| Abstract: | CIVA simulation software platform was used to study the eddy current testing of the steam gener-ator tube for nuclear power plant with the differential bobbin coil. With numerical simulation, the optimal frequency of detection of the inner and outer walls of the SG tube defects were determined and the theoreti-cal values were compared. The interval size between the probe coil, the coil width and the circumferential groove defect width were used to study the influence on the detect results. In order to find the correspond-ing orderliness, the numerical simulation result from CIVA is used to analyze, which can supply a very im-portant theoretical significance and practicality for eddy current testing used by differential bobbin coil in nuclear power plant. |
