FIELD: electrical engineering.
SUBSTANCE: invention relates to the field of electrical engineering and can be used to protect the cell of switch gears in 6–35 kV networks. Voltage measuring transformer and the non-linear overvoltage suppressor are connected to the mains via a common fuse, designed to protect the voltage measuring transformer and the non-linear surge suppressor.
EFFECT: technical result is to provide protection against overload and short-circuit currents with one common fuse and a voltage measuring transformer and an overvoltage limiter non-linear without changing the dimensions of the switchgear cell, as well as providing the possibility of determining the operation of a common fuse for the absence of indications of devices included in the circuit of the measuring voltage transformer.
