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. Protection: Tripping mechanism for protecting the H.V. transformer against over loading. The tripping mechanism can be adjusted at 25,50 & 100% of the rated current by a rotary switch. Below 100mA & above 20mA two adjustable tripping ranges are at 50% &100%, while for sets of 20mA capacity or below only 100% is adjustable [If required by the users tripping current can be made adjustable at other values, at extra cost]. Apart from tripping mechanism, Zero start interlocking along with Overvoltage alarm & indication are provided. Mode of operation: Sets are generally, motor operated beyond 20KVA & 50KV.
