The fault rate of Linear Variable Differential Transformer of High-pressure regulating valve in steam turbine is very high. By investigating all units in our company, the mainreasons related to the LVDT coil fault, LVDT core fault, LVDT connecting rod fault are summarized. The application and improvement measures about LVDT are studied. Some solving measures about LVDT connecting rod specifications, anti rotating rod installation mode, double LVDT joint installation, operation alarm rule, installation and inspection programs, and reduction method of valve steam exciting force vibration intensity are introduced.
