About HV Test Sets

The CIE/5050A is an AC high voltage test set providing a continuously variable output from 0 to 5 kV for HV withstand testing (hipot testing) of cables, switchgear, transformers, bushings, and other electrical equipment. The output voltage is monitored by a built-in analog voltmeter, and the instrument includes a trip mechanism that automatically disconnects the HV output when the relay under test operates — providing an important safety feature during dielectric withstand testing.

AC high voltage testing is used for acceptance testing of new equipment, periodic maintenance testing per IS/IEC standards, and fault investigation on installed cables and apparatus. The CIE/5050A is suitable for testing cable insulation at rated voltage, verifying the dielectric strength of transformer oil and solid insulation, and commissioning HV switchgear.

CIE supplies HV test sets to electrical contractors, power utilities, cable manufacturers, switchgear manufacturers, and commissioning companies across India — in Kolkata, Howrah, Bhubaneswar, Bangalore, Chennai, Hyderabad, Mumbai, Delhi, and across all regions where HV electrical infrastructure is installed and maintained.
