Generator Protection Unit Type SHE111H for Reliable Protection of Generators and Transformer Units

The protection complex is designed for protection of generators, including those working on busbars, transformers and turbine generator-transformer units of small, medium and large capacity (up to 1200 MW), including those working in the synchronous compensator mode, as well as for control of the generator switch (or TCN of the unit). The complex of protections can also be applied for generators - engines of hydroelectric power plants. The protection complex is designed in the form of two mutually redundant, autonomous sets of protection (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.
