Development of Pumping Motor Protection System

Abstract: Day today life get faster and automated to make the day easier. The world on today scenario, They need product that are user friendly and easy to use. Our product is useful in both the industry and home. Water is basic need of life. Ground water and fresh water is key source of water supply.We use motor or water pump to suck the water from the ground. During the summer the ground water level decrease, at that period of time motor cannot get the enough water to pump and it leads to the dry run of motor. Continuous run of motor at dry condition leads to increase in surge pressure, damage in coil, it cause damage in motor. To avoid this by using current sensor we detect the motor at loaded and unloaded condition. At unloaded condition or dry condition after particular period of time the motor will automatically turnoff . At set period of interval it again turn on and check the condition, if the motor is in loaded condition then the motor runs continuously. By this method we can safeguard the motor and avoid from serious disaster.
