GB/T 18216.3-2021
ActiveElectrical safety in low voltage distribution systems up to 1 000 V a.c. and 1 500 V d.c.—Equipment for testing, measuring or monitoring of protective measures—Part 3: Loop impedance
交流1000V和直流1500V及以下低压配电系统电气安全 防护措施的试验、测量或监控设备 第3部分：环路阻抗
Application Summary AI generated
This standard specifies requirements for equipment used to measure loop impedance in low voltage distribution systems up to 1000V AC and 1500V DC. It is applied by electrical test engineers and safety inspectors to verify the effectiveness of protective earthing and bonding measures, ensuring that fault currents are sufficient to trigger protective devices like circuit breakers. The standard is relevant for testing in industrial, commercial, and residential electrical installations.
