Monitoring and Protection System for Sensitive Instruments to Power Line Disturbances

In this paper, an intelligent system is designed to measure, record, examine the line voltage disturbance, and to protect sensitive equipment against power line disturbance and using data recorded to selecting a good power prevention policy. Arduino UNO board is used to implement the data acquisition circuit, which send them to a protection system in order to Error handling of power line disturbance. The circuit is acquiring the line voltage and frequency, and then interfaced to a personal computer via USB cable. LabView software program is used as user screen interface and to provide data recording. The data recorded connected with protection circuit to protect instruments lab from disturbances. Also the data recording property allows the user to document the result as selected in text format. The system is successfully tested, and the maximum percentage error obtained in voltage measurement was (0.383%) and in frequency was (0).
