Details
The DS200TCTGG1A is a Turbine Trip Board (TCTG) developed by GE.
It controls the fuel shutoff halves for the turbine and is located in position 4 of the core. On the TCTG board, there are two different trip relay types available for failsafe fuel valve functioning.
Primary trip relays (PTRs) and emergency trip relays are both available (ETRs). The PTRs are controlled by the CSP and communication errors.
The ETRs are managed by the TCEA boards in the core, and an emergency trip requires a 2/3 vote.
Pushbuttons for hardwiring trips will turn off the 24 V dc power to the PTR and ETR relays and start a trip. The TCTG board also houses the synchronizing relays.
On the TCTG board, there is only one hardware jumper. The Emergency Overspeed servo Clamp is J1.
Activate the jumper to open servo valves 1-4. Applying 24 V dc to the servo outputs requires the usage of this jumper.
