Automatic Ac High Voltage Test Sets

NTPL" make Automatic AC High Voltage Test Sets are suitable for Power frequency AC high voltage test on transformers, motors, insulators, cables etc. The sets are capable of giving continuously variable AC HIGH VOLTAGE from zero to maximum rated output voltage.

Input : Generally, 230 Volts, 50Hz, single phase AC, upto 10KVA & 400/415V, two phase out of three phases for sets beyond 10KVA.
However, we also manufacture AC H.V. sets workable on other input voltage at extra cost.

Output : Continuously variable from zero to maximum rated output voltage

Capacity : Spread over a wide range of sets from 2.5KV to 300KV AC having capacities from several VA to hundreds of KVA.

Duty cycle : Intermittent i.e., 5 minutes ON, 10 minutes OFF. However, test sets of continuous or other duty cycles can also be manufactured at extra cost.

Metering : Analog voltmeter & milliammeter/ammeter. Digital meters may be provided at extra cost.
