Electrical Tester

Build Your Career with Summit Service Solutions – Where Skilled Professionals and Opportunity Meet.

We are seeking an experienced Electrical Tester to lead the diagnostic testing, megging, and documentation phases for secondary substations at our mission-critical data center facilities. In this role, you will be the final line of quality assurance before primary systems are energized. You will execute comprehensive electrical testing on medium- and low-voltage infrastructure, rigorously document all findings to satisfy commissioning standards, and ensure the facility's power distribution meets strict reliability requirements for 100% uptime operations.

• Perform comprehensive insulation resistance testing (Megger testing) on medium-voltage and low-voltage cables, switch gear, transformers, and busways to verify insulation integrity.
• Execute secondary substation testing, including primary and secondary injection testing on circuit breakers, contact resistance testing (Dductor), and Hi-Pot/VLF testing.
• Verify the proper operation of protective relays, current transformers (CTs), potential transformers (PTs), and interlock schemes.
• Conduct power quality analysis, phase rotation checks, and load bank testing to validate the performance of the secondary distribution system under stress.
• Safely operate and calibrate advanced electrical testing equipment (e.g., Megger, Fluke, Omicron, Doble).

• Generate meticulous, audit-ready test reports for every component within the secondary substation, ensuring data aligns with OEM specifications and site design parameters.
• Maintain accurate real‑time digital logs of all megging results, baseline metrics, and environmental conditions at the time of testing.
• Identify, document, and track electrical deficiencies or anomalies in a centralized punch‑list system, collaborating with contractors to resolve issues prior to final turnover.
• Update redline drawings and assist in the finalization of electrical as‑built documentation for the facility management team.
• Prepare final handover packages and Method of Procedure (MOP) documentation for the data center operations team.

• Strictly adhere to OSHA regulations and site‑specific Lockout/Tagout (LOTO) procedures during all testing phases.
• Collaborate closely with the Commissioning Agent (CxA), General Contractor, Electrical Engineers, and Data Center Operations staff to schedule testing windows without impacting active loads.

• Experience: Minimum of 3 years of hands‑on experience in electrical testing, commissioning, or maintenance of medium/low‑voltage substations. Previous experience in data centers, hospitals, or similar mission‑critical environments is highly preferred.
• Technical Knowledge: Deep understanding of electrical theory, relay logic, transformer configurations, and power distribution systems up to 35kV.
• Equipment Mastery: Demonstrated proficiency with advanced testing apparatus, particularly insulation resistance testers (Megger), micro‑ohmmeters, and relay test sets.
• Communication: Exceptional written communication skills required for highly detailed technical reporting and documentation.

• Ability to lift and transport testing equipment weighing up to 50 lbs.
• Comfortable working in an active construction and data center environment, which includes varying temperatures, loud noises, and navigating tight spaces (e.g., beneath raised floors or within switch gear rooms).
• Flexibility to work off‑hours, weekends, or night shifts during critical commissioning
• If an offer is extended, you will be required to consent to a drug screen and background check. We are a drug‑free company.
