3032: Survey of Existing Multi-Criteria Substation Equipment Asset Management Methods

The objective of this project was to identify and evaluate the performance of Multi-Criteria Decision-Support (MCDS) tools and methods, which have been successfully used by electrical utilities and similar entities to make optimized decisions on continued operation, restoration, refurbishment, replacement, and run-to-failure policies for utility equipment, specifically substation assets.By means of a literature search and critical review, a focused survey and follow-up interviews with users of M

3088: Use of Microprocessor-Based Relays in Stations

Microprocessor-based protective relays are able to provide additional functionality beyond their primary purpose of power system protection. They measure and record power system parameters that may contain information about the condition of the assets that make up the power system, and this information may be helpful in managing these assets. This report identifies the ways in which modern protective relays can help manage assets effectively, and assists asset managers in deciding how to maximiz

30102A: Evaluating the Advanced Substation Monitoring Capabilities of Digital Fault Relays, Fault Recorders, Power Quality Monitors, and PMU Equipment

Substation monitoring is advancing rapidly through the use of new devices and enhanced capabilities. Many types of advanced equipment have overlapping functions for addressing utility needs. Substation measurements are critical for utilities, since monitoring equipment is typically only installed at these locations. Standard applications of this equipment include determining fault location, responding to customer complaints, power quality trending and system disturbance investigation, while more

30132: Station Battery Condition Assessment for NERC PRC005-02 Compliance using Automated Remote Monitoring Technology

Several self-acclaimed NERC PRC005-02-compliant commercial battery monitoring/management system (BMS) are available in the market to meet or exceed automated data gathering, monitoring, and alarming requirement. CEATI launched project T193700-30132 to gain practical information for utilities to consider an automated monitoring system, and to review what supplementary information should be gathered to meet the NERC PRC-005-2 requirements. For this project, Powertech conducted a utility survey to

30116: CPF: Guide to Risk Management for Station Equipment and Apparatus

This project’s main objective is to develop a useful guideline for the risk management of substation equipment to address various challenges and uncertainties facing utilities. The project consists of three major tasks: 1) Performing a literature review of relevant published papers and documents, evaluating the models, methodologies and tools that are currently used in risk management for station equipment and apparatus, and assessing their benefits and limitations in power system applicat

3057B: Ethylene Production in Power Transformers: Phase II

This study deals with the gassing trend of the dissolved-in-oil analysis of three single-phase transformers built in 1997. The history of the gas generation development in these three free-breathing transformers showed that ethylene and carbon dioxide were produced progressively under normal operating conditions without simultaneous generation of hydrogen and other hydrocarbon gases. The ethylene and carbon dioxide gases have risen slowly and continuously in all three units since 1999, i.e. two

3022: Transmission Stations and Transformers - Fire Protection and Prevention

Utility members across both Canada and the United States took part in a multipart study, starting with an online survey in which information was collected on various fire protection practices for transmission substations operating above 44 kV. Follow-up site surveys were conducted at nine of the utilities to obtain additional insight on current industry fire protection methods for indoor substations, outdoor oil-filled equipment, and relay buildings. An analysis of major Canadian and United Stat
