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)…

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…
