Abstract
The present invention discloses a system and method for leakage current protection. The leakage current protection method comprises the following steps: using a first control signal to control a first relay to be short circuit so as to generate a leakage current; a leakage current sensor generates an AC signal when the leakage current sensor detects the leakage current; using a leakage current signal processor to convert the AC signal to a DC signal; and when a latch circuit receives the DC signal, the latch circuit uses a second control signal to disconnect a second relay which is connected to electrical appliances which are needed to protect.
