Power Quality Analyzers

Power quality problems cover a wide range of disturbances and conditions. They include everything from very fast transient over voltages that have microsecond time frames, to long duration outages which last hours or days. Power quality problems also include steady state phenomena such as harmonic distortion, and intermittent phenomena, such as voltage flicker. The wide variety of conditions which make up "power quality" also make the development of standard measurement procedures and equipment very difficult.

Most of today's power quality problems originate on the user's side of the meter. Power -quality analyzers are good for locating these. They monitor and record a broad range of power parameters. Voltage and current waveforms, harmonic distortion, and power factor information, as well as other data can be saved and up loaded for detailed analysis by PC software.
