摘要：
A system for detecting defects in a turbine rotor blade of a combustion turbine engine. The system may include: a turbine rotor blade that includes an insulator coating; a first electrode that is electrically connected to the turbine rotor blade; a second electrode that resides in proximity to the turbine rotor blade; means for inducing a voltage across the first electrode and the second electrode; and means for detecting current flowing between the first electrode and the second electrode.
