Recently observed that the conventional method used for protection for three phase induction motor is taking time to operate and the cost of the system is high. So to overcome this, there is need of a protection system which can operate in less time and has low cost. The mission is to create a system which has slow cost and fast operation. This condition gave the basic idea about what was required in current Scenario. The idea was to create a system which is cheap and will reduce the operation time. The system has the ability and the economic value to for fulfilling the protection of three phase induction motor. This system is cost effective and easy to maintain. This paper addresses to make a cheap and reliable protection system for three phase induction motor. The protection system should protect the motor from voltage unbalancing, single phasing, under voltage, over voltage and thermal protection. To improve the technique to run the motor below single phasing. Taking the cost factor into consideration the design has been proposed using Arduino, relays, small CTs and PTs. However the sensitivity of the protection scheme has been not compromised.
