Research Lab:
The main focus of research is on nanodielectrics for power applications. In addition, ageing, life estimation, power equipment modelling design and development research is being carried out.
Latest research on spacecharges in modern ultra resistive dielectrics, external current measurement upto fempto ampere level, DC & AC breakdown tests, measurement of capacitance, loss tangent and characterization of dielectric materials is being promoted in this laboratory.
Four Ph.D. students already defended his thesis. Currently, ten research students are working for their thesis in this lab and are at different stages of their research program.
Please visit the link given below for details:

UG (HV) Lab:
High voltage lab is developed quickly by Dr. Reddy for supporting lab component of high voltage engineering (EEL 314, EEL 705) for undergraduate students. Later to the post graduate students of Power Engineering. It is a compulsary lab for PG course, making the PG course rich in practical exposure. A high voltage lab to power engineering is like a hospital to a medical college, which provides a glimpse and exposure of HV equipment such as transformers, machines, capacitors, bushings, power cables etc. It is aimed at training students opting for core power companies like ABB, Schneider etc.
It was started at Room No:136 in transit campus in 2012. Each year about 60 students registered the course making the lab to run three times a week for lab work - was one of the busiest labs of the department. Among the new generation IITs this is believed to be the first high voltage lab in the area of Electrical Engineering. The lab is also supporting/being supported by sponsored projects.
The equipment is partly sponsored by the institute and the rest purchased from Dr. Reddy's projects.
