A Comparison of Rejuvenation Hazards

January 19, 2011

Over two decades have elapsed since the commercial introduction of the first solid dielectric enhancement technology or chemical rejuvenation. During those years, silane injection has proven itself as an important tool to enhance the reliability of aging infrastructure. There are some risks associated with rejuvenation. Some of those risks are shared with replacement. Some risks are unique to injection. This document examines the risks of chemical rejuvenation utilizing the two most widespread commercial injection methods and materials for URD cables.

Cable Rejuvenation: Choices

March 31, 2010

From 1984 through 2009, approximately 90 million feet of medium voltage underground power cables were treated with available injection technologies. Cable injection is typically a fraction of the cost of replacement and the economics are almost always in favor of rejuvenation. Undoubtedly, the favorable economics of rejuvenation fueled its rapid growth. Today, utilities can evaluate their cable rejuvenation choices to enhance power cable reliability at the lowest possible cost.

Considerations for Injecting Cables with High Conductor Temperature

November 11, 2009

The first generation of injection technology was intended for lightly loaded cables in cooler soils. Attempts to utilize this first generation approach for more heavily loaded cables in warmer climates, particularly feeder cables, have not always been successful. Formerly identified issues including, supersaturation, over saturation, asymmetrical penetration profiles, and aluminum corrosion are reviewed. A previously unidentified failure cause is described. A new generation of injection technologies that addresses all of the identified postinjection performance issues is introduced.

Electrical Tests on Novinium 200 A Load Break Injection Elbows

August 26, 2009

Two modifications were recently made by Novinium to the Elastimold 200 A load break direct test elbow. This report shows the results of tests made to determine if modifications made by Novinium to the Elastimold direct test elbow interfere with the elbow’s compliance to the requirements set forth in IEEE 386, and to perform partial discharge and flashover tests on modified and non-modified elbows and to compare the results.

Silicone Injection: Better with Pressure

May 19, 2009

Moderate pressure injection has been utilized for over two decades and has demonstrated several significant advantages over the low pressure inject-and-soak paradigm. In 2006 sustained moderate pressure injection further advanced rejuvenation technology, increasing post injection reliability. This paper traces the evolution of injection pressure in dielectric enhancement technology and compares the merits of the available delivery methods. The paper goes on to introduce the latest improvement in injection technology, thermally enhanced rejuvenation.

RUS Letter Order Approving Capitalization of Novinium Brand Product

April 3, 2009

On September 4, 2008, the Federal Energy Regulatory Commission (FERC), acting upon a request from the manufacturer, issued Docket No. AC08-143-000, approving the capitalization of the cost of the injection rehabilitation products for underground cable (URD) known by the product names Perficio and Ultrinium, which are manufactured by Novinium, Inc. Based on the actions of the FERC, the Rural Utilities Service now authorizes the capitalization of the cost of Perficio and Ultrinium injected into underground cable.

Thermal Testing of Novinium Feeder Cable Splices on Service Aged 750kcmil XLPE Cable Extracted from the Georgia Power System

April 1, 2009

At the request of its members and with the assistance of Novinium Inc, NEETRAC has undertaken testing to determine the response of service-aged URD and Feeder cables to cable rejuvenation. This report describes thermal testing of Novinium Feeder Cable Splices on service aged 750kcmil XLPE cable extracted from the Georgia Power System using the procedures agreed upon by the NEETRAC members supporting the URD and Feeder project (07-136).
