3282: Transmission Line Failure Investigations – Guidelines for Collecting Incident Data and Evidence

When failures of overhead transmission lines (OHTL) occur, the opportunity to collect information and materials that would be invaluable for assessing the causes and improving engineering, construction, and asset management processes is often lost as crews seek to restore and reenergize failed facilities. This loss is in part due to a lack of consensus understanding among utility personnel – including first responders – regarding the value of collecting failure event information befo

3209: Use of a Leakage Current Monitoring System for Pollution Monitoring on Overhead Lines

The purpose of this project was to determine whether leakage currents give an indication of the insulators’ level of contamination, and if so, to develop an algorithm which would determine the insulators’ contamination conditions.Keywords: Leakage current, partial discharge

4102: Control of weeds in electrical facilities such as substations, switchyards, capacitor stations, and cable termination sites

Industrial site vegetation management (ISVM) is performed in and around electric facilities, such as substations, powerplants, pole-yards, solar installations, and wind generation, as well as a myriad of other infrastructures such as oil, gas, highways, and railroads. The square miles(km) of non-paved land maintained by ISVM are unknown but these sites are collectively substantial and ubiquitous across populated areas of North America. The study included a review of related literature and a surv

7071: Energy Management Best Practices for Cannabis Warehouses and Greenhouses

The legalization of recreational cannabis in Canada and some US states has generated a new sector with significant energy needs. This budding industry is creating a need for policymakers and utilities to better understand the energy requirements of the sector and find ways to manage demands on energy systems.The objectives of the study are twofold: to assess and document baseline consumption of electricity and natural gas for cannabis warehouse and greenhouse operations, and to document best pra

3722: Improvements to Fall of Potential Ground Testing

Fall of Potential (FOP) testing for measuring the ground impedance of station grids is described in IEEE Std 81. It requires the remote current probe C2 to be placed at least five times the largest grid dimension from the centre of the station. The potential probe P2 may be located in line with C or in the opposite direction. Locating P2 at 61.8 % of the distance to C2 in the same direction provides the correct ground impedance when (a) soil resistivity is uniform, (b) there are no external inte

3142: Survey on Practices for Integrating Battery Storage into a Power System

This report describes the main tasks undertaken by the investigators between March 24, 2021, and September 8, 2022, during the Know BESS (Battery Energy Storage System) project development. During the first year of project development, considerable efforts were undertaken to review the literature on battery storage systems and their applications at the utility-scale level. These efforts contributed to the contents of the literature review on the BESS supply chain (Item 5), which has two essent

3136: Best Practices for Compliance with NERC Standard TPL-001-004 “Transmission System Planning Performance Requirements"

Best practices are provided herein for Utilities to fulfill compliance with NERC TPL-001-4 Reliability Standard requirements. The identified best practices were derived from a wide sampling of Utilities. The NERC TPL-001 Reliability Standard was written to promote improvement in the reliability of the Bulk Electric System. This report presents the additional requirements from version 4 of the Standard and the process followed by Utilities to show compliance with TPL- 001-4, which is generally do

3908: End of Useful Life Assessment Guide for Protection Systems

This project presents a generic methodology for determining the expected end of life (EOL) for different types of protection system assets using the inputs that are typically available from utilities and asset degradation curves. This provided quantitative metrics for interpreting an asset’s effective age.Asset degradation curves were derived for different types of devices in protection systems, based on industry practices, input from utilities’ subject matter experts (SMEs) and hist

3014: Development of a Life Assessment Method for Insulation System Conditions in Power Transformers

In recent years, new diagnosis and monitoring techniques have been developed for insulation condition assessment, but their sensitivity to aging and their potential for predicting residual life is still to be demonstrated.To respond to these issues, we examined the potential of two electrical methods (the Recovery Voltage Method and the Tan(Hz) measurement) to sense aging and how their signatures can be related to transformer age and condition.The study covers the evaluation of twenty transforme

0243: CPF: Understanding the Incident Command System – Guidance to Dam Owners/Operators

This document introduces dam owners to the Incident Command System (ICS), which they may find themselves working in during an emergency. Understanding the reasoning and function of ICS will increase a dam owner’s efficiency and effectiveness when working with emergency responders. This document focuses on the ICS developed in the United States (commonly in use in North America). There is a need for common terminology when communication between dam owners/operators and the emergency respons
