As a supplier of power conditioning equipment for critical real-time applications, Power Systems & Controls (PS&C) has learned the importance of change. Whether changes are due to additional load or new technology, our customers can rest assured that their equipment is capable of handling their needs. Due to problems that can arise when newer technology is coupled with the old, PS&C consistently strives to develop compatible service enhancements so that our customers’ critical loads are never compromised.

In the past, it has been common practice to document the performance of a UPS system at start-up. However due to the various power quality problems we’ve encountered over the years, PS&C is pleased to announce that we now offer a power quality monitoring service. In our continuous effort to maintain state-of-the-art test disturbance equipment, we have added monitoring equipment which collects and qualifies electrical data on almost every aspect of three phase power system. This includes voltage, current, frequency, impedance, power factor, demand and all other types of electrical disturbances.

PS&C offers this service to our customers of any others interested in avoiding or resolving power quality problems. PS&C will work with your facilities’ personnel or electrical engineer to collect accurate data independent of your equipment manufacturer. If the power quality study has not been done prior to equipment purchase, we recommend that it be conducted at start-up. For a small fee PS&C will provide a comprehensive power study which will serve as a baseline for your facility. The study should be updated each time major changes in equipment are made or every two years to document your current power system performance.

Another power quality issue of concern to the power conditioning industry is Total Harmonic Distortion or THD. The IEEE 519.1992 recommended standard outlines the amount of harmonic current that can be reflected to a power source. In addition to the above, the power study now offered by PS&C can also identify harmonic current sources to determine your overall power quality and tell you if your THD problems are self-induced.
