Simulation of switching overvoltage in mine production unit
2017 IEEE Conference of Russian Young Researchers in Electrical and Electronic Engineering (EIConRus), 2017The problem of overvoltage is particularly important for underground coal mine electric power supply systems as degradation of insulation may lead to electric faults, power outages, fire and explosion of methane and coal dust. This paper is dedicated to simulation of overvoltage in vacuum circuit breaker caused by emergency deenergization of mine ...

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 ...

Phase-Phase Switching Overvoltages, Transmission Lines
2018Phase-phase insulation naturally occurs in stations—between buses and from one piece of equipment to another. Therefore the phase-phase strike distance and SSFOR should always be considered in station insulation coordination studies. A phase-phase insulation always exists with a phase-to-ground insulation.
