The KV30-40D Mk4 high voltage AC test set is a general purpose test instrument designed for testing insulation systems and the measurement of breakdown voltage on electrical plant and components.
The output voltage is variable up to 30kV. A zero-voltage interlock is provided, ensuring that the output may only be energised with the voltage control at zero. The output voltage and current are metered by large true RMS reading digital meters.
The unit features automatic mains voltage selection and an external 24VDC interlock circuit for connection of emergency-off switches and interlock switches on the test enclosure.
The test object and output are protected by an adjustable electronic current trip. The trip level may be set to 10-110% of the rated output in 10% steps.
Breakdown of the test object is visibly indicated and the unit must be manually reset after a trip condition before testing can be resumed.
An optional test timer can be provided for pre-selectable test times of 5 seconds to 5 minutes.
The unit is supplied in a compact, portable case with a permanently connected 2 metre long HV output lead.
