IoT Based Pilot Wireless Differential Relay

Differential relays are simple, reliable and widely used type of protection scheme that are very much suitable for electrical system or equipment protection. The relays use pilot wires to find the ‘difference’ but the pilot wire itself creates so many problems. To eliminate the problems, in this paper an IoT based wireless current differential protection system is proposed based on Wi-Fi communication and is implemented as a small project work and has also been tested for the protection of a pseudo power system network. The work done here is a small project but with a small update this can be used for real life power system protection.
