          Recommendations for in-service inspection, maintenance, and electrical testing of live-line tools are provided. Both job-site and shop or laboratory procedures are covered. Only the electrical aspects are discussed, namely, ac, dc, high-potential test, and watts-loss procedures. All electrical values, unless otherwise stated, are 50 Hz--60 Hz rms values. Not all of the proven practical methods and procedures are included. However, the choice of methods is based on sound engineering principles, engineering safety considerations, decades of testing, and the field experiences of many utilities.<br />\n

          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 field experience by many utilities.<br />\n
          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.<br />\n
          Two main areas of this guide are inspection and testing: Section 4--at the job site, and Section 5--in the shop laboratory. Therefore, procedures are outlined from the very basic areas to the more exacting.<br />\n
          To present in one document sufficient 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, thereefore, should be universally adopted as utility standards. This compilation of many accepted practices is presented specifically 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.

          This guide provides recommendations for in-service inspection, maintenance, and electrical testing of liveline tools.

However, these selected comprehensive recommendations are based on sound engineering principles, engineering safety considerations and decades of testing, and field experience by many utilities.<br />\n
          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.<br />\n
          Two main areas of this guide are inspection and testing: Section 4--at the job site, and Section 5--in the shop laboratory. Therefore, procedures are outlined from the very basic areas to the more exacting.<br />\n
          To present in one document sufficient 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, thereefore, should be universally adopted as utility standards. This compilation of many accepted practices is presented specifically 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.

          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.<br />\n
          Two main areas of this guide are inspection and testing: Section 4--at the job site, and Section 5--in the shop laboratory. Therefore, procedures are outlined from the very basic areas to the more exacting.<br />\n
          To present in one document sufficient 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, thereefore, should be universally adopted as utility standards. This compilation of many accepted practices is presented specifically 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.
