🔍 Key Concepts

• Carefully study the legend at the bottom of illustration GT-0006 that identifies the symbols for T 5.4 thermocouple probe ports versus other probe/inspection ports. • Recall how multiple gas‑turbine exhaust thermocouples are typically wired to obtain an average exhaust gas temperature (EGT) reading (series vs. parallel connections). • Look closely at how many wire bundles/harnesses are drawn leaving the turbine area and how many individual probe locations they serve.

💭 Think About

• From the turbine mid‑frame circle, how many T5.4 thermocouple probe symbols can you count, and do they appear to be grouped in any way around the circumference? • Does the illustration show one output signal, several separate signals, or groups of probes feeding a smaller number of cables/harnesses? What does that suggest about whether the connection is series or parallel? • If the goal is to protect the turbine using an average temperature, which wiring method (series or parallel) would more naturally provide a single representative value instead of many separate readings?

✅ Before You Answer

• Verify the number of T5.4 thermocouple probe ports shown in the turbine mid‑frame detail and compare it with the numbers mentioned in the answer choices (12, 2 harnesses, 4 harnesses). • Check how many distinct harness bundles are drawn leading away from the thermocouple area, and match this to the options that mention 2 harnesses vs. 4 harnesses. • Confirm, from your turbine/thermocouple theory, whether a parallel connection tends to give an averaged temperature signal or multiple independent signals, and whether a series connection tends to give summed voltages or individual readings.
