Title:
ELECTRIC LEAKAGE BREAKER FOR A HIGH CHARGE CURRENT ELECTRIC LINE
Document Type and Number:
WIPO Patent Application WO/2011/049299
Kind Code:
A2
Abstract:
Disclosed is an electric leakage breaker that uses a leakage current sensor to detect a resistive leakage current flowing through an electric line as is, and to detect a capacitive leakage current (also referred to as a 'charge current') at a level reduced from the actual level, so as to reduce the occurrence of malfunctions caused by capacitive current leakage in an electric line, by reducing the detected leakage current to less than the actual capacitive leakage current in the electric line.
