Combustion dynamics monitoring ignition system for a gas turbine

A combustor (102) including a casing (104) surrounding a combustion zone (106), and an ignitor plug (108) including a tip (110), a base (112), and a body (114) extending therebetween, the body (114) extending through the combustor casing (104) such that the tip (110) is proximate the combustion zone (106), the ignitor plug (108) configured to receive ignition energy through the base (112) and generate an ignition source at the tip (110), the ignitor plug (108) further configured to sense combustion dynamics in the combustion zone (106) and generate a signal relative to the sensed combustion dynamics.
