IEEE 978 1984 Edition, January 1, 1984 Guide for in-Service Maintenance and Electrical Testing of Live-Line Tools
More info
Description / Abstract:
This guide provides recommendations for in-service inspection,
maintenance, and electrical testing of liveline tools. It is not
intended to include all of the proven practical methods and
procedures. However, these selected comprehensive recommendations
are based on sound engineering principles, engineering safety
considerations and decades of testing, and Þeld experience by many
utilities.
Only the electrical aspects are discussed, namely ac, dc, high-potential test, and Watts-Loss procedures. All electrical values throughout this guide, unless otherwise stated, are 50 Hz Ð 60 Hz rms values. Equivalent dc values as established by the user may be substituted.
Two main areas of this guide are inspection and testing: Section 4Ñat the job site, and Section 5Ñin the shop laboratory. Therefore, procedures are outlined from the very basic areas to the more exacting.
Purpose
To present in one document sufÞcient details of presently used methods and equipment to enable the in-service inspection, electrical testing, and maintenance of live-line tools.
To direct attention to appropriate standards or other documents relating to the care and testing of tools.
It is not intended that this guide should replace present proven utility standards or imply that these recommendations are superior to existing practices and, therefore, should be universally adopted as utility standards. This compilation of many accepted practices is presented speciÞcally in the form of a guide to be used by those utilities that are seeking guidance in establishing methods and procedures for maintenance and electrical testing of live-line tools.
This guide is not intended nor should it be considered as establishing a standard for maintenance and electrical testing of live-line tools in the electric utility industry.
