Abstract
The article considers common zero-sequence current transformers of different manufacturers, assesses their amplitude and phase errors. Analyzes the possibility of their application to determine the malfunctioned feeder for single-phase earth faults using algorithms based on the calculation of the instantaneous powers of the zero sequence. Justifies the necessity of replacement of obsolete zero-sequence current transformers with modern ones for designing modern centralized earth fault protection.
