| Abstract: | Partial discharge monitoring is one of the main methods to inspect the cables' status.An online monitoring and diagnostic new method to inspect XLPE cables' partial discharge based on Feedback Terminal Unit(FTU) is established.The improved Rogowski coil sensor is used to overcome the disadvantage of low bandwidth,and WAN is used to send the signal based on FTU.The experiment done in this paper proves that this system has wide bandwidth,small size and convenient real-time signal transmission advantages. |
