The Capacitor Testing and Sorting Machine Based on PLC Control Technology

The capacitor testing and sorting machine is used to carry out DC charge-discharge test、DC dielectric strength test、insulation resistance measurement、capacitor and damage factor measurement for box capacitors, and to sort them according to the test result. PLC is used as main controller, in that it can help the machine with fast、accurate test and precise selection. Construction and process of the machine is introduced, also the PLC control system and the program design are described in this paper.
