Testing & Diagnostic Services

RESA Power is a reliable and safe power systems testing company for all required testing. We make sure your new or revamped electrical system will operate as it was designed, so you can minimize start-up delays and costly electrical deficiency issues. Trust the professionals at RESA Power to provide a comprehensive high voltage testing plan for maximum productivity for your equipment.

Electrical Acceptance Testing & Commissioning

New equipment requires electrical acceptance testing and a thorough examination after being installed and wired into your environment. Insurance companies may require electrical acceptance testing before your new electrical equipment is energized to verify that it meets code requirements and satisfies the intent of the application.

According to electrical equipment manufacturers, up to 30% of new electrical equipment fails to operate properly due to mishandling, improper installation, construction debris, and dust. Acceptance testing will protect the validity of your manufacturer’s warranty through non-biased, independent testing and will set a benchmark by which future equipment testing can be compared.

The start-up of any electrical system is a unique occurrence and could expose some outstanding problems. Commissioning by qualified RESA Power professionals can verify proper operation and identify installation problems to assure total system performance.

RESA Power Service offers power system commissioning and acceptance testing. We make sure your new or revamped electrical system will operate as it was designed to so you can minimize start-up delays and costly electrical deficiency issues.

Services include:

Acceptance Testing

Confirm your newly installed electrical equipment, switches and connections meet all design and function standards with our electrical systems testing. RESA Power Service will follow NETA’s standards to validate that new or retrofitted electrical equipment is performing to the manufacturer’s specifications. Electrical systems testing of equipment before energization will prevent damage to other components and ensure the safety of your personnel. This power system testing allows for a baseline report and error-free operations before start up.

Our technicians are fully certified to perform acceptance testing on:


Reduce cost and improve energy-saving capabilities during new construction projects with our commissioning services. We’ll help you confirm that your equipment, machinery, and systems have been properly installed, tested, validated, and are ready for safe operation within your overall power system.

Highly-skilled, certified technicians and engineers follow the procedures and practices set out in NETA’s commissioning standard. Proper electrical system testing can prevent costly start-up delays by detecting potential problems before they become critical.

RESA Power can also act as the owner’s representative or commissioning agent on your behalf, coordinating our power system testing services with those provided by the electrical contractor. Make sure your equipment is running at the best of its ability with RESA Power.

Electrical Maintenance Testing

Ground testing is required by the National Electrical Code (NEC) and most insurance companies. Your insurance company may require high current testing, as well.

RESA Power will keep your electrical system in optimal operating condition by performing all necessary switchgear inspections, tests, cleaning, and calibration. Our electrical maintenance and testing programs follow electrical testing standards developed by the International Electrical Testing Association (NETA) which is recognized by the American National Standards Institute (ANSI) as an accredited standards developer.

Services include:

Electrical Asset Management Program

This electrical preventive maintenance program is comprised of both de-energized and energized preventive maintenance task items:

  • Designed based upon manufacturing requirements, codes, NETA, NFPA 70E & 70B recommendations and OSHA requirements
  • Web-based – all field data uploaded to a database allowing the client to track and trend equipment that has been tested
  • Energized testing includes infrared scanning, visual inspections, voltage, and current diagnostics, partial discharge and ultrasonic testing

Electrical Preventive Maintenance

Energized testing includes:

  • Infrared scanning.
  • Visual inspections.
  • Voltage and current diagnostics and ultrasonic testing.
  • Limited cleaning and repairs within the safety guidelines.

De-Energized testing includes:

  • Primary and secondary injection testing of breakers
  • Relay and meter testing
  • Turns ratio testing and oil analysis for transformers
  • Resistance testing for cables and busways
  • Cleaning and torquing of all electrical components

Partial Discharge Cable Testing and Monitoring

Protect your equipment from insulation defects before it evolves into an electrical outage. This electrical system testing checks medium and high voltage cables for erosion and decline. Our experienced staff will look for signs of a tree-shaped pattern, which indicates a cable breakdown is imminent.
