《GB/T 4876-1985交流高压断路器的线路充电电流开合试验》由TC65（全国高压开关设备标准化技术委员会）归口，主管部门为中国电器工业协会。
本标准适用于额定电压110kV以上50Hz交流高压断路器（其他开关电器可参考采用），在正常条件和接地故障条件下，线路充电电流开合试验。本标准亦适用于串有一段短电缆的架空线充电电流开合试验。

Scope

This standard applies to 50Hz AC high-voltage circuit breakers with a rated voltage above 110kV (other switching appliances can be used for reference), and the line charging current switching test is performed under normal conditions and ground fault conditions. This standard is also applicable to the charging current switching test of the overhead line with a short cable in series.
