        Abstract: The overvoltage/undervoltage protective device with auto-reclosing function (OUPA) is a new type of electrical protector recently. This article introduces the classification of protectors OUPA, and elaborates in detail from the working principle block diagram of OUPA, the setting of overvoltage and undervoltage values, the operating characteristic test circuit, and precautions for use. The article points out that from the perspective of market demand, OUPA not only has over- and under-voltage protection, but also has over-current protection, and its application prospects in power protection will become more extensive.
        Key words: overvoltage/undervoltage protective device with auto-reclosing function; action characteristic; characteristics test
