Design of the LV protection relay testing panel

Abstract

This thesis represents the theoretical description and practical implementation of the LV asynchronous motor protection and control solution with the usage of ABB UMC100 device – a comprehensive motor controller. The theoretical part of the diploma thesis contains the description of the most common faults happening to the motor which must be resolved, it also contains the different possible ways to control and start the motor and their advantages, as well as information about the UMC100 device itself, its elements and functions. The practical part shows the demo panel assembly for motor protection and control, its structure and parametrization, tests and measurements of the panel functions and parameters.
