Abstract
Diploma thesis is focused on a theme – “Protection Settings and Selectivity in Industrial Network”. Content of the thesis include protection settings calculations - mainly, overcurrent and ground-fault protection functions. Also, diploma contains selectivity charts for the equipment used in the given industrial network. Electrical equipment were predefined by a customer and were tested with a load flow calculation in a software. For the protection purposes short-circuit currents were calculated as well.
