Application of Line Surge Arresters for Switching Over-voltages in UHV Transmission Systems

ABSTRACT: Switching overvoltages (SOV) are critical for systems operating at Ultra High Voltage (UHV) level. Pre-insertion resistors (PIR) are usually used to suppress the switching overvoltages in UHV systems. PIR are effective in suppressing SOV’s, but their shortcomings prompt utilities to explore other protection schemes.  In this paper, the application of line surge arresters (LSA)...

What leads to the failure of distribution class surge arresters and how to prevent it?

Abstract—In the distribution system, surge arresters are less expensive compared to the other electrical equipment installed and their presence in the system goes unnoticed during the normal operation. Surge arresters are noticed only when they fail or when other system equipment fails. Distribution system surge arrester failure is interpreted in various different ways by utilities...

Switching over-voltages in UHV systems.

Abstract: Switching overvoltages (SOV) are of concern in transmission networks operating at Ultra High Voltage (UHV) levels. This paper addresses the switching transients when a long UHV line (1200 kV) is charged. The highest switching transients occurring due to the closing/reclosing of the circuit breaker connecting the transmission line were computed using the Electromagnetic Transients...
