Arduino based Low Cost Power Protection System

In this paper, harmonics, noises, reactive power etc. are considered as major concerns. This paper presents the development of simple power quality software for the purpose of protection of any system under fault conditions. By designing virtual instruments using LabVIEW software, the real time data of hardware are fed to the software using Arduino for interfacing with LabVIEW. The software recognizes the different types of fault conditions based on pre set values and indicates the type of fault occurred in system. It also disconnects the equipments on load side. Testing results and analysis indicate that the proposed method is feasible and practical for protection of the system during fault conditions.
