Analyze and interpret relay event records and fault waveforms to diagnose system issues.
Work with electromechanical, microprocessor-based, and digital relays from manufacturers like SEL, GE, ABB, and Siemens.
Test and verify differential, overcurrent, distance, and voltage protection relays to ensure proper operation.
Inspect and maintain relay panels, control circuits, and protection schemes for breakers, transformers, and generators.
Identify and correct relay mis-operations, incorrect settings, and wiring issues.
Assist in investigating system outages and disturbances to improve reliability.
Collaborate with engineers and field teams to implement relay protection upgrades and system improvements.
Maintain accurate test reports, maintenance records, and relay settings for compliance with NERC, IEEE, and utility standards.
Follow industry safety protocols and ensure adherence to NETA testing standards.
Communicate effectively with team members, clients, and project managers.
