摘要

本文以不同厂家常见的零序电流互感器为例，对其幅相误差进行了评估。分析了用基于零序瞬时功率计算的算法确定单相接地故障馈线故障的可能性。论证了在设计现代集中接地故障保护装置时，将旧的零序电流互感器替换为现代零序电流互感器的必要性。

The Analysis of Possibility of Applying Current Transformers of Zero Sequence of Different Manufacturers Fordesigning Damaged Feeder Identification Systems

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.
