The multifunctional Class A power quality recorder is used for acquisition, visualization, evaluation and transmission of electrical measured variables such as alternating current, alternating voltage, frequency, power, harmonics etc. The acquisition, processing and accuracy of measured

variables and events are performed according to the IEC 61000-4-30 Class A power quality measurement standard.

Application

The multifunctional Class A power quality recorder is used in single-phase as well as in three-wire and four-wire systems (with neutral conductor). The device is applied wherever comprehensive measurement of supply quality is necessary - at power utilities as well as in industry and trade sectors.
