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:
1. Standard signals
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...
