A METHOD AND A DEVICE FOR MONITORING THE CONDITION OF A TURBO MACHINERY COMPONENT

摘要

A method for monitoring the condition of a gas turbine component (12) comprises the step of electrically charging the component (12) with high voltage, and monitoring the current needed for the charging. A monitoring device for monitoring the condition of a gas turbine component (12) comprises a charging circuit electrically connected to the component (12) and a current monitor (24) in the charging circuit for monitoring the current needed for charging the component (12).
