Description
Measuring instrument of a high voltage of direct and alternating current RD-140

Purpose of the RD-140 measuring instrument

It is intended for measurement of alternating sinusoidal voltage with a frequency of 50... 60 Hz to 100 kV and constant tension to 140 kV.

RD-140 provides measurement with high precision

  • the operating value of an alternating voltage with a frequency of 50 Hz, kV;
  • average value of constant tension, kV;

RD-140 can be used in testing high-voltage laboratories of an electrotechnical and power profile, and also research establishments.
