1. a gas turbine (3), it comprises igniter (340), cable (335) from actuator (330) to igniter (340), this cable is transferred to igniter (340) to electric energy, first conductive shield (345), and this cover is round cable (335) and be connected to motor, with second conductive shield (350), this covers from external conductive cover (345) extension and round igniter (340), a kind of method, and this method comprises:

  • A) keep a sensor in connection with igniter (340) (310);

    B) detect first conductive shield (345) or second conductive shield (350) both one of in current pulse, perhaps the current pulse among both is all detected;

    C) when detecting current pulse, send the signal that the expression electrical spark exists.
