INPUT-METERING AND DISTRIBUTION DEVICE WITH THE ABILITY TO CONNECT A GENERATOR AND AN AUTOMATIC FREQUENCY UNLOADING FUNCTION Russian patent published in 2021 - IPC H02B1/00 H02B13/00 H02J4/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to input-accounting and distribution devices. The effect is achieved by the fact that the device allows for manual and remote switching of the consumer's network, monitoring the amount and duration of deviations of the power quality indicators at the consumer's input, identifying the reasons for disconnection of switching devices installed in the input-metering and distribution device, automatic restoration of the consumer's power supply after outages, preventing, if necessary, unauthorized supply of voltage from the consumer's network to the general network, ensuring the possibility of connecting the generator, which is on the consumer's balance sheet, to the general network, or only to supply the consumer's loads, allows the consumer's loads to be divided into two or more groups, carries out the functions of protection against sparking, carries out the functions of automatic frequency unloading.

EFFECT: expanding functionality, providing the possibility of dividing the load into two or more groups and providing protection of the consumer's network from arcing.
