800 MW Transformer Protection Relay

Reliable and safe DGT 801B DIGITAL GENERATOR - Transformer Protection Relay 800 MW

The DGT 801A, DGT 801B, DGT 801C, DGT 801D, DGT 801E, and DGT 801F Protections are the

DGT 801 series products. They are based on a common hardware and software platform except the

number of the hardware sources and the sizes of their respective display panels on the cabinets. The

details can be found in Table 1.1. They all adopt the design of duplicate power supplies and

dual-CPU systems with parallel processing technique. So they are advanced in configuration,

excellent in performance, humanized in debugging and maintenance, reliable and safe in operation.   

The DGT801 series protections adopt a common software platform and each contain all the

protection functions necessary for the 600MW ~ 1000MW generator-transformer units. In a project

configuration, the required protection modules can be flexibly provided through the graphic-defined

software for several relays to pe rform their respective different functions. The several layers would

be combined to implement all functions for the generator-transformer units of the various capacities.
