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)... Continue Reading →

FAULT IDENTIFICATION IN POWER CABLES BY USING TRAVELLING WAVE BASED APPROACH
Abstract: The faults in the underground cables cause to generate transients which propagate along the power cable as travelling waves. The velocity of the generated travelling wave and the time taken by a wave to reach the source point from the fault location enables us to calculate the fault distance value. In this paper a...

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...
