SYSTEM OF DISTRIBUTION OF ELECTRIC POWER Russian patent published in 2008 - IPC H02J1/00 G01R27/16 

FIELD: electricity.

SUBSTANCE: system contains a power unit, connected to its output lines of the switchboards of circuits of the feed circuits of instruments and the control unit of the switchboards, the additional switchboards, connected to the output lines of the power unit, which through the first and second resistors with identical ratings are connected with the first input of the control-measuring equipment and on the case ("ground") of the article, and through the third and fourth resistors with identical ratings - with the second input of control-measuring equipment, the simulator of insulation resistance of the inputs is connected to the outputs of additional switchboards, and by a common point is connected to the case ("ground") of the article, thus the simulator is executed in the form of additional resistors whose first outputs are connected to its inputs, and the second outputs are connected to its common point.

EFFECT: increase in the operational reliability of the distribution system of electric power by guaranteeing of reliable control of insulation resistance of the system and the equipment fed by it.
