IS200TTURH1A is a Primary Turbine Protection Input Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Primary Turbine Protection Input 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.
INSTALLATION:
TTUR Terminal Board Wiring: Connect the shaft pick-ups, magnetic pick-ups, breaker relays, and I/O terminal blocks TB1 and TB2 to the terminal boards. There are 24 terminals on each block, which may accept wires up to #12 AWG, and they are each attached with two screws. A shield termination strip linked to the chassis ground is located directly left of each terminal block.
OPERATION:
Turbine speed can be determined in simplex applications using up to four pulse rate signals. Along with VTUR, the turbine controller, and the excitation system, the generator and bus voltages are fed into TTUR for automatic synchronization. The main breaker relay coil, 52G, is controlled by TTUR, which also has permissive generator synchronizing relays.
