SHE1111A type cabinets of the complex of unified protections of generators, transformers and generator-transformer units of nucl

The protection complex is designed to protect generators, including those operating on busbars, transformers and turbine generator-transformer units of small, medium and large capacity (up to 1800 MW), including those operating in the synchronous compensator mode, as well as to control the generator circuit breaker (or TCN of the unit).
The protection complex is designed as two mutually redundant autonomous protection systems (the first and the second sets of protection). Each set is independent on circuits of operating supply voltage, input and output circuits, signalling and control circuits.
