Abstract
In nuclear power plants, pressurized sensing lines are used to locate sensors and transmitters away from the main functional equipment. These lines can be affected by leakage, blockage and void. In previous work, the equivalent pi circuit is used to model and analyze the sensing line and the fault conditions. This paper extends the research to more types and detailed fault conditions including blockage at a particular location along the sensing line and a void along a significant length of the line, which better resemble real world cases. The frequency responses of each condition are represented with pressure transmitters included. Furthermore, these fault conditions are explored for better understanding the fault behaviors to reveal a fault at an earlier stage and detect the location and magnitude of the fault as well as differentiate these fault types.
