TECHNICAL DATA

Earth Leakage Detector

Description

The FA2803 is a semiconductor integrated circuit with

amplifier for a high speed earth leakage circuit breaker

The FA2803 circuit for the amplifying parts of earth

leakage circuit breaker consist of differential amplifier,

latch circuit and voltage regulator.

It is connected to the secondary node of zero-current

transformer (ZCT) which detects leakage current in the

both input of the differential amplifier.

Signals amplified by differential amplifier are integrated

by an external capacitor, and connects to the input

terminal of latch circuit with output suitable for the

characteristics of high-speed earth leakage circuit

breaker. Latch circuit keeps low in the output till

the input voltage reaches the fixed level, and output

becomes high when the leakage current is greater than

some level. It drives a thyristor connected to the

output terminal of latch circuit.
