Device and method for detecting inter-turn electromagnetic pulse vibration wave characteristic of turbogenerator rotor winding

A device and method for detecting an inter-turn electromagnetic pulse vibration wave characteristic of a turbogenerator rotor winding are provided. A signal source and a time sequence control circuit generate a high-potential abrupt electric field; circularly polarized electromagnetic waves generated by a parasitic inductive power supply and symmetrically deflecting by 180° are respectively coupled to a positive electrode and a negative electrode clockwise or counter-clockwise; a first turn on the positive electrode and a first turn on the negative electrode are mutually induced; as time goes by, energy is returned to the parasitic inductive power supply, and is sequentially conducted to a second turn; the parasitic inductive power supply and the second turn further start feeding back energy to the first turn in circular polarization; all turns sequentially perform feedback and superposition one another stage by stage; and all coupling turns show sinusoidal waves with a same time constant.
