Development of fast electronic over-current protection circuit using current-adjustable sensing method [PDF]
Traditional methods to protect the electric-driven facilities from overload or short circuit usually use electronic breaker or fuse. However, the reaction time for these devices normally require more than 0.1 s that may be not sufficiently fast to ...

Automatic Speed Control of Motor with Over Current and Thermal Protection
This paper aims to design a controller to minimize the accidents of mechanical failure of industrial generators and motors under heavy load or malfunction. The controlling parameters such as the speed of motor is done via controlling the voltage and current fed to the motor. The speed control can be possible by using PWM technique.
