Neo Tele-Tronix Pvt. Ltd. better known by brand name NTPL serves in the field of Electrical and Testing Equipments for over 35 years located in Kolkata, West Bengal.

NTPL manufactures over 60 different types of test and measuring instruments.

“NTPL” make High voltage testing sets are suitable for testing electrical insulation of condensers, transformers, motors, insulators, cables etc. The sets are capable of giving continuously variable DC HIGH VOLTAGE from zero to maximum rated output voltage.

TECHNICAL SPECIFICATION:

Input: Generally, 230 Volts, 50Hz, single phase AC.

However, we also manufacture DC 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 1 KV to several kV(300kV /500kV) with current capacity upto 100mA or higher as required by customer.

Sets of higher current capacity can also be manufactured.

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: Output DC High Voltage is measured by means of properly designed Potential Divider and digital readout unit with proper scaling factor. The HV arm of potential divider is an integrated part of DC   high voltage assembly.

Digital milliammeter along with ‘PRESS TO READ mA’ push button for measurement of leakage          current.   

Protection: Overload & short circuit provided. Zero start interlocking along with Overvoltage alarm & indication are provided.

Mode of operation: Generally, sets are manually operated. Motorisation is also available if required by customer.

Units: 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.

Discharge rod: 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.

             Designed & Manufactured according to relevant IS and International Standards.

Note: Specification & design can be altered according to special requirement of the customer.
