GB/T 18216.3-2021 Electrical 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
Abstract
This document specifies the requirements for loop impedance equipment between the measuring conductor and the protective conductor, between the measuring conductor and the neutral conductor, or between two measuring conductors. The measurement of loop impedance is carried out by loading the test circuit and measuring the voltage drop.
