EARTH LEAKAGE CURRENT DETECTOR

Description

The GL7101 is designed for use in earth leakage

circuit interrupters for operation directly off the AC

Line in breakers.

It contains pre regulator, main regulator, after

regulator, differential amplifier, level comparator,

latch circuit. The input in the differential amplifier is

connect to the secondary node of zero current

transformer.

The level comparator generates high level when

earth leakage current is greater than some level.
