Power Quality is a measure of how well a system supports reliable operation of its loads. A power disturbance or event can involve voltage, current, or frequency. Power disturbances can originate in consumer power systems, consumer loads, or the utility. Our range of power meters include both single-phase and three-phase power quality analyzers for predictive maintenance, quality of service compliance testing and load studies. We can meet the new IEC Class A standards for flicker and power quality.
