Directional detection of a fault in a network of a grounding system with compensated or insulated neutral point
In a voltage power system, especially a power system with a compensated or insulated neutral point, the positioning of a single-phase fault according to the present invention is based on that: the fault is detected through the change of a zero sequence voltage (V0); in a continuous fault condition,...

Summary: | In a voltage power system, especially a power system with a compensated or insulated neutral point, the positioning of a single-phase fault according to the present invention is based on that: the fault is detected through the change of a zero sequence voltage (V0); in a continuous fault condition, the phase difference is determined directionally, especially through the symbol of an angle or product between the derivative (dI0/dt) of the zero sequence voltage and the zero sequence voltage (V0). |
