PURPOSE: An apparatus and a method for inspecting a safety stop operation of a hydraulic actuator for a power plant turbine are provided to specifically inspect the defect of each component and to provide the inspection results of a hydraulic actuator to users through an output unit so that the users can easily grasp the results. CONSTITUTION: An apparatus for inspecting a hydraulic actuator for a power plant turbine(10) comprises a hydraulic actuator(100), multiple sensors, a control unit(400), and an output unit(500). The hydraulic actuator comprises a main body, a servo valve, a solenoid valve, and a shutoff valve. The servo valve selectively changes flow rate provided to the lower part of a piston by changing an inner passage according to input signals. The multiple sensors detect operating information of the hydraulic actuator. The control unit selectively shuts off the input signals provided to the servo valve and processes the operating information detected from the multiple sensors. The output unit outputs results of the operating information processed in the control unit to users. [Reference numerals] (400) Control unit; (500) Output unit |
