LOOP/PFC/PSC TESTER

LOOP/PFC/PSC tester measures loop impedance, Prospective earth Fault Current (PFC), and Prospective Short circuit Current (PSC). These parameters are important for verifying that an RCD or protective fuse will operate reliably in the event of a fault. By measuring loop impedance, the current that would flow during an earth fault or short circuit can be calculated, which is utilized for appropriate selection of protective devices and confirmation of conformity to safety standards.
