      voltage Laboratory


At present more than Eight hundred colleges provide engineering education in India . Approximately three hundred of them offer undergraduate programs in Electrical and Electronic Engineering that include High Voltage Engineering. It is mandatory as per the guidelines of the All India Council for Technical Education (AICTE) that the laboratory facilities are to be provided for the programs which are offered by the colleges. However, very few colleges have high voltage and High Power Laboratory facilities due to the involvement of huge costs and availability of specialised faculty members as well as skilled staffs in the field of High voltage and High Power Engineering.

The High Voltage Laboratory is a graduate research and undergraduate teaching laboratory with the following infrastructure and testing facilities:

  • Impulse voltage generator – 800 kV, 40 kJ

  • 500 mm sphere gap for HV measurement

  • Impulse voltage divider (damped capacitive type) –800 kV

  • Digital impulse oscilloscope with software

  • 300 kV AC power frequency  HV testing transformer

  • AC Divider 300KV                           

  • Partial Discharge Measuring System

  • Coupling Capacitor

  • Vessel for Vacuum and Pressure

  • Measuring Sphere gap - 500mm

  • RIV Measuring Instrument

  • Operation with Information Communication Technology (ICT) of Impulse as well as AC test system, an unique facility in India .

  • Capacitance and tan delta measurement

  • Resistivity meter

  • Leakage current tester



  • HV Impulse testing 
  • HV Dry / Wet Power frequency testing
  • Capacitance and Tan delta measurement 
  • Partial discharge measurement 
  • Insulation Resistance 
  • RIV, Corona measurement 
  • HV Calibration, CT/PT Calibration
It specialises in the measurement and testing of equipment and components of Electric Power Engineering. Teaching in laboratories includes studying the breakdown of air under varying atmospheric conditions, especially moisture, varying supply voltage and under multiple insulation arrangements.  They are particularly geared towards the use of live-line techniques for transmission and distribution system maintenance. Transformer insulation condition measurement is also a set laboratory exercise. Lectures in High Voltage are embodied into specific courses associated with Electric Power Engineering. NIT, Durgapur is having the above facilities towards the High Voltage testing, it will also meet the innovative course work, curriculum, research of the students and the testing needs of nearby utilities and industries providing the application of ICT, remote operation facilities.
