Research Assistant (High Voltage Testing) 01/2017 - 09/2019
Mississippi State University, Starkville, MS United States
Industry: Electrical Equipment Testing
Worked as a testing engineer at Mississipi State University High Voltage Laboratory
• High Voltage testing of electrical equipment in accordance with ANSI/NEMA, IEEE and IEC standards. Testing includes lightning/switching impulse, AC and DC wet/dry low frequency tests • Long term degradation testing/diagnostics for MV distribution network insulators, cutouts, switches etc. This includes tracking & erosion, thermal cycle, temperature rise, salt and fog tracking and long term partial discharge tests • Automation of all electrical equipment’s based on Programmable Logic Controllers using RS Logix 500 and National Instruments data acquisition modules using LabView • Preparation of standard test reports for commercial customers testing based on IEEE, IEC, and BS standard and recommended practices. • Development of a standalone application for impulse voltage testing in MATLAB and C language interface. Application automates the process of determining the 50% disruptive discharge impulse voltage based on up & down method, computes and validates the linearly rising front test, and calculates the 3/0 and 15/2 impulse voltage withstand tests • Design of control for three-phase grid-connected inverter based on phase locked loop (PLL) controller in MATLAB - Simulink environment. Simulations were further analyzed, processed, and corrected in a custom-built program by using Python language • Development of numerical/analytical electro-thermal model for distribution transformers in COMSOL Multiphysics • Development of autonomous condition monitoring systems based on probabilistic modelling of lifetime partial discharge data (PhD Dissertation) - Real time application designed in a MATLAB software for automating the PD data storage, PD forecasting, and PD detection threshold over a wide area power system network.--
