Abstract:
With the rapid industrialization and modernization of power sector and increase in demand requires electrical supply without failure. In this regard, it is essential to have adance protection schemes for complete power system. It incorporates frequent swiching losses and has high response time against the faults. In this work, an advance current differential relay for better safety of equipment is presented in which Arduino is programmed like that it takes approximate 200 samples in a complete current cycle through which reliability, accuracy and efficiency of this protection scheme is increased and also it is more flexible for various applications by providing repogramming feature of Arduino.
