Multifunction Tester COMBI521
Multifunction tester for electrical installation safety tests, power quality analysis and EVSE safety tests
COMBI521 carries out tests on electric systems in compliance with IEC/EN 61557-1 and therefore measurements of continuity of the protection cable, insulation resistance (with calculation of PI and DAR), overall earth resistance, RCDs type B, A and AC tripping time and current, line / fault impedance with calculation of prospective short circuit / fault current, phase sequence and conformity. COMBI521 also allows measuring and saving environmental parameters (illuminance, temperature), leakage current and electric quantities such as voltage, current, power factor, power and harmonics on single-phase systems. In combination with EV-TEST100, COMBI521 performs verification and control of electric car charging stations (EVSE) in accordance with IEC / EN 61851-1 and IEC / EN60364-7-722 standards.
