IS200TTURH1BEC Primary Turbine Protection Input Terminal Board
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.
Installation
Connect the wires for the magnetic pick ups, shaft pick ups, potential transformers, and breaker relays to the two I/O terminal blocks TB1 and TB2, as shown in the figure, TTUR Terminal Board Wiring. Each block is held down with two screws and has 24 terminals accepting up to #12 AWG wires. A shield termination strip attached to chassis ground is located immediately to the left of each terminal block.
Use jumpers JP1 and JP2 to select either SMX or TMR for relay drivers K25 and K25P. If used, connect the wires for optional TTL active speed pick ups to TB3; these require an external power supply.
Simplex systems use cable connectors JR5 and JR1. TMR systems use all six cable connectors.
