Power quality diagnosis and resolution

If you experience problems after we verify incoming power quality, you may need electrical professionals:

  • Electrical contractors. You may have an ongoing relationship with a particular electrical contractor for internal wiring or other electrical services. Electrical contractor staff electricians typically can identify and resolve most power quality problems.

  • Independent electrical testing firms. Such firms provide specialized staff and diagnostic equipment to analyze and recommend resolution of power quality and other internal electrical problems. The testing firm typically includes engineers who have expertise to handle difficult power quality problems. Their independence from mitigation equipment manufacturers, vendors and related service providers means they provide unbiased evaluations and recommendations. Their recommendation is implemented by your electrical contractor, consulting engineer or other electrical professional.

  • Consulting engineers. Consulting engineering firms typically are retained on an individual project basis and provide:
    • New installation design or design/build (proactive power quality mitigation)
    • Power quality investigation and resolution recommendations
    • Mitigation equipment installation and implementation project management

Electrical professionals have specific roles in helping ensure your internal electrical environment is compatible with your equipment and systems. Capabilities range widely among firms in each category in diagnosing and resolving power quality concerns.
