Analysis of Inter-phase Short-circuit Accident of S11-5000/35 Box-type Transformer
This paper is focused on an exemplary case of inter-phase short-circuit fault encountered by a S11-5000/35 box-type transformer in an actual wind farm,it analyzes and investigates the cause of the accident,and ultimately determines the fault type as inter-phase short-circuit discharge.It then proposes corresponding solutions and preventive measures.
