WIRING DEVICE AND METHOD OF ITS OPERATION Russian patent published in 2011 - IPC H02H3/00 H02H5/12 

FIELD: electricity.

SUBSTANCE: in a proposed wiring device (1) for operation of a power grid (2) for supply to loads, there is at least one first breaker (3) for disconnection of at least one first load (4) and/or a part of the grid (30) from the power grid (2) of supply to loads, at least one first sensor (5) to detect at least one first physical value induced by the power grid (2) of loads supply or exposed to it, and at least one first actuation unit (6), which, as the specified first limit value of actuation is exceeded due to a proportional measured value, disconnects loads from the power grid (2) during the first time of actuation of the first breaker (3), and also at least one first unit (7) of control and monitoring, which comprises at least one timer for the specified and automatic matching of the first limit value of actuation and/or the first time of actuation, depending on at least one control parameter.

EFFECT: increased level of safety and high availability of the grid for operation.
