About Power Monitors, Inc.
Built in Virginia. Trusted by the industry since 1987.
Power Monitors, Inc. (PMI) is an industry-leading power quality instrument design and manufacturing firm headquartered in Mt. Crawford, Virginia. For nearly four decades, we have solved power quality problems for electric utilities and electricity end-users by listening to our customers and engineering the instruments they need to get the job done right.
Who We Are
Power Monitors, Inc. is an industry-leading power quality instrument design and manufacturing firm headquartered in the Shenandoah Valley of Virginia. From our beginnings in 1987, we set out with a single goal: solve real power quality problems by listening to our customers and working with them to design and manufacture the products they actually need to do their jobs.
That customer-first mindset still defines us today. Every power quality recorder, voltage monitor, and analyzer we build is shaped by real conversations with the utility engineers, industrial technicians, and end-users who put our instruments to work in the field, in substations, and inside the meter socket. When our customers tell us what they need, we build it. When they run into problems, we help them solve them.
Total customer satisfaction is our goal — backed by 24/7 technical support from real PMI engineers, and an extensive library of technical white papers and educational videos so no matter how tough your power quality problem, you are never working on it alone.
Our History
Nearly four decades of power quality innovation.
Power Monitors, Inc. has spent more than 38 years quietly building a reputation as one of the most trusted names in power quality instrumentation. What started as a small Virginia engineering firm with a single mission has grown into a company whose products help utilities across the United States keep the grid running clean and reliable — but the core philosophy behind everything we do has never changed.
1987 — A Virginia engineering firm with one mission
Power Monitors, Inc. was founded in 1987 in Mt. Crawford, Virginia, with a mission that has not changed in almost four decades: solve real-world power quality problems by listening to customers and designing the instruments they actually need. Rather than build generic monitoring equipment and hope it fits, our founders spent time with utility engineers, understanding the specific challenges they faced in the field. That commitment to listening became the foundation of every product we have designed since.
Growing into an industry leader
What began as a small Virginia engineering firm has grown into an industry-leading manufacturer trusted by electric utilities, industrial facilities, and electricity end-users across the country. Over the years, PMI engineers have earned patents in power line communications, power quality instrumentation, and energy monitoring — and contributed actively to IEEE standards groups that shape how the industry measures, monitors, and reports power quality. Our engineers have published dozens of white papers on harmonics, voltage sags, flicker, DER interconnection, and other power quality topics that are now widely referenced across the industry.
Where we are today
Today, PMI offers a full line of power quality instruments — from the meter-base Bolt recorder to the wireless Seeker to the high-speed Revolution — all supported by our PQ Canvass cloud platform and Merlin AI-powered analytics. Every instrument is backed by ongoing research and development, comprehensive training programs for utility engineers, and around-the-clock customer service. The Virginia roots and customer-first philosophy that started it all are still right here at the center of everything we do — and always will be.
What We Do
Engineered for the people who keep the grid running.
PMI designs and manufactures power quality instruments for electric utilities, industrial facilities, commercial buildings, and electricity end-users across the United States. Our three flagship recorders — Bolt, Seeker, and Revolution — cover every deployment scenario, from tight meter-base enclosures to substation transient investigations. Behind every product is a team of engineers who understand power quality because they have spent decades solving these problems in the field.
Product Design & Engineering
In-house engineering of power quality recorders, voltage monitors, current sensors, and analyzers — every product designed by PMI engineers to solve the real problems utility teams face in the field, substation, and service entrance.
U.S. Manufacturing
Every PMI instrument is designed and built in Mt. Crawford, Virginia — giving us tight control over component quality, production lead times, and the ability to iterate quickly with customers when a new use case comes up in the field.
Training & Education
PDH-eligible classes, on-site training programs, live webinars, and a library of technical white papers help customers get real value out of every measurement they take.
