GL7101
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.
