The performance test of motor control and protection device is the key of research,adjustment,producing and ex-fac-tory verification. The design of a new automatic test system consisting of industrial computer,self-designed test signal source which in-cludes high precision AC power with stable current supply,AC voltage source with adjustable amplitude and phase,data acquisition board,signal modulating board and software developed by using LabVIEW virtual instrument technology was introduced. The system could satisfy the demands of motor control and protection device ex-factory test. The system could be used to test five products at one time. The type and model of test product could be identified by RS485 communication,and various parameters of motor control and protection device could be tested automatically. The realization and functions of the automatic test system were also introduced in detail from the hardware structure and especially the software function. The system has the following properties,such as high precision, strong disturbance attenuation,high efficiency and convenience manipulation.
