A Non-Invasive Tunable Current Circuit Breaker (TCCB) for Motor Protection in Industries
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
In the case of industries, once a power system is established, it is essential to protect the equipment from faults. The major portion in total load is occupied by motor load and protection of motor by Motor Protection breakers from faults is mandatory. Generally, Motor Protection breakers cannot be adjusted to match the rated current of the motor being protected. They usually made with fixed ratings which can be chosen according to the requirement. The proposed Tunable Current Circuit breaker (TCCB) can be adjusted for the different value of rated current. High tension (HT) transformers are critical and expensive equipment in the power system. Due to the long lead time for repair and replacement of the motor and HT transformers, there is a need of protection to avoid damage. Any extended operation of the motor under abnormal condition like faults or overloads reduces the life of the motor. Adequate protection should be provided for earlier isolation of the motor under such conditions. The TCCB can be used for single phase and star or delta connection of three phase motors. When the motor consumes more than the fixed value, immediately TCCB will be tripped. Since it measures current Non-invasively, the power consumption is low and easy to connect. Because of usage of Analog method, the cost becomes low. It provides safe disconnection in the event of a short circuit and protect load from overloading without usage of any electromagnetic component.
