| Abstract: | In recent years,CVT with high fault rate and fast fault development,often lead to equipment accidents due to no effective monitoring methods.This article introduces common failures and features of CVT,proposes to find CVT's defects and failures at early stage by on line monitoring the secondary voltage variation of CVT's to prevent occurrence of equipment's accidents.It also proposes monitoring criteria and methods.The reliability of CVT improved significantly after using the secondary voltage on-line monitoring. |
