MZC-310S short-circuit loop impedance meter with calibration certificate WMPLMZC310

The MZC-310S meter, in addition to measurements in receiving networks (for short-circuit loop impedance measurements, a resolution of 0.01 Ω is sufficient), offers short-circuit loop impedance measurements with a resolution of 0.1 mΩ; which allows for accurate measurement also in circuits where very high values of short-circuit currents may occur (in distribution and receiving networks protected by high-current circuit breakers). The accuracy of the measurement is ensured by the four-wire method and the flow of the test current in the 150/280 A pulse.

Measurements of very low short-circuit loop impedance (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 o frequencies 45...65 Hz,
• the ability to measure in a short-circuit circuit: phase-to-phase, phase-protective, phase-neutral,
• distinguishing between phase and phase-to-phase voltage when calculating short-circuit current,
• four-wire method, no need to calibrate the test leads (150/280 A measurement),
• the ability to change the length of the test leads (23/42 A measurement).
