Title: Method of overcurrent protection of electric installations
Inventor: AGAFONOV YURII MYKOLAJOVYCH
IPC: H02H3/08
Filed: 2003-01-30
Abstract: The present invention relates to methods for protecting electric installation against overload, short-circuits, and phase asymmetry. The proposed method of overcurrent protection of an electric installation implies using the algorithm for measuring effective values of phase currents with storing data in an intermediate memory, the result of which is a minimal length of measurement intervals and a possibility to average the measurement results in order to exclude accidental errors. The method is distinctive by measuring effective current values with a shift by the measurement period, determining the average current values, and checking the excess of the specified short-circuit and overload current set values in each phase circuit of the mains load. Additionally, the monitoring of the phase currents is possible for the disconnection of the electric installation when the phase current terminates. The proposed method provides a possibility to enhance the speed of response and noise immunity of devices for controlling automatic circuit breakers designed for disconnecting power consumers in emergency states.
