Introduction This introduction is not part of IEEE Std C62.22-2009, IEEE Guide for the Application of Metal-Oxide Surge Arresters for Alternating-Current Systems. Abnormally
3、 high voltages can occur on power systems from a variety of origins, including lightning and switching. These overvoltages can cause insulation breakdown, resulting in equipment failure and interrupting the continuity of electric supply to users. Proper coordination of surge-protective devices with
4、the insulation strength of the protected equipment is essential to protect the reliability of power systems and equipment. Metal-oxide surge arresters are the predominately used overvoltage protective device on ac power systems. The application of surge protection devices and their coordination with
5、 equipment insulation strengths is a broad and complex subject for which the industry has accumulated a large body of knowledge, experience, and practices. This document provides a concise guide to the application of metal-oxide surge arresters to protect power systems and equipment operating at a n
6、ominal voltage of 1000 V and greater. This application guide does not cover the application of low-voltage surge protective devices below 1000 V alternating current (ac). However, it references these devices when applied to the secondary of a transformer because they are part of the transformer prot
7、ection. Step-by-step directions toward proper solutions for various applications are provided. In many cases, the prescribed steps are adequate. More complex and special situations requiring study by experienced engineers are described, but specific solutions may not be given. These procedures are b
8、ased on theoretical studies, test results, and experience. The clauses of this guide cover the various categories of electric power systems and equipment. Clause 4 provides fundamental information on overvoltages, metal-oxide surge arrester characteristics, and equipment insulation. Clause 5 covers
9、the application of surge arresters to stations and substations. Clause 6 covers application of surge arresters for protection of overhead and underground distribution system equipment, including all distribution transformers, and other electric distribution equipment. Clause 7 covers the protection
10、of overhead transmission and distribution line insulation, which is an application unique from station equipment and underground protection because the overhead line insulation is self-restoring. Clause 8 covers the protection of large electrical machines, including generators and motors, rated 1000
11、 V and above. This guide is a revision of IEEE Std C62.22TM-1997.aSubstantial reorganization of the guide has been made to help users focus on their areas of interest. Major additions to this revision include substantially increased information on the characteristics of surge arresters and surge arr
12、ester energy discharge considerations. Extensive overhead line protection guidelines have been added. a Information on references can be found in Clause 2. v Copyright 2008 IEEE.
