Loop impedance measurement is important in preventing accidents caused by the earth leakage breaker and other protection devices to becoming inoperative. JavaScript seems to be disabled in your browser.

Kyoritsu 4120A loop impedance meter available from Test and Tag Supplies

Custom microprocessor controlled for highest accuracy and reliability. Measures low loop resistances resolution of 0. This advantage over many other loop impedance meters means there is no need to by-pass many RCD tyoes at distribution boards, when conducting Loop or PSC tests. This instruction 412a0 contains warnings and safety rules which must be observed by the user to ensure safe operation of the instrument and retain it in safe condition. The current will not cause tripping out involved RCD even the one with the lowest nominal differential current 30mA.


The RCD could trip during the tests also with model A. The cover can be detached and put on the back side of the main body during measurement. Kyotitsu occurs when the earth circuit is overloaded or shorted and sufficient current does into flow into the circuit where the loop impedance is too high. Kyoritsu A Loop Impendance Tester.
