Měření vypínacích charakteristik digitální ochrany

Abstract

In my thesis, I dealt with the issue of tripping curves protection management SPAA 341 C (module SPCJ 4D28). At first I was acquainted with the principle functions of each type of protection. What are the requirements for the protection and where we can use, or where most of the species occur to protect the wiring. I specifically focused on the issue of overcurrent protection and management requirements on them. Later on, I was acquainted with line protection SPAA 341 C and its modules SpPCJ 4D28. The important thing was to study the settings for individual characteristics, which I later measured. Finally, there was the very measurement for the protection, where I measured the dependent and independent characteristics and patterns are given by the relative error, if it is within the specified tolerances.
