Abstract
The bachelor thesis deals with 3-f breakers, which are used for routine protection, for example in households.
The first part covers what different parts of the breaker is made of so that its functionality is not limited. Further more we learn about its fuctionality of protection circuits. We will also learn about tripping characteristics of circuit breakers which is the aim of later years.
Furthermore we will move to the actual implementation of a workplace for 3-f breaker. In this chapter I will describe assembly of the measurement product, what material was used for its production and how the linking was done. I will also describe a possible measuring method, meaning what integration has been chosen for the given product and what deficiencies had to be solved during the product testing.
