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

The source of alternating current and voltage three-phase programmable is designed for formation of three-phase or single-phase system of currents and voltages, fictitious power in accordance with the programmable digital signal model. The source is used for verification of measuring instruments: electricity meters of all types PCE analysers in accordance with GOST 30804.4.30-2013 and GOST 30804.4.7-2013; measuring transducers of electric power quantities electrical measuring devices (U, I, cos ?, P, R, S, THD, F) The source generates: <ol> <li>Standard signals</li> </ol>Sinusoidal symmetrical three-phase signal (phase-to-phase angles 120°, nonlinear distortion factor not more than 1 %, value variation not more than ±0.03 %/min). In this mode the following parameters are set: frequency of the first harmonic (from 42.50 to 70.00 Hz in steps of 0.01 Hz) values of phase shifts between currents and voltages for all phases (from -179.99° to +180.00° with a step of 0.01°) values of voltages (from 1 mV to 264 V in steps of 1...
