Which relay indicates entry into a single shot GT?

• A. SH relay
• B. TR relay
• C. R relay
• D. SR relay

Answer: (A)

The SH relay is specifically designed to indicate entry into a single shot GT (Gas Turbine). In the context of gas turbine operations, relays serve various functions to control, monitor, and signal different conditions and statuses of the system. The SH relay performs the crucial role of signaling when the turbine has reached a certain point or condition in its operation, usually following a triggering event that marks the start of the GT cycle. This relay is integral to the control logic of single shot operations, ensuring that the necessary parameters are met for optimal performance and safety of the gas turbine. The naming convention of relays often reflects their function, and in this case, the "SH" designation typically relates to "Start Hold" or a similar operational function relevant to entry conditions. Therefore, in recognizing the role of each relay type, the SH relay stands out as the correct choice for this specific indicator.
