Power Quality



Designing and Delivering Solutions To Power Quality Challenges

At Alpha Engineering, Inc. (AEI), we have a deep understanding of the challenges you face with electrical systems and Power Quality concerns. Issues such as extended outages, momentary surges or under or over voltage conditions can impact production, cause unnecessary delays and prove costly to equipment.

That’s why we offer comprehensive solutions that are results driven and cost-effective. By examining specific parameters such as voltage, current, harmonic content and frequency, AEI performs Power Quality investigations that offer you reliable, practical ways to solve any issues or concerns. These parameters will often be outside of industry-accepted boundaries if an electrical system is functioning poorly. When it comes to Power Quality, we make it our top priority to ensure that your equipment is working properly and that the electrical system’s parameters are within acceptable limits.
In order to investigate an electrical system, a site survey is performed. The four basic components to a site survey are:

Determine soundness of the wiring and grounding system

Establish sources and impact of disturbances on equipment performance

Verify quality of the AC supply

Acquire and analyze survey data to guide system improvements or corrective actions if necessary

We use a variety of industry-standard tools, including:

PMI Revolution

AEMC 8335 PowerPad 3-Phase Power Quality Analyzer

Fluke 43B Single Phase Power Quality Analyzer

AEMC 3711 Clamp-On Ground Resistance Tester

Miscellaneous multimeters, oscilloscopes or temperature probes

Dranetz Power Xplorer PX5

Reliable Power Meter 1656 Power Recorder (re-branded to Fluke 1750 after RPM was purchased by Fluke)

AEMC 1040 Megohmmeter Field Kit

AEMC 4500 Digital Ground Resistance Tester
