The digital first-harmonic detecting method based on this kind of filter can be used in anyone power harmonic compensation system and microcomputer relay protection system.
此滤波器设计的数字基波检测方法可用于任何一种电力系统的谐波补偿和微机继电保护系统中。

A study on an auto compensation of capacitance current should be highly conducted to improve the technical level of the leakage check relay.
但应努力开展电容电流自动补偿的研究工作，以进一步提高检漏继电器的技术水平。
