Abstract
A motor protector and a method for operating the same. The motor protector includes: a power supply unit adapted to receive electric power from power supply lines of a motor to power the motor protector; a measuring unit adapted to measure electric parameters of the motor; and a controller configured to at least perform steps of: receiving from the measuring unit the electric parameters; determining, based on the electric parameters, whether the motor experiences a first failure related to overheating of the motor; enabling, in accordance with determination of the first failure of the motor, the power supply unit to power a closing mechanism of the motor protector after a predetermined time, thereby closing the closing mechanism to power the motor by the power supply lines; determining, based on the electric parameters, whether the motor experiences a second failure different from the first failure; and enabling, in accordance with determination of the second failure of the motor, the power supply unit to stop powering the closing mechanism. Hence, the motor protector can discriminate types of the motor failures and adopt corresponding measures for different failures.
