Home/Power Quality Analysers/Class A Power Quality Analysers

Class A Power Quality Analysers offer the highest level of accuracy and are typically used in applications where data is needed to help resolve disputes with the supplier or were compliance with standards needs to be proved.

Class A defines the measurement time accuracys (better than +/- 0.3 sec/day) for parameters such as voltage, current and harmonics. With defined methods and measurement uncertainties for Power Supply Voltage, Voltage Fluctuations (Flicker), Voltage Unbalance, Voltage and Current Harmonic.
