REP Holding awarded a contract for manufacture and supply of 36 relay protection cabinets for the construction of the power plant units № 1 and № 2 of the Kursk NPP-2. The relay protection cabinets designed for the switchgear 330 kV and power transformers of the nuclear power plant will be manufactured at the Elektropult Plant. The equipment supply is scheduled for the 2nd quarter of 2019.
The relay protection and automation terminals are installed in the repay protection cabinets, which are designed to quickly identify and isolate damaged elements from the electric power system. Relay protection provides continuous monitoring of the technical condition of individual controlled elements of electrical power system.
Microprocessor relay protection devices (MRPD) as a part of the relay protection cabinets, in addition to the designated purpose, are used as low-level devices through which the control and monitoring system of the electrical part with the controlled objects interact. At the same time, they perform the functions of collecting data on the current state of electrical equipment, retransmitting commands of remote and automatic control, self-diagnostics, maintaining a single astronomical time for recording emergency events, including recording fast-flowing processes.
