Combined arc fault circuit interrupter and leakage current detector interrupter

摘要: A combined arc fault circuit interrupter and leakage current detector interrupter. sensor, amplifier, comparator are employed to detect the presence of in alternating power conductors. Upon detection an amount beyond a threshold level, relay is opened, disconnecting source AC from conductor being monitored, such as appliance line cord. An envelope detector, microcontroller The algorithm implemented by capable discriminating between high frequency noise which not caused parallel or series fault, with anomalies result arcing.
