Induction motor is rotating type of electro-mechanical device. Induction motor convert electrical energy into mechanical energy. Induction motor is highly reliable, require less maintenance and have high efficiency. Induction motor are wide in range of operation and it used in many application because its construction is simple and robust. In past induction motor can be protected by manual operation of component such as timer, contactor, electromagnetic switch, voltage and current transformer. Protection of an induction motor against problem such as short circuit, temperature rise, single phasing and motor vibration occurring in the operation is very important. Manual operation of protection system are very slow and is not accurate. Looking to this issues, in this paper PLC based protection method is used. Which operated automatically, provide higher accuracy and quick response.
