• Tested and commissioned protection relays, meters, circuit breakers, CTs, and VTs across multiple medium
voltage substation projects, ensuring 100% compliance with IEC standards.
• Executed primary and secondary injection testing for current transformers (CTs) and voltage transformers (VTs)
using the Omicron CPC 100 multi-functional testing system.
• Performed high voltage (HV) testing on medium-voltage cables and switchgear using the Megger MIT515 5kV
Insulation Tester to ensure insulation resistance and withstand levels.
• Conducted comprehensive transformer testing, including turns ratio and winding resistance measurements,
utilizing Megger TTR320 and MTO330 equipment.
• Performed circuit breaker timing and travel analysis using the TM1600 Breaker Analyzer System to verify
mechanical operation and synchronization.
• Analyzed solar PV system performance on plants exceeding 40 MW, utilizing the Solmetric PV Analyzer PVA-1500
for string-level I-V curve tracing and irradiance-corrected output measurements.
• Conducted scheme and functional checks to validate control logic, interlock schemes, and protection
coordination prior to system handover.
