Power and harmonic analyzers

Power and harmonic analysers are specialised devices for the continuous measurement of network parameters and power quality.

These devices measure voltage and current parameters such as voltages, peak voltages, frequency, active power, reactive power, apparent power, power factor and power shift factor, active and reactive power demand, voltage harmonics, current harmonics, phase angle of the fundamental component, total harmonic distortion or voltage asymmetry factor.

The devices are equipped with measuring clamps and software as standard, some models have built-in calendars and a clock, as well as a real-time recording system.

They meet the requirements of EN standards, including

• provide control of power quality parameters,
• allow the causes of faults or failures to be determined,
• locate devices that introduce interference into the network,
• enable the recording of events such as voltage collapses, surges, flickering lights and short-term power cuts.
