Ground fault circuit interrupter design

누전차단기의 설계와 제작

The hazards of electrical shock are well known, but the conventional ground fault circuit breakers did not provide the statis factory safety for human body. Thus this paper considers the standards of performance that they must meet, and describes the new tripping mechanism the operations and the improvements. The experiment at new G.F.C.I. indicates maximum tripping time 25msec minimum sensitive leakage current 25mA and maximum nonaperation leakage current 15mA.
