Power quality analyzers are the generally used tools to capture readings and collect data for analysis. While some are permanently installed in the distribution system, handheld analyzers are utilized for numerous applications, especially troubleshooting.
Handheld analyzers are lightweight and capable of measuring a variety of parameters. The most typical include voltage, amperage, frequency, dips (sags) and swells in voltage values, power factor, harmonic currents, and the resulting distortion and crest factor, power and energy, voltage and current unbalance, inrush current values, and light flicker.
