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 →

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...

Surge Arresters for Ultra High Voltage Transmission System – A Review.
Abstract—Extensive research on the Ultra High Voltage (UHV) Technology has been carried out in countries like Italy, the United States of America, Russia (the former USSR), Japan, and China. In this paper features of the UHV systems developed by various utilities are discussed. Insulation Coordination studies are essential to compute the overvoltages on the system... Continue Reading →
Neutral grounding reactors for shunt compensated EHV transmission lines
Abstract: Single Pole Reclosing is a widely accepted practice for improving the transient stability in EHV transmission systems. Successful single-phase reclosing requires some means of ensuring interruption of the secondary arc currents produced by capacitive and inductive coupling with the two energized phases of the same circuit or with the parallel circuit in case of...

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...
