T&R VC24-24 Vacuum Bottle AC Test Set

The T&R VC24-24 is a general purpose high-voltage AC test set, ideal for Flash Testing of plant and  switchgear, such as circuit breaker vacuum bottles, with voltages up to 24kV AC. The output voltage is variable from 0 to 24kV. A zero voltage interlock is provided, ensuring that the output may only be energised with the voltage control at zero.

The unit features automatic mains voltage selection and an emergency off switch. The output voltage and current are metered by large, linear analogue instruments. The unit has a x0.1 range on the mA meter. The mA meter is marked with a green scale for currents under 1-mA and a red scale for current larger than 10mA.

The test object and output are protected by an adjustable electronic current trip. The trip level may be set to 16, 20 or 24mA. Breakdown of the test object is visibly indicated and the unit must be manually reset after a trip condition before testing can be resumed.

The output of the VC24-24 is supplied via a permanently connected and partially screened high voltage cable, 2 metres long and terminated in a large clip. This stows in the lid for easy transit, along with the ES30 earthing stick and earth lead.
