• Light weight: 30 kg 60kV set

Safety features:

• Zero start high voltage output
• HV area interlocked
• Protection: a) Does not start if ‘Live, Neutral’ connected reversely. b) Does not start if ‘GROUND’ is open.
• Audio visual alarms at breakdown

System Description:
The system is semi-automatic. Test voltage is set on the digital display and test is started. The test voltage ramps to the set voltage level at 2kV per second [IS:6792/IEC 156/ etc]. In case insulation fails, the output test voltage is tripped and comes to zero. The stirrer starts to stir the oil for 60 seconds and stops automatically after 60 seconds. In case the insulation stands the set value, the test voltage remains for 60 seconds and automatically returns to zero. If during this period the insulation fails, the test voltage is tripped and output test voltage comes to zero.
