APPARATUS FOR IMITATING CURRENT LOAD WHEN TESTING LOAD SWITCHING EQUIPMENT Russian patent published in 2013 - IPC G01R31/327 

FIELD: electricity.

SUBSTANCE: apparatus has a dc voltage supply source (1) connected to the equipment (2) to form a first loop, and voltage source connected to the equipment (2), the value of which is less than the voltage of the supply source (1), which is made in form of two dc secondary supply sources (3) and (4). Source (3) is connected to the negative terminal (5) of the equipment (2), which is meant for connecting a switched load (6), and to the negative terminal (7) of the power circuit of the equipment (2) to form a second loop. The second source (4) is connected to the positive terminal (8) of the equipment (2), which is meant for connecting the switched load (6), and to the positive terminal (9) of the power circuit of the equipment (2) to form a third loop.

EFFECT: reducing power of the supply source and enabling imitation of current loads in the power circuit of controlled equipment.
