Capacitor performance detecting system

The utility model discloses a capacitor performance detecting system, which comprises a detector for detecting the capacitance of a capacitor to be detected and a host computer, wherein the detector has a data output port; and the host computer is connected with the data output port of the detector through a self-prepared data input port. After being fixed by a clamp, the capacitor to be detected is connected to the detection port of the detector through a circuit; data acquired by the detector are output to the host computer through the output port; and the host computer, which is configured with data identification and preparation programs, can output the acquired data in an expected format. When the capacitor performance detecting system disclosed by the utility model is used, a process of recording data and manually entering the data into a computer is saved when the capacitance of a capacitor product is tested, test data can be imported into specific tables of the computer directly and managed according
