FIELD: measuring technology.
SUBSTANCE: invention relates to electrical measurement and can be used to assess suitability of newly developed electricity from uncontrolled power selection (theft by unwinding) from power grids. Device for testing of inductive electric meters contains storage capacitors in bridge device branches. Outputs of capacitors with one side are connected to grid conductors, and on other side to thyristor in bridge device diagonal circuit. At that, in series with storage capacitors power diodes and chokes are installed, connected to grid conductors. Thyristor control circuit includes integrating link with controlled time constant of series-connected storage capacitor and variable resistor between anode and cathode thyristor. Storage capacitor is connected to primary winding of step-down transformer via dinistor. Secondary winding of step-down transformer is connected to "control electrode-cathode” transition through in-series connected diode thyristor and limiting resistor.
EFFECT: technical result consists in significant simplification of device control.
