T&R KV15-80D mk3 High Voltage AC Test System
The KV15-80D mk3 high voltage test set is a general purpose test instruments designed for testing insulation systems and the measurement of breakdown voltage on electrical plant and components.
The unit has an output voltage variable from zero to 15kV with accurate metering on both the output voltage and current. A zero-voltage interlock is provided, ensuring that the output may only be energised with the voltage control at zero. The output voltage is metered by a large, linear analogue instrument marked 0-12kV, 0-20kV and 0-40kV.
The KV15-80 has an x0.5 range on the voltmeter giving a full scale of 6kV ,10kV or 20kV respectively. Load current is metered by a second analogue instrument with a full scale of 100mA. The test object and output are protected by an adjustable 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.
The unit must be manually reset after a trip condition before testing can be resumed. The unit features automatic mains voltage selection and an external 24Vdc interlock circuit for connection of emergency off switches aned enclosure interlocks.
