Grund (M,80’) holds a electrical engineering degree from the University of Applied Science. He started his career in the Automotive industry performing car measurements. 2006 he changed into the field of Power distribution and transmission being a Project Manager at international projects. 2008 he became Product Manager for the High Voltage pluggable system (CONNEX). Since 2013 he has been heading the Technology department of Cable Accessories, which includes development, research, product management and a high voltage test lab.

- 8:40 – 9:05 AM – “Introduction of very large aluminum conductors in The Netherlands,” by Lawrence Lamballais, Prysmian Netherlands B.V.
The highly urbanized western part of the Netherlands (i.e. the Randstad conurbation) produces a large and growing amount of electricity, but is also a major importer of electricity (among others via the subsea cable between the UK and the Netherlands). To assure a reliable grid, the national transmission network requires a new 380 kV high-voltage connection between Rotterdam and Amsterdam. The construction is ongoing since 2006 and includes a major undergrounding of existing 150 kV overhead lines and constructions of several new intermediate substations.
The last part of the project exists of the installation of a 36 miles 380 kV connection near Amsterdam Airport of which 5,8 mile is installed underground using 12 cables with 6,000 kcmil and 7,000 kcmil aluminum conductors instead of the traditional copper conductors 4,000 kcmil and 5,000 kcmil. The Netherlands have almost 40 years of experience with the use of aluminum conductors up to 5,000 kcmil in XLPE (E)HV cables up to 380 kV.
- 9:05 – 9:30 AM – “Diluent for Use in Rejuvenation of Large Cables,” by Jason McCary, Novinium
Pursuant of strategies for mitigating the risk of supersaturation in cable rejuvenation, this report evaluated nine materials as diluents for large cables: a mixture of functional silanes (CB), dimethyl silane fluids (5CS and 10 CS), 2-heptanone (MAK), ethoxybenzene (PhOEt), dioctyl ether (Octyl2O), Aromatic 200, diethylene glycol dibutyl ether (BuDG), and tetraethylene glycol dimethyl ether (TG). Solubility of MAK, PhOEt, Octyl2O, Aromatic 200, and BuDG in polyethylene was too high to allow their use as diluents. CB, 5CS, and 10CS exude very slowly, even at 70°C. TG exudes slowly at 24°C, but diffuses out much more rapidly at elevated temperatures, addressing an issue of liquid remaining in a cable long after treatment. CB, 5CS, and 10CS gave two phase systems when they were mixed 50:50 with 732/80, eliminating them as potential diluents; however, TG produced a homogeneous solution with 732/80 before and after hydrolysis. The viscosity of TG is lower than 732/80, which improves the flowability of the fluid.
- 9:30 – 9:55 AM – “Bergen Linden Corridor Project (BLC),” by Dennis Johnson, POWER Engineers, Inc.
This presentation will discuss the challenges associated with the PSEG Bergen – Linden Corridor UG project. This project consists of installing 20 miles of duct bank for a 345 kV cable in a very urbanized area.

- 10:15 – 10:40 AM – “Non-Cementitious Thermal Grout (No-SetTM) for Underground High Voltage Transmission Lines,” by Ron Halderman, Mears Group
As a part of a record-setting installation The Mears Group was tasked with designing, engineering and installing thermal grout in the annular space around four 10-inch HDPE cable conduits inside a 30” ID fusible PVC casing pipe. Due to the length (7020 feet) and very challenging logistics, it was apparent that conventional cement-based grout would be difficult to effect “complete” fill while working under the relatively short “set up” time. A “tremie” method has generally been used to pump thermal grout into the annular space in shorter installations; however, “complete” fill is always a concern. As a response the project team elected to research and develop a thixotropic “non-cementitious” grout that did not have a critical time for installation. This presentation will outline the development path for this unique thermal grout and discuss the successful installation process.
- 10:40 – 11:05 AM – “Urban Applications of Superconductor Cables for Improved Capacity, Reliability and Resiliency,” by Michael Ross, AMSC
Utilities are under increasing pressure to increase capacity and reliability in urban environments. At the same time, costs for acquiring land and performing construction projects in those urban environments is skyrocketing while there is a growing demand that utility infrastructure be placed underground for aesthetic and security reasons. AMSC’s REG solutions can provide substantial relief to utilities that are faced with these challenges. REG systems allow utilities to move bulk power into and around urban areas using extraordinarily compact, underground, distribution voltage superconductor cables. While siting, permitting, and installing transformers and transmission voltage equipment is expensive and difficult within urban areas, REG solutions enable utilities to reduce the need for transmission voltage equipment and allow them to locate this equipment outside of the urban areas, substantially reducing project duration, disruption, and cost while improving system reliability.
- 11:05 – 11:30 AM – “Los Angeles Department of Water & Power – 138kV cable replacement project,” by Kishan Kasondra, Los Angeles Dept. of Water & Power
The LADWP’s Underground Transmission System originally contains approximately 70-circuit miles of underground 138-kV low-pressure oil-filled (LPOF) cables. These cables are located throughout Los Angeles from Wilmington to Brentwood. These cables were installed from 1943 to 1959. An increase in failure rates since 1986 indicates that these cables are deteriorating. The 138-kV Underground Transmission Cable Replacement Project (Project) requires removing aging 138-kV LPOF cable systems and installing new Cross Linked Polyethylene (XLPE) cable systems. This presentation will discuss how 45 circuit miles of cable is being replaced in 5 years, while increasing ratings and reliability.

- 4:15 PM – 4:45 PM – “In-situ Low Voltage Cable management strategy at a nuclear power plant environment” – Raihan Khondker, South Texas Project Nuclear Operating Company
Abstract: There are various options and guidance to test low voltage cable in a laboratory environment for forensics analysis. But, when it comes to in-operation testing, the options for low voltage testing are still not widely researched. There exists few available techniques through standards and industry research. It becomes progressively tougher to have test methodologies with no define acceptance criteria or test methodologies. The topic will cover some field experience information the techniques being used to perform condition monitoring at a nuclear power plant environment. The same techniques can be used as a model for environments where cables of such voltage class exist. The topics will cover several different tests and their methodologies and software based aging management trend modeling with the ability to define condition class of cables, data extrapolation from measured conditions and several other useful techniques.

- 2:10 pm – 2:40pm: “Condition Assessment of Pipe-Type Joints Utilizing Digital X-Ray Technology” by Arie Makovoz and Jade Wong of Consolidated Edison Co. of NY, and Stephen Halliwel of VJ Technologies Inc.
Most of Con Edison’s 800 miles of underground transmission cables comprised of High-Pressure Pipe-Type feeders. Joints of these types of feeders can move over time and, therefore, must be inspected periodically for sighs of damage or future failures.
In the past, conventional film x-ray has been used for underground transmission joint inspection. The radiation source was the radioactive isotope Cobalt-60, which requires special safety precautions and long exposure times. The film images were not clear enough to identify insulation or shielding defects and the chemical processing of the films required environmental controls.
The engineering and R&D team at Con Edison has demonstrated and qualified an innovative high energy digital x-ray system that can be used for non-intrusive, in-service inspection of high voltage underground transmission feeders. Digital x-ray imaging provides images with higher resolution and contrast sensitivity of the internal components of a joint to enable better assessment of its condition. The Con Edison team, working with VJ Technologies, has developed an optimal technique for imaging the high voltage underground transmission joints while minimizing the required inspection time.
Use of the digital x-ray technology in two cases resulted in the identification of incipient electrical failures. In one case a 345 kV joint was identified for internal inspection, and in the second case a 138 kV joint was identified for internal inspection. In both cases, after the joints were opened, extensive electrical damage was observed. It was verified that if these joints have been left in service, they would have experienced electrical failures.
- 2:40 PM – 3:10 PM “Advanced Fault Location Technique on HVDC Submarine Cables” by Chae-Kyun Jung, Korean Electric Power Company, Korea
Abstract : Fault location is the one of the significant aspects to protect HVDC submarine cables due to its special installation. Unlike conventional AC underground land cable, the system operator cannot check the status of submarine cable by visual inspection. Time domain reflectrometry(TDR) and frequency domain(FDR) are well known fault location methods and have been applied to various types of cable. However, the accuracy of them are limited clearly. The rise time and frequency sweep bandwidth affect the performance of each method, and both methods are vulnerable to noise. Also, the limitation are severer in application to submarine cable because of a long length of the cable.
In this presentation, an advanced fault location technique using time-frequency domain reflectometry(TFDR), is proposed to HVDC submarine cable systems. TFDR is hybrid technique which takes both advantage of TDR and FDR. It has better accuracy and robust to noise to signal distortion.

- 3:30 PM – 4:00 PM “First Permanent Monitoring System acquiring transients at 1MHz for a 380kV Transmission Circuit 40Km long”, by Mirko Melloni, Techimp HQ srl; The behavior of transients in high voltage cables is matter of concerns, especially when overhead lines alternates with cable links. For this reason, one of the leading power utilities in Europe, decided to have a “Power Connection Monitoring System” installed in one of their critical high voltage connection links.
This is a continuous permanent monitoring system capable of acquiring transients based upon amplitude thresholds. The purpose of the system is to collect evidences of the behavior of a combined transmission cable/overhead line and confirmation of the mathematical model in transient regime, and to obtain a possible indicator of the degradation of the system (residual lifetime) as a result of transients occurring in time.
This monitoring system is installed over a 40 Km high voltage power network in the North of the Netherlands, distributed in 8 Units (13 locations + 4 substations). The monitoring system is responsible for acquiring, processing, archiving and presenting information concerning the power connection and all functions defined are accessible for the user. The system is able to acquire continuous and impulsive voltages and currents, and raw PD waveforms that are stored in the local servers.
This presentation will review the key elements of the monitoring system, including sensors, instruments, monitoring software and hardware, the communication system among units, commissioning and installation. It will also describe technology for transients with examples of acquisitions
