IEEE Unapproved Draft Std PC62.11a/D9E, Sept 2007 IEEE Draft Standard for Metal-Oxide Surge Arresters for Ac Power Circuits (> 1 kV) - Amendment: Short Circuit Tests for Station, Intermediate and Distribution Arresters (Amendment to IEEE C62.11-2005)
Institute of Electrical and Electronics Engineers (IEEE)
Scope
This standard applies to metal-oxide surge arresters designed to repeatedly limit the voltage surges on 48 Hz to 62 Hz power circuits (>1000 V) by passing surge discharge current and automatically limiting the flow of system power current. This standard applies to devices for separate mounting and to those supplied integrally with other equipment. The tests demonstrate that an arrester can survive...
