IMPROVING THE EFFICIENCY OF FAULT PROTECTION SYSTEMS OF ELECTRICAL GRIDS BASED ON ZERO SEQUENCE VOLTAGES AND CURRENTS WAVELET TRANSFORMS

IMPROVING THE EFFICIENCY OF FAULT PROTECTION SYSTEMS OF ELECTRICAL GRIDS BASED ON ZERO SEQUENCE VOLTAGES AND CURRENTS WAVELET TRANSFORMS

Introduction. A significant proportion of earth faults in medium voltage networks represents a short-lived and transient process. Problem. In such cases, earth fault protection that responds to steady-state current and voltage is not able to operate properly. Purpose. To develop earth faults protect...
