Abstract: With the design of data acquiring system and the application of LabVIEW. A testing platform for reliability of AC contactor is designed. The basic theory, the idea of design, the way of application of the platform and the technology of virtual instruments are introduced. The results of experimentations show that the data acquiring system introduced in the paper can achieve real-time sampling and data analysis for the operation process of contacts of AC contactors. Technique item for the operation reliability is proposed according to the contact variety and time difference.
