Short circuit loop measurements:
- nominal voltage of the network: 115/200V, 127/220V, 220/380V, 230/400V or 240/415V with frequency 45...65Hz
- short circuit loop impedance measurement with 15mA current and resolution 0,01Ω without tiggering RCD
Testing AC, A residual current circuit breakers
- testing of standard and selective RCDs for the rated current values 10, 30, 100, 300, 500 and 1000 mA,
Low voltage resistance, continuity of equipotential bondings and protective conductors measurements.
- measurement of continuity of protective conductors with >200mA current in two directions
- compensation of the resistance of the test leads - possibility to use any lead
Phase sequence test.
Measurement and logging of AC voltage and current, frequency and power using additional clamp.
Memory of the results of measurement 990 cells, 10000 records.
Short circuit loop impedance measurement ZL-PE, ZL-N, ZL-L
Measurement using 23/40A current measurement range in accordance with
