The High-Voltage Test-Set HVTS 5010 is designed for high-voltage testing of the electrical insulation of electrical equipment and electrical systems. Test voltage is adjustable up to 50 kV, 1 - 10 mA. The High-Voltage Test-Set HVTS 5010 mainly consists of a high-voltage transformer and a control unit. A motor driven variac generates the primary voltage of the high-voltage transformer. Output voltage can be selected from 2.0 to 50 kV with a voltage rise adjustable from 3 kV/sec to 50 kV/sec. Maximum output current is 10 mA. The output voltage is measured by a built - in capacitive voltage divider.
