Performace test system for control rod coils

The present design relates to whether the reactor control rods coils of health or age are used in nuclear power plants in the systematic and fast, rod coil system diagnostics to ensure accuracy. Control rod coil diagnosis system according to the present invention is connected to the control rod and an electrical coil, a measuring unit which measures an electrical characteristic of the coil control rod; It includes and is electrically connected to the measuring unit, the diagnostic section for diagnosing the abnormality of the control rod coils to control the operation of the system, and using the measured values ​​for the above electrical characteristic of the control rod coil measured by the measuring section do. Wherein the measuring unit by using a Wheatstone bridge circuit in order to improve the effect of hunting (hunting) in accordance with the type of control rod coil measure the DC resistance of the control rod coil, or by using an LCR meter DC resistance, flow resistance, the inductance and quality factor (Q-factor) value is measured. May further measure the electrical characteristics of the plurality of control rods at the same time, the coil including DRPI card and relay card array for connecting a plurality of control rod coil in the measuring part. Wheatstone bridge rod coils diagnostic system, (Wheatstone Bridge), Hunting (Hunting)
