High-current loop impedance meter MZC-320S

High-current loop impedance meter



Measurement of very low short circuit loop impedances (with resolution 0,1 mΩ) with a current of 130 A at 230 V; maximum 300 A at 550 V or with a current 24 A at 230 V, maximum 30 A at 550 V (with resolution 0,01 Ω)

measurements in installations with rated voltages between: 110/190 V, 115/200 V, 127/220 V, 220/380 V, 230/400 V, 240/415 V i 290/500 V and frequencies 45…65 Hz,
ability to perform measurements in short circuit system: phase-phase, phase-protective, phase-neutral,
differentiation between the phase voltage and the inter-phase voltage while calculating the short circuit current,
ability to change the length of test lead,
four-pole method, test leads do not require calibration (measurement with current 300 A).
