GE IS200TTURH1BCC Primary Turbine Protection Input Terminal Board

IS200TTURH1BCC Primary Turbine Protection Input Terminal Board

Functional Description

The Primary Turbine Protection Input (TTURH1B) terminal board works with VTUR and has the following inputs and outputs:

• Twelve passive pulse rate devices sensing a toothed wheel to measure the turbine speed

• Generator voltage and bus voltage signals from potential transformers 

• 125 V dc output to the main breaker coil for automatic generator synchronizing 

• Inputs from the shaft voltage and current sensors to measure induced shaft voltage and current

TTUR has three relays, K25, K25P, and K25A, that all have to close to provide 125 V dc power to close the main breaker, 52G. The speed signal cable to VTUR uses the JR5 connector, and the other signals use the JR1 connector. For TMR systems, signals fan out to the JR5, JS5, JT5, JR1, JS1, and JT1 connectors.

Mark VI Systems

In the Mark* VI system, the TTUR works with the VTUR processor and supports simplex and TMR applications. In TMR systems, TTURH1B connects to three VTUR boards.

Mark VIe Systems

For the Mark VIe system, a new design board, the TTURH1C, is used.
