Automatics devices for digital substations
The devices ensure automation of digital substations meeting the requirements of the international standard IEC 61850: automation of electric power transmission and distribution, operation of relay protection and automatics systems, recording of emergency events.
Arc protection devices
ImPR1_ESHubU-1 switching unit with ImPR1_ESensU-1 optical sensors is designated to detect a short circuit arc in distribution devices in a short period of time and to transmit information on a monitored section into relay protection and automatics devices.
Current and voltage sensor
The PSensU-1 current and voltage sensor is designated to measure and monitor current up to 6 kA and voltage up to 6.5 kV and to transmit data via fiber-optical channels into a protection device.
Low-voltage switchgears NKU RTZO-I
Low-voltage switchgears are three-phase alternating current distributors of closed version, one-way service are designated to distribute electric power to low-power users.
Input panel ShchV-1
The panel is designated to input, protect against impulse lightning overvoltages, and record electric power consumption of three feeders of three-phase voltage depending on the package.
Distribution cabinet ShR-1
The cabinet is designated for connection of 21 users (with rated power 880 V·A each) to a power network by means of automatic switches from two independent feeders.
