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: 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...

This paper was presented at the International Conference on High Voltage Engineering and Technology (ICHVET-2015)-January 29-30, 2015, Hyderabad. ABSTRACT: In order to utilize less Right-of-Way and efficient transmission of bulk power, India is set to establish a 1200kV AC power transmission system. The Right of Way requirement of a transmission line is defined by the... Continue Reading →

ABSTRACT: Transformer is a major component of the power system. In EHV and UHV class equipment, the design and testing of the insulation should be given highest priority. This paper deals with surge voltage distribution across the winding by considering various values of a ratio between shunt capacitance to a series capacitance of the winding... Continue Reading →
