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 signal model.
It is used
- at verification of measuring instruments (MI) of active, reactive and total power and energy (including electric meters);
- at verification of measuring instruments of electricity quality indicators (EQI) in accordance with GOST 30804.4.4.30-2013 GOST 30804.4.7-2013;
- 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 forms simulating characteristic distortions of alternating current arising in electric networks of different groups of consumers - not less than 200 forms.
