Patent ID: 8441264

Claim:
A detecting station of a winding product, comprising: a pulse generating module, coupled to the winding product to input a high voltage pulse to two ends of a winding of the winding product; an extracting module, coupled to the winding product for extracting a voltage value of an electrifying process of the winding according to a voltage shunt approach, and generating an extracting data; and a time-frequency analysis module, coupled to the extracting module for performing a time-frequency converting operation to the extracting data to obtain a time-frequency analysis information indicating whether or not an inter-turn short circuit is occurred in the winding of the winding product, wherein when the inter-turn short circuit is occurred in the winding of the winding product, the obtained time-frequency analysis information comprises a high frequency energy concentration at a specific time point, wherein when the inter-turn short circuit is not occurred in the winding of the winding product, the obtained time-frequency analysis information does not have any obvious high frequency energy concentration at any time point.
