FIELD: electric engineering.
SUBSTANCE: subject commutation device is connected by force output to load input, by force input to joined force outputs of auxiliary commutation device and three-phase auto-transformer. Joined force inputs of the latter are connected through three-phase automatic switch to alternating current network phases. Stabilized power source is connected to network through one-phase automatic switch. First input of control-setting block is connected to output of stabilized power source, second one - to information output of auxiliary commutation device, and third input is meant for connection to subject commutation device. First output of control node is connected to input of pulse counter, second output - to control input of auxiliary commutation device. Third output of control assembly is meant for connection to control input of subject commutation device.
EFFECT: possible automatic detection of commutation durability, possible testing in different modes.
