I will be travelling to Bangkok, Thailand to speak at INMR World Congress 2023. I will be speaking on the Application of Line Surge Arresters to suppress Switching Overvoltages for UHV Transmission Systems. INMR world congress will be a conglomeration of technical experts, manufacturers and researchers in the field of high-voltage insulation engineering. It will... Continue Reading →
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 →
Had an opportunity to speak at AICTE Sponsored Two Week Online Faculty Development Program (Phase-I) on “Advanced Power Electronic Applications in Power Systems” (APEAPS-2020) organized by Department of Electrical and Electronics Engineering, Sasi Institute of Technology & Engineering (Autonomous), Tadepalligudem, Andhra Pradesh, India from 19/10/2020 to 31/10/2020. brochure-for-phase-1Download
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...

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...

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 →
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...

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...
