Purpose
The DTE–70/50D diode test unit is designed for:
- testing the insulation of power high-voltage electrical cables using rectified voltage with an amplitude value up to 70 kV.
- testing solid dielectrics with sinusoidal alternating voltage of industrial frequency up to 50 kV (RMS), e.g., high-voltage components of distribution equipment;
- laboratory and research purposes.
The DTE-70/50D model is a modernized version featuring digital indicators. Digital meters offer high accuracy, easy-to-read measurements, and a modern user interface.
You may also want to take a look at the DTE-70/50 — a version of the device with analog meters, or the DTE-70/50T — a new model with extended functionality.
The DTE-70/50D device is a modernized version of the AID-70/50 (AID 70/50) unit, designed for high-voltage testing of cable insulation and solid dielectrics.
