RCD and network resistance meter PZF-300

Measurement of the impedance of the "phase-zero" and "phase-phase" loops with the calculation of active and reactive resistances.

Calculation of the predicted short-circuit current of the phase-to-neutral and phase-to-phase loops, reduced to mains voltages of 220/380 V, 230/400 V or 240/415 V.

Measurement of parameters of residual current devices (RCD) of general and selective types, which are under voltage, with the following parameters of differential current:

- for types AC, A and B on a sinusoidal current with the ability to set the initial phase of the current 0 º and 180 º;

- for types A and B on pulsating direct (single-wave) current, on pulsating direct current with a current phase delay angle of 90 º and 135 º with the possibility of setting the current polarity.

AC voltage measurement.

Measurement of the touch voltage during the flow of the rated differential current of the RCD (requirement of GOST IEC 61557-6-2013);

DC resistance measurement (metal bond).

Calibration interval 2 years
