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
