High Voltage Laboratory

The inception of the High Voltage Laboratory dates back to 2007 when it was established with financial support through the DST FIST project. Professor Saibal Chatterjee, currently a faculty member at NIT Mizoram, played a pivotal role in its supervision. The laboratory primarily engages in Research & Development initiatives, as well as conducting classes for both undergraduate and postgraduate students. It has facilities for power frequency high voltage generation of 100 kV AC, 145 kV high voltage DC & 300 kV, 7.5 kJ, 1.2/50 microsecond Impulse Voltage, Measuring Sphere Gap MF-100, Electronic Sphere EZK, 2-Channel, 200MHz Digital Storage Oscilloscope with software for direct transfer of data from Oscilloscope to PC. Other facilities, such as an automatic oil AC breakdown tester (Make: BAUR, Model: DTA 100C), Oil tan delta measuring unit (Model: ADTR-2K PLUS), Rotational digital viscometer (Model: Brookfield DVE), Dissolved Gas Analyser (Model 5770), Vacuum oven, Hot air oven, Oil Moisture Meter (Vaisala MMT 62), and prototype 25 KVA distribution transformers, were procured under different research projects headed by Dr. Anu Kumar Das, with financial support from agencies like DST SERB, CDB Kochi, and AICTE New Delhi.
