Abstract:
Electric motors are important part of modern power systems, located at the demand side and ensuring that a number of industrial processes are delivering their prescribed duty, e.g. to pump water run air conditioners, or to enable manufacturing of a number of products etc. As an element of the system with a rotor, it can have a number of complex faults needed to quickly and selectively eliminated. Different types of motors are protected by different types of protective devices/functions.The understanding of motor protection relies on understanding the nature of motor faults. The lecture will present the most important aspects needed for designing motor protection: the nature of motor faults, motor characteristics and models, as well as the major motor protection functions. Some illustrative examples from laboratory testing will be presented, too. Particular focus will be put on thermal processes and motor starting characteristics.
