Selektivní střídavý milivoltmetr

Abstract

This diploma project deals with modernization of selective AC millivoltmeter from EGÚ Brno, a.s. To understand the subject, it roughly explains the theory of voltage potential and because this device is going to be used in electrical substations this document also explains basics of dangerous situations and errors which can occur in the area of mentioned electrical substations. This project then moves to the millivoltmeter itself where it explains the functioning of each individual part, improves the original design, justifies the use of new components dependant on set requirements and defends innovations that have been added to the device for user comfort. This project also contains a self-explained documentation for designed device for users or future changes.
