Programmable Three-Phase AC Voltage and Current Source "Energoforma 3.3" for Industrial Testing

The source of alternating current and voltage (fictitious power) carries out formation of three-phase or single-phase system of currents and voltages according to the programmable digital model of a signal. It is used at verification of measuring instruments (MI) of active, reactive and total power and energy (including electric meters); during verification of MIs of electric power quality indicators (EQI) in accordance with GOST 30804.4.4.30-2013 GOST 30804.4.7.7-2013; at verification of measuring instruments of effective value of voltage and current of industrial frequency. Features harmonic composition of the signal - up to the 50th harmonic and 50.5 interharmonics; capacity of the library of signal waveforms simulating characteristic distortions of alternating current occurring in electric networks of various consumer groups - not less than 200 waveforms.
