Abstract
A gas turbine engine comprises a hot section module which includes at least one electric probe assembly surrounded by an immediate environment having a local ambient temperature. The at least one electric probe assembly includes an electric probe having a probe body, and a conduit surrounding at least a portion of the probe body. In operation, the conduit carries a fluid flowing at a temperature lower than the local ambient temperature. The at least portion of the probe body is embedded in the fluid inside the conduit. The fluid thermally insulates the probe body from the local ambient temperature of the immediate environment around the at least one electric probe assembly.
