Switching overvoltages in motor circuits for petrochemical applications
Record of Conference Papers. Industry Applications Society Forty-Seventh Annual Conference. 2000 Petroleum and Chemical Industry Technical Conference (Cat. No.00CH37112), 2002The switching of HV motor circuits in the MW range can cause large overvoltages on motor terminals. The amplitude of the resulting voltage spikes depends on breaker and circuit characteristics. If the amplitude of switching overvoltages exceeds the BIL (basic insulation level) of the motor, overvoltage protection circuitry should be installed to ...

Switching overvoltage hazard eliminated in high-voltage oil circuit breakers
Electrical Engineering, 1943High-voltage transmission lines, when de-energized by conventional oil circuit breakers, are often subjected to high-voltage surges which present a real hazard to terminal equipment. The mechanism of surge generation is initiated by circuit-breaker restriking phenomena which are encouraged by the interruption of the large leading currents required to ...

Sensitivity Analysis of Maximum Switching Overvoltages in Three Phase Transformers
2018The objective of this paper is to perform the sensitivity analysis of maximum switching overvoltages in three phase transformers with considering changes in total winding capacity. Furthermore, a simulation subsystem model shown in Fig.1 for generation standard types of switching overvoltages (Fig. 2.) in the high voltage transformer has been developed
