Direct earth detector and system connecting generating device using it

A temperature sensor (50) detects temperature on a zero-phase current transformer or ambient temperature in the vicinity of the zero-phase current transformer. A microcomputer (17) corrects the current difference output from the zero-phase current transformer based on the detected temperature. An in...

More Information
Summary:A temperature sensor (50) detects temperature on a zero-phase current transformer or ambient temperature in the vicinity of the zero-phase current transformer. A microcomputer (17) corrects the current difference output from the zero-phase current transformer based on the detected temperature. An independent claim is also included for a system-interconnected generation device.
