MZC-310S short circuit loop impedance meter Sonel

Measurements of very small short-circuit loop impedances (with a resolution of 0.1 mΩ) with a current of 150 A at 230 V; maximum 280 A at 440 V or measurements with a current of 23 A at 230 V, maximum 42 A at 440 V.

• Measurements in networks with rated voltages: 220/380 V and 230/400 V with frequencies of 45...65 Hz,
• possibility of measurement in a short-circuit circuit: phase-to-phase, phase-to-protective, phase-to-neutral,
• differentiation of phase and phase-to-phase voltage when calculating short-circuit current,
• four-wire method, no need to calibrate wires (150/280 A measurement).
• Possibility to change the length of measuring wires (23/42 A measurement),

Measurement of the expected touch voltage or the touch voltage of the flare (with a 1 kΩ resistor).
Measurement of alternating voltages 0...440 V.
Memory of 990 measurement results with the possibility of their transmission to a PC.
The instrument meets the requirements of PN-EN 61557.
