An investigation of sensitivity of a phase-shift method for faulty phase determination of protective shunting control in a mine electrical system (English)
0 references
A ground leak sensitivity bound is determined using the phase-shift method for the faulty phase determination in 380-1140 V electrical systems. The maximum null point grounding resistance that still allows protective shunting control is defined. Practical recommendations on the choice of the leak currents protection device parameters are given.
