Measuring instrument of a short-circuit current digital Shch41160

The measuring instrument of a short - circuit current Shch41160 is intended for measurement of a short - circuit current of a chain a phase zero in alternating current mains of 220 V, the frequency of 50 Hz with a glukhozazemlenny neutral and a phase shift of phases between tension and current (30±25) °. Is issued instead of M417.

Measurement of a real short - circuit current with restriction of time of course of a short - circuit current lasting not more than 10 ms is the basis for operation of the Shch41160 measuring instrument.

Technical datas

Measurement range of a single - phase current k. z. - from 10 A to 1000 A.

Measuring instrument power supply from the alternating current main of (220±22) B, with a frequency of 50 Hz.
