DGT 801F:482.6mm(length)×370.0mm(depth)×266.0mm(height) 

Ambient temperature: -10ºC ~ +55ºC 

Relative humidity: 5%~95%   

Atmospheric pressure: 70Kpa~106Kpa

 

2)  Rated electric parameters 

Supplementary AC power supply of the printer: 

Voltage: 220V,  permissive variation: -15% ~ +10% 

Frequency: 50Hz or 60Hz 

DC power supply: 220V,  110V,  permissive variation: –20% ~ +15% 

AC current: 5A,  1A; frequency: 50Hz or 60Hz   

AC voltage: 100V,   3 100 V; frequency: 50Hz or 60Hz 

3) Power consumption 

AC current circuit: <0.5VA/phase 

AC voltage circuit: <0.25VA/phase (as U=Un) 

DC power supply circuit: <50W (normal); <80W (protection operation) 

4) Over loading capability  

AC current circuit :    2 In—The long-time operation is permitted. 

30 In—10s operation is permitted. 

50 In—1s operation is permitted. 

AC voltage circuit :    1.5Un—continuous operation. 

DC power supply circuit (80%~115%) Un—continuous operation.

 

5) Insulation capability

Insulation resistance: Under the standard test  conditions, the insulation resistance between
every circuit and the shell of  the protection or between such  circuits without electrical
connection is not lower than 100MΩ .
„  Media strength: Between every circuit and the shell  of the protectation or between such circuits
without electrical connection, the 50Hz, 2kV(RMS) and 1 min. test can be tolerated without
insulation break downs and flashovers.   
Impulse voltage: Under the standard test atmospheric conditions, the DC power supply input
circuit, AC input circuit, output contact circuit  to the ground of the protection and between all the
circuits can tolerate the short-duration impulse voltage test of 1.2/50us standard lighting waves.
The open voltage is 5kV and no insulation damages will occur.

 

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.
