3003: Transformer Oil Leak Mitigation Program

This project evaluated various gasket materials with the goal of minimizing or eliminating gasket oil leaks from power station transformers. A series of tests were selected that were designed to provide information on material performance and actual sealing capability of these gasket materials under accelerated long-term service conditions. It examined the effectiveness of a range of oil-resistant and temperature-resistant gaskets materials. It became apparent that a wide range of performance ca

3066: Cascading Failure of Fuseless Shunt Capacitor Banks – Computer Modeling, Laboratory Testing and Remedial Action

Some utilities have experienced capacitor failures which resulted in cascading failures of other capacitors in the bank. Although the capacitors met existing standards there is suspicion the dielectric strength is not adequate when such failures occur. This report summarizes work done at the Bonneville Power Administration (BPA) to investigate the phenomena. A literature search is presented including peer reviewed publications and international standards as they relate to shunt capacitors. Compu

3094: Guide for Tender Evaluation, Design Review and Factory and Site Acceptance Tests for MV and HV Circuit Breakers and Switchgear

This guide provides a structured approach to the switchgear procurement process as an effective method of ensuring satisfactory operating performance in accordance with specified requirements. The foundation for the procurement process has been laid by previous CEATI projects which provided information on the technical aspects of circuit breakers and switchgear and assistance in the development of technical specifications. Guidance is provided on the complete switchgear selection and contract ad

3028: Evaluation of Online-Offline Techniques to Assess the Need to Replace CB Contacts for All Types (Oil, Air, SF6) of Circuit Breakers

This project was undertaken to evaluate various techniques for assessing the degree of wear of circuit breaker contacts to evaluate the need for their replacement. The techniques available include both online (i.e., monitoring) and offline techniques. The project’s approach was to focus on those methods that are commercially available today and those that show promise of being commercially viable in the near future. A survey was undertaken to help identify systems and techniques of interes

3062: Condition Based Risk Management (CBRM), A Process to Link Engineering Knowledge and Practical Experience to Investment Planning

This report documents the application of the Condition Based Risk Management (CBRM) process to a sample of power transformers. The supplied asset data was used to develop a CBRM spreadsheet model that provides utilities with a complete set of results including the following.For each asset:A definition of the current condition as a Health Index (HI)An estimate of the current Probability of Failure (PoF)The ability to 'age' each asset to give an estimate of the future HI and future PoFA measure of

3078: Station Equipment Condition Parameters

This report presents the results of a bench marking survey prepared by the LCMSEA Interest Group of CEATI International. The survey is intended to identify the non-condition and condition based assessment indicators member utilities are using for condition assessment of station equipment including the relative weighting applied to each indicator used in their condition assessment programs.Assessing the condition of the equipment in a station is a crucial component of a utility’s maintenanc

3071: Development of a Predictive Analysis Program for Evaluating the Success of Reclamation of Mineral Based Transformer Oils

Reclamation of transformer oil is not only a costly undertaking, but in most cases requires an outage to some part of the power system. The purpose of the reclamation process is to extend the life of the entire insulation system critical to the operation of a power transformer. The benefits of the reclamation process do not only relate to the oil quality, but also to the effect poor oil quality can have on the delicate paper component of the insulation system of the transformer. It is critical t

30106A: Criteria for Spare Equipment and Parts - Phase I

In an increasingly competitive market space that has new and expanding regulatory paradigms, the need for utilities to effectively manage equipment and spare parts inventories has never been greater. To better understand the current practices within the industry, a survey of multiple utilities was conducted in order to examine failure rates, spare parts / equipment levels, and participation in inventory sharing programs. The survey focused on a representative subset of major equipment items in c

3098: Utility Asset Management Experiences and Best Practices

The objective of this project was to gather information pertaining to the asset management business model and related practices and processes used by electrical utilities, enabling utilities to learn from the experience of utilities worldwide. The report identifies proven approaches and tools that can be used in the development and implementation of superior asset management processes.Keywords:Asset Management, Implementation of Asset Management business model, ISO55000, Self-Assessment against
