Nuclear · Client: Nuclear Power Plant
Retuned three legacy GE 9T66Y988 power supply modules from 50 Hz to 60 Hz operations, refreshed capacitors, repaired a damaged coil, and completed a 100-hour nuclear-grade burn-in.
Industrial
Restored an ASCO automatic transfer switch damaged by an electrical fire. Replaced the back-plane, main switch assembly, control PCB, solenoid, and wiring harnesses, refreshed capacitors, and performed a 100-hour loaded burn-in.
Industrial
Refurbished a legacy ABB KD-11 distance relay with mechanical damage by sourcing like-for-like surplus parts, replacing the shattered cover and rear terminal-block guard, and performing final functional testing.
Nuclear · Client: Steam Electric Station
Restored full functionality to a thermally damaged Rochester isolator card using reverse engineering, Commercial Grade Dedication, and custom board manufacturing without original OEM documentation.
