Conversion of Intermittent Arc Fault Currents to Information Signals for Phase-to-Ground Fault Protection

  • Published:
Power Technology and Engineering Aims and scope

Conventional intermittent ground fault protections for electrical networks with isolated neutral have insufficient operation stability because they are based on the measurement of the current pulse peak. New methods of analog conversion of intermittent arc fault current pulses to normalized information signals are considered. The input signal must be converted before the analog-to-digital converter. The new analog conversion methods make it possible to improve the stability of protection without high-rate sampling.
