Injection Device Choices Paper

Injection Device Choices for Rejuvenating Cables

October 24, 2017

The choice of injection devices to deliver rejuvenation fluid to aging cables has changed considerably over the past few decades. This paper tells a brief history of devices relative to how cable rejuvenation processes have evolved beyond unsustained pressure rejuvenation (UPR) toward improved unsustained pressure rejuvenation (iUPR), and sustained pressure rejuvenation (SPR), examines the injection devices and terminations utilized for modern rejuvenation, and discusses the advantages and limitations of each device type.

Rejuvenation Upgrade Paper

Rejuvenation Upgrade

October 19, 2017

The case for a rejuvenation upgrade is even more compelling than the original case for treatment. Thirty years of experience all but eliminate the technology risk. A cable’s neutral condition has a baseline measurement which can be compared to the current condition. This comparison allows accurate extrapolation to future periods. Next-gen fluids are designed to deal with all significant aging mechanisms including ephemeral partial discharge. A cable’s suitability to be treated is pre-established. Early field results will be reviewed.

Better Next Year

May 12, 2017

The work presented in this paper utilizes very large data sets to compare the post-installation reliability of rejuvenation and replacement. The results shed light upon off-line partial discharge diagnostic testing. Either or both of the following propositions are true: (1) Electrical trees are rare and/or (2) rejuvenation adequately addresses electrical trees. Data to support both propositions are presented.

Modular Injection Component

November 1, 2016

The new Modular Injection Component (MIC) is the first cable accessory purpose-built and optimized for fluid injection. As well as enabling sustained pressure rejuvenation on energized cables, the MIC system further addresses several other limitations and shortcomings of current injection elbows.

Neutral Corrosion – Significance, Causes & Mitigation

August 30, 2016

This paper reviews six neutral corrosion issues and provides data to shed some light on the overall significance of the phenomenon. The paper draws upon IEEE 1617 and encompasses and expands upon the 1617 scope. This paper defines the purposes of the neutral, the consequences of excessive corrosion, the causes and chemical dynamics of neutral corrosion, dimensions the severity of the issue in North America, describes how to detect neutral corrosion, and provides options to address neutral corrosion once discovered. The paper also suggests areas for future work to provide guidance to circuit owners on the likelihood of neutral corrosion issues in their service territories.

How Hot Is It? A Survey of Temperatures Inside Medium-Voltage Electrical Enclosure Across North America

June 19, 2016

This paper studies the temperatures recorded inside electrical enclosures throughout North America. The results were collected over the course of a year at four geographically different locations in cryic, mesic, thermic and hyperthermic soils and from systems operating with phase to phase voltages of 15 through 35kV. This paper illustrates the effects that the ambient conditions, seasonal load fluctuation and installation factors have on the temperatures measured inside enclosures. The internal temperatures impact the safety and long-term durability of the ancillary equipment often contained within distribution-class electrical enclosures such as cable rejuvenation equipment, rejuvenation fluid, smart sensors, partial-discharges sensors, fault indicators, etc. and this data should be given consideration in the standards and installation guidelines for those devices.

What the Heck is Cable Rejuvenation?

October 14, 2015

If only we could do for humans what we do for underground residential distribution (URD) cables. Imagine that as you approached the end of your life, you could drink a magic elixir and within a week you could perform at your peak in every way for another 40 years. That is precisely what Novinium® brand Cablecure® rejuvenation fluid does for URD cables. Your power utility has another option, it can replace the aging URD cable with new cable. The new cable will perform reliably, but installing it will tear up streets and landscaping, take a lot longer, squander scarce world resources, and cost 2 to 5-times more, which must ultimately be reflected in your electric rates. Cablecure rejuvenation is a safer, faster, and better alternative.

Total System Reliability Program for Underground Electrical Distribution Networks

August 31, 2015

A holistic approach is proposed to look at all components of the system to ensure increased reliability with improved impulse breakdown strength, allowing the asset manager to retrofit an existing system to today’s stricter standards. This holistic approach looks at everything in the distribution system and once corrective actions are complete, the aged systems are completely updated to comply with the latest standards and thinking regarding reliability issues. The ultimate goal is to eliminate an unscheduled electrical outage.
