* Qualifications may warrant greater starting base pay within the full pay range. Individual base pay is determined by experience, job‑related skills, and relevant education or training.

This position is responsible for 24/7 system operations including the calibration, commissioning, inspection, maintenance and repair of transmission and distribution equipment and protective relays, switches, apparatus and Power Line Carrier (PLC) communication systems associated with the transmission grid, distribution infrastructure and capital improvement projects.

• Perform maintenance and inspection on substation equipment by following a time‑based maintenance program according to the Cooperative's Substation Equipment Maintenance Standards Plan, manufacturer recommendations and NERC compliance.
• Perform monthly inspection of substation facilities and equipment; maintain records in PEC's maintenance tracking software.
• Execute formal switching orders inside substations as issued by the PEC Transmission Control Center (TCC) to manipulate power flow on the high‑voltage transmission grid or to isolate transmission equipment.
• Write and execute formal switching orders inside substations to manipulate power flow on the medium‑voltage distribution grid or to isolate distribution equipment.
• Install mobile substations for substation construction projects; routine maintenance of substation power transformers or emergency power restoration; perform technical testing of substation equipment using specific test sets including TTR, contact resistance, oil dielectric tests, transformer power factor (Doble) testing, winding resistance, sweep frequency response analysis (SFRA), digital protective relay verification, electromechanical relay calibration, hi‑pot, and phasing.
• Test and inspect substation battery banks and chargers by testing strap impedance, cell voltage, cell impedance, specific gravity, temperature, charging current, and bank voltage.
• Locate and repair DC grounds within substation control systems.
• Perform speed tests, mechanical, and electrical inspection on substation 138KV SF6 gas circuit switchers.
• Perform operating mechanism inspection, motion analysis, contact resistance, gas purity tests, and repair of 138KV SF6 gas breakers.
• Perform operating mechanism inspection, internal inspection, motion analysis, power factor, contact resistance, and repair of 69/138KV oil breakers.
• Extract oil samples from energized substation equipment for dissolved gas analysis (DGA) and fluid quality testing; review and interpret lab results.
• Perform internal inspection and repair according to manufacturer specifications on a variety of substation power transformer load tap changers (LTCs), models including RMV II, UVT, UVW, UZD, UZDRT, UZERT, UTT‑B, TLS, TC525, LRT
  200, and 550H.
• Perform Infrared thermography inspections of substations.
• Repair hot spots on substation switches and connections identified through infrared thermography inspections.
• Perform Partial Discharge surveys on various energized substation equipment.
• Provide expert technical support for substation capital improvement projects (CIP) by installing temporary equipment, performing load transfers, complex high‑voltage switching, and isolation of high‑voltage equipment.
• Commission new substations or newly upgraded substations; energize new substation equipment and perform all tests and electrical checks to ensure reliable operation.
• Verify wiring diagrams and electrical control schematics during substation commissioning projects, making corrections and design changes to ensure proper operation of all equipment and control circuits.
• Program Schweitzer electronic protective relays and function‑test protection schemes by trip checking all new substation equipment.
• Write logic scripts used as test plans for SEL digital protective relay tests.
• Program, test, and commission programmable logic controllers (PLCs) for protection circuits in…
