Currently, I am in-charge of Applied Superconductivity Laboratory (ASL-Lab), Cold Electronics and Control Laboratory (CEC-Lab), Vacuum Technology Laboratory (VTL-Lab) and Liquid Helium (LHe) Plant and User Facility at Cryogenic Engineering Centre. Following are the particulars of research work:
HTS Superconductor for Power Applications:
-> HTS Cables: The Applied Superconductivity Laboratory is a unique advanced research lab of the country which deals with teaching & hands on training of students and industry personnel for the design, development and testing of High Temperature Superconductor based Power devices as a preparation for setting up India's first superconducting power grid. The lab has in-house developed India’s first 7 m long ,11MVA, 11 kV, 1kA, AC and DC High Temperature Superconducting (HTS) power cable operating at 77 K through the sponsored research project by CPRI, Bengaluru and has cleared TRL- 4 Level.
->HTS magnet: for SMES and MRI lab scale prototype along with 3-Axis automatic magnetic flux density measurement setup is developed.
-> HTS SFCL: I-SFCL development is in-progress.
->HTS Machine: HTS generator prototype is developed in-house and motor work is in-progress with industry.
Cold Electronics and Cryo-instrumentation:
-> Research and development of electronic circuits and sensors operational at low temperatures (from 300 K down to 4.2 K) is an on-going laboratory activity.
-> Cryogenic flow metes & control valve calibration facility using sub-cooled liquid nitrogen is developed.
-> Temperature sensor calibration down to 4.2K is developed .
-> Cryogenic UTM testing machine in-house developed for testing different polymers at 77 K.
Cryogenic Process Control:
Superconducting technology is a three-tier application which requires the supports of cryogenic cooling system and the operation these cooling systems requires support of vacuum technology, therefore several indigenously teaching and research facilities are developed for the skill upliftment of students and industry personnel for designing, developing and operating such cutting-edge technologies in closed using LabVIEW and PLC based SCADA systems.

Area of Research: Optimal Location of Superconducting Fault Current Limiter (SFCL) in Power System: The thesis will deal with the limitation of fault currents using superconducting fault current limiters for different types of faults. These devices are required to be situated optimally in the power system for safe guarding switchgears during fault by limiting the fault current. The selection criteria of SFCL based on fault current level will be investigated.
