3067: Substation Ground Grids—Additions and Modifications

Power delivery systems are in continuous evolution from load adjustments, network reconfiguration, supply additions, reliability requirements, regulatory directives, aging equipment, operating needs and new technology. Change to the power delivery system frequently initiates some form of substation project, and substation owners are challenged to identify if ground grid modification is needed, what the modification should be, and how to implement the modification in a safe and efficient manner.

30143: Guidelines for Spare Equipment Determination and Management

The determination and management of spare equipment – particularly substation infrastructure – represents an important but often overlooked component of a utility’s operations. In recent years, CEATI has conducted several surveys of its member organizations to identify the strategies they employ to determine and manage their spares and understand the general frameworks from which its constituents were working. Acknowledging that this sector of utility operations has advanced since this initial r

30133: Development of Reference Standard of RCM Worksheet for Substation Assets

Reliability centred maintenance (RCM) is a methodology incorporating structured decision-making support processes that focus on the optimization of maintenance tasks and intervals for assets, as defined in its operating context. It is a process that can be used to determine the failure management policy of any physical asset within a utility, such that useful life and reliability are increased while considering safety, environmental, economic, and operational consequences (e.g., SAIDI and SAIFI

3073: Review and Summary of Key Standards and Guides for Power Switchgear

In this report, the key standards related to high voltage power switchgear are identified and summarized. Key topics and sub-topics have been developed and are related to each of the summarized standards by the use of a relevance matrix. This review and summary of key standards and guides will help utility engineers in the selection of the appropriate standards and ratings to conform to their needs and specifications. It will enable them to judge which standard is most appropriate when specifyi

30128: Online Monitoring Partial Discharge Analysis of Substation Transformers

The purpose of this work was to discover the technical state-of-the-art relative to on-line monitoring of partial discharge (PD) in power transformers. A literature search was conducted to uncover any new technologies being developed that perhaps are not yet commercially available, particularly as it may relate to artificial intelligence or machine-learning techniques to identify and categorize partial discharge patterns. A survey was developed and shared with utility customers to discover their

3090: Selection and Specification Guide for HV Surge Arresters

The selection of appropriate overvoltage surge protection is a primary concern when providing insulation co-ordination of complex, costly systems and apparatus installed on the high-voltage network. The overall aim is to reduce the cost and disturbance caused by insulation failure and resulting system outages to an economically and operationally acceptable level. As the use of products and equipment vulnerable to voltage surges and spikes continues to increase, the requirement also increases for

3702: Soil Resistivity Testing

The design of a substation or line almost always includes resistivity testing, given that soil varies somuch between sites. Those who test resistivity tend to follow a routine procedure, even whendiversity is warranted. For example, a thick conductive layer over high resistivity bedrock requires aparticularly long distance between probes relative to the station length. Errors in resistivity data aredifficult to uncover and may become known only when commissioning the completed station.Especially

3097: Development of a Health and Risk Index Tool for a Station

Electrical utilities are under increasing pressure from regulators to justify the level and prudency of capital and maintenance expenditures on the electrical system. This report presents a methodology for assessing the overall condition of a station by combining the individual asset Health Index formulations with the evaluation of additional factors such as site selection, environmental conditions, power delivery, safety and operability. The methodology allows for the prioritization and justifi
