Three Phase & Single Phase Induction Motor Protection System
Three Phase & Single Phase Induction Motor Protection System :
Due to the robust construction and ease of control, three-phase asynchronous motors are widely preferred over many other motors for the AC motor driven applications. This three-phase motor is accountable for larger load operations in several applications like goods and lift hoists, conveyors, compressors, pumps, ventilation systems, industrial fan controllers, etc.
With the invention of adjustable speed drives and several other types of motor starters, three-phase motors have become favorable drives for variable speed applications. As these motors are important in load driving, it is also important to ensure their safety & protection against starting inrush currents, overloads, single phasing, overheating and other faulty conditions. Before going into the details of these motors and their protection systems, let us look on three-phase motor basics.
