An Automatic Device for Power Line Quality Test and Life Test of Switch

This article is intended to design an automated device for power line quality and life test. The designs of this device contain three various parts: mechanical system, control and PC software. The control algorithm and the program execution flow will be described in detail in this paper. Using the raspberry pi to control the step motor and to realize the switch of machine on and off is the main purpose. The device can work automatically and be controlled remotely. It works well and it achieves our requirements.
