Growth and Contribution of The High Voltage Division

The High Voltage Laboratory at Bangalore was initiated around 1964 in the campus of Indian Institute of Science, also called as Tata Institute. the period between 1978 and 1983 in the history of the High Voltage Laboratory of CPRI could be termed as very productive in building up the expertise in R&D, testing and consultancy that paved way for formulating a road map for ensuring a bright future for the high voltage engineering in CPRI. The activities of the division can we attributed to EHV Test Laboratory (Main Laboratory), Mobile Field Testing Laboratory, Pollution laboratory, Impulse Current Laboratory, Development of measuring equipment like Electro-static fi eld measurement instruments, High Voltage Test and Measurement Instruments and other developments include Grading Ring for EHV/UHV Insulators and Surge Arresters, and Minimum clearance requirement for transmission towers of 765 kV System.
