Induced Voltage: A Major Risk Not Only During Live Working

Working in the vicinity of live parts is an effective working method on the high voltage power system. However, AC induction poses a threat to the linemen during vicinity working. The aim of this paper is to introduce the induction phenomenon on high voltage equipment, including the different coupling types, and also the magnitude of the evolving induced voltage and current. Moreover, a summary of accidents due to AC induction, their cause and outcome are also presented. One effective protection method against AC induction is the use of personnel protective equipment. For that purpose, some conductive clothing manufacturers developed specially strengthened garments against AC induction. The working philosophy of conductive clothing against AC induction is presented in detail, moreover the developed laboratory testing methodology is also discussed in this paper.
