High voltage apparatus HVA-70 is used for insulation testing of power cables and solid dielectrics by rectified voltage, as well as for solid dielectrics sinusoidal voltage (50Hz frequency) testing. This device is performed as two portable units – high voltage unit (HVU) and control unit (CU), connected via cable. Digital indication of test results is a notable feature.
