Responsibilities & Context:

1. Transformer Design Development: Lead the electrical and mechanical design of power/distribution transformers for both single phase and three phase (ratings, vector groups, insulation, cooling systems, coiling, core etc.) following IEC, IEEE, ASTM etc. standard.

2. Standards Compliance: Ensure all designs and tests comply with international standards like IEC, IEEE, and customer specifications.

3. Type & Routine Testing Oversight: Supervise all testing activities including routine, type, and special tests (e.g., IR, ratio, impedance, induced voltage, lightning impulse).

4. Design Optimization & Cost Control: Optimize transformer design for cost, efficiency, losses, and material utilization (core, copper, insulation).

5. Failure Analysis & Troubleshooting: Investigate test failures or field issues and implement corrective design or process improvements.

6. Technical Documentation: Prepare and review drawings, design calculations, datasheets, test reports, and manuals

7. Test Equipment & Lab Management: Ensure proper calibration and maintenance of testing equipment (Ratio Tester, Resistance, Insulation, HV test sets, DVDF, Impulse etc.).

8. Quality Assurance Implementation: Establish and maintain QA/QC procedures for transformer testing and design validation.

9. R&D for new transformer technologies (low-loss core, eco-friendly insulation)

10. Digital tools (AutoCAD, FEM analysis, simulation software)

Design Knowledge:

Thermal & Dielectric Design Analysis

Perform detailed thermal modeling and insulation coordination to ensure safe temperature rise and dielectric strength. 

1. Short-Circuit Withstand Design: Ensure transformers meet short-circuit strength requirements as per IEC / IEEE standards.

2. Loss Capitalization & Efficiency Improvement: Evaluate no-load and load losses with capitalization cost analysis to meet utility tender requirements.

3. Material Selection & Specification: Approve core materials (CRGO), conductor type, insulation systems, and oil specifications.

4. Insulation System Design: Develop insulation structures (solid, liquid, pressboard) for high-voltage reliability and long life.

5. Design Validation through Simulation: Use FEM / simulation tools for electromagnetic field, leakage flux, and mechanical stress analysis.

6. Prototype Development & Testing: Lead development of new designs and validate through prototype testing and performance evaluation.

7. Tap Changer Design Integration: Coordinate design and selection of OLTC/Off-circuit tap changers and their control schemes.

8. Advanced Diagnostic Testing: Oversee tests like SFRA, DGA interpretation, partial discharge, and tan delta for condition assessment.

9. Test Procedure Development: Develop and standardize detailed testing procedures and checklists for factory acceptance tests (FAT).

10. Third-Party Inspection Handling: Coordinate with inspection agencies like BUET/DUET or customer representatives from BREB/PDB/DESCO/DPDC/NESCO etc.
