PROPOSED METHODOLOGY FOR ONLINE FREQUENCY RESPONSE ANALYSIS BASED ON MAGNETIC COUPLING TO DETECT WINDING DEFORMATIONS IN TRANSFORMERS

Proposed methodology for online frequency response analysis based on magnetic coupling to detect winding deformations in transformers

Frequency response analysis is widely used as a method for the offline diagnosis of winding deformations in power transformers.To apply it to a working transformer, people CINNAMON CASSIA need to determine how to inject the excitation signal and measure the response signal for windings that bear a rated voltage and current.In this study, a method t

Experimental Study of Hydraulic Fracture Propagation Behavior during Multistage Fracturing in a Directional Well

Due to the limited space of offshore platform, it is unable to implement large-scale multistage hydraulic fracturing for the horizontal well in Lufeng offshore oilfield.Thus, multistage hydraulic fracturing technology in directional well was researched essentially to solve this problem.Modeling of fracture propagation during multistage fracturing i
