HISTORY
The Division of High Voltage Engineering in School of Electrical and Electronics Engineering was created in the year 1960 and the Post Graduate course was offered in High Voltage Engineering in 1964. On roll about 25 postgraduate students and 11 Ph.D scholars are in the Division of High Voltage Engineering. The Postgraduate course in High Voltage engineering has been awarded “ A ” grade by National Board of Accreditation.

The major areas of research in high voltage engineering are Design of high voltage power apparatus,Estimation of Electrical field strength in power apparatus, Development of methods of detecting faults during impulse voltage testing, estimation of over voltage power apparatus, study of Micro-arrays and development of Gene chips .

The major equipment available in the laboratory are 1540 kV Impulse Voltage Generator, 12kv Impulse Generator, 450 kV Cascaded Transformer, Partial Discharge Detector, 420 kV HVDC generator,Mavowatt 45 Energy Analyzer Kit, Earth Resistance Tester, Insulation Resistance Tester, High Voltage Schering Bridge and digital measuring devices like 12 bit VXI based data acquisition system and digital storage oscilloscope are used extensively.

The High Voltage Laboratory has testing facilities which is recognized by National Test House. Consultancies are regularly taken up by which have relevance to post graduate teaching. Many industries from all over India get their high voltage power apparatus certified as per Indian Standards and other International Standards.

The Division of High Voltage Engineering has been recognized by COSIST and DSA programme, AICTE has sanctioned three projects,’ Modernization of High Voltage Engineering ‘ under MODROB
( Rs. 12.00 Lakhs ), ‘Centre for Design and Quality Assurance of High Voltage Power Apparatus‘ under TAPTEC ( Rs. 13.00 Lakhs), Characterisation of Insulation Strength of Transformer for Non-Standard Impulse Voltages’ under R&D project(Rs. 12.00 Lakhs) in the last five years.
