Power Quality Event Investigation & Root Cause Analysis

Incidents like this can have impacts upon your facility’s production and impact the bottom line. Being prepared with the addition of Power Quality Meters and an Electrical Power Monitoring System (EPMS) will allow your facility to see the unseen.

In addition, view the real-time quality of service your facility is receiving from the utility. For example, Event Logs include information on power Sag/Swell, Duration, Magnitude, and Transient Harmonic Distortion (THD). No other energy intelligence solution shows the whole picture of your facility’s energy.

Above all, APT provides solutions. We identify failures like this as they happen and notify the people who need to know faster and with better information – reducing or avoiding impact.

A Power Quality Event (PQ Event) can occur when for many reasons

Is your facility capable of knowing when this type of event has occurred?

Did this event impact your facility?

The ability to see the effects and reactions your facility has during a Power Quality event will give your team control of the unseen.

APT provides solutions to identify failures like this as they happen and notify the people who need to know faster and with better information – reducing or avoiding impact.
