Power quality is simply determined by the way power that is produced interacts with the appliance connected to it. If power supplied fits inside of the parameters that the device can safely function then the power quality is sufficient. If there are voltages and variations outside of that range then possible damage or malfunctioning can occur.

Anything from the amplitude of the voltage to harmonics and unexpected distortions can play a role in power quality. The only way to combat these problems is either make the power “cleaner” or make the devices “tougher”. When dealing with sensitive pieces of equipment it is important to know the power quality being produced.

This meter measures a multitude of parameters including AC voltage and current, active power, apparent power, reactive power, power factor, frequency, phase, harmonics, crest factor and energies. All of these variables tested together give a complete picture of the power quality. This meter has the added ability to record (data log) information on these parameters and then download it to a PC for further analysis and graphing.

This kit includes 1200A 12” flexible current clamp probe for wrapping around bus bars and oddly shaped conductors. This is a complete system for power quality testing and is trusted by professionals. The PQ3350-1 Power Quality Analyzer User Manual is attached to this page to answer any further questions.
