The VC24-24 Mk3 AC Test Set 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.
2 overload protection circuits are provided on the units. The first is the user selectable output level trip, which allows current of 16mA, 20mA or 24mA to be set. A trip condition is indicated by an illuminated push button and an audible alarm. The second trip circuit is a magnetic circuit breaker operating on the primary of the HV transformer. This operates on large overloads, such as under flashovers.
VC24-24 Mk3 AC Test Set is conveniently housed in a compact and portable aluminium case, weighting 27kg. It comes with a permanently connected 2-meter long HV output lead, ensuring flexibility and ease of use during testing operations.
Our partners, such as Acutest, Alpha Electronics, Cuthbertson Laird, Norwich Instrument Services, and PASS Ltd offer the VC24-24 Mk3 in the United Kingdom. Instrument is also available through our worldwide distribution network.
