In this study, the simulation and measurement technique is integrated to apply for the design of operating maintenance system of rolling steel factories. In the method, thanks to the complete visualization simulation module along with the satisfactory computation performance, the wavelet transform as well as Park’s transform were carried out to monitor the transformer inrush current and various disturbances of distribution systems. Meanwhile, the virtual instrument system aided by hardware measurement modules and digital signal processing techniques were also embedded into the proposed system, by which the measurement data were analyzed thoroughly. From these test outcomes, they are deemed useful to support the feasibility of this proposed approach.
