Abstract :
This paper presents a design and implementation of two current relay prototypes. The first one is based on FPGA. It protects against over-current, phase loss and locked rotor. This design is implemented, downloaded and tested on Altera Flex 10k10LC84-4 device. The second prototype is microcontroller based multi-function relay, it protects against over-current, undercurrent, phase loss, locked rotor, phase unbalance and ground fault. This design is implemented and tested on Atmel microcontroller ATMega 16PC035II. Finally, both prototypes specifications were referenced to SMWAHA EOCR-Schneider electric protection relays EOCR-SS and EOCR-3EZ respectively according to the European and Korean standards.
