Abstract: In this paper a laboratory setup has been developed that mainly focuses on implementing the multi-functional numerical relay for the purpose of single phase online fault detection to protect the electrical equipment’s against overvoltage, over-current and under-voltage faults. The developed system is highly responsive, and user friendly. The fault parameters values were made adjustable by the use of dedicated on-board tactile switches. The system keeps on comparing the values of over/under-voltage and over-current with that of the reference current/voltage values and takes the decision of isolation in real-time by shutting down the relay circuit immediately if any of the reference limits would cross. Hardware prototype with LPC812 as core controller is built to validate the operation.
