Possible measurements

Short-circuit loop measurement:

  • impedance measurement with 23 A current (44 A phase-to-phase) – short-circuit resistor R=10,
  • measurement range: 95…440 V, frequency 45…65 Hz,

Short-circuit loop measurement with resolution 0,01, in distribution network without tiggering RCD (In30 mA):

  • automatic calculation of short-circuit, detection of phase voltage and phase-to-phase voltage,
  • additional UNI-Schuko plug for automatic measurement, AGT adapter for 3 phase network measurement.

Testing of general and selective RCD with the rated differential current of 10,30,100,300,500 and 1000 mA. (Type AC, A and B).

Measurement of insulation resistance:

  • with test voltage 250 V, 500 V, 1000 V, 2500 V,
  • measurement range up to 10G,
  • automatic discharging after measurement,
  • automatic measurement of all resistances in 3,4,5-wire cables using optional adapter AUTO-ISO,
  • acoustic signals in 5 sec intervals for insulation resistance characteristic,
  • elapsing T1, T2, T3 times (0…600 s) form measurement of absorption coefficients (DAR, PI or Ab1, Ab2)
  • safety measurement – protection against overvoltage.

Measurement of earthing resistance.

Bi-directional testing of PE wire continuity using 200 mA current.

  • Autocalibration of test leads.

Phase sequence testing.
