We are an eminent name in the industry, engaged in manufacturing, exporting and supplying high quality DC High Voltage Test Set. This test set is suitable for testing electrical insulation of condensers, transformers, motors, insulators, cables, etc. It is capable of giving continuously variable DC HIGH VOLTAGE from zero to maximum rated output voltage. This test set is manufactured at our well-equipped manufacturing unit under the observation of our experts using premium quality components. Offered DC High Voltage Test Set can be purchased from us at pocket-friendly prices.
Generally, 230 Volts, 50Hz, single phase AC. However, we also manufacture DC H.V. sets workable on other input voltage at extra cost.
Continuously variable from zero to maximum rated output voltage.
Spread over a wide range of sets from 1 KV to 300KV with current capacity upto 100mA. Sets of higher current capacity can also be manufactured.
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.
Output DC high voltage measured by HV resistor chain along with micro-ammeter scaled in kV. Milli-ammeter to measure the leakage current. Digital meters may be provided at extra cost.
Overload & short circuit provided. Zero start interlocking along with Over voltage alarm & indication are provided.
Mode of Operation:
Generally, sets are manually operated. Motorization facility can be available at extra cost.
Generally DC high voltage test sets are available in one unit upto 35KV and sets of higher output voltage are commonly manufactured in two units i.e. the control unit & Transformer" Rectifier unit. This Transformer" Rectifier unit are made cascaded type above 80KV. However, NTPL always welcome customers' choice regarding the no. of units.
A discharge rod is provided with the set. DC high voltage is generally obtained by simple rectification of AC high voltage or by multiplication of relatively low AC high voltage by proper multiplier circuits as is found suitable for a particular DC HV test set. HV transformers of the Test Sets are Cast Resin types.
