High Current Short Circuit Loop Impedance Meter AMZC-310S

High Current Short Circuit Loop Impedance Meter AMZC-310S

The most important features of the AMZC-310S are

Measurement of very small short-circuit loop impedances (with resolution of 0,1mΩ) using the current of 150A under 230V, maximum 280A under 440V, or measurement using the current of 23A under 230V, maximum 42A under 440V:

  • Measurements on networks with rated voltages: 220/380V and 230/400V at 45...65Hz frequencies
  • Allows measurement on short circuit: phase-phase, phase-protection, phase-neutral
  • Distinction between phase and interphase voltage when calculating the short-circuit current
  • Allows to change the length of the measuring wires (measurement 23/42A)
  • Four-wire method, no conductor calibration required (150/280A measurement)
  • Measurement of the expected contact voltage or the shock contact voltage (with resistor from 1kΩ)
  • Measurement of alternating voltage 0...440V
  • Memory of 990 results and option to send them to the PC
  • Device meets the requirements of EN 61557
