Srovnání experimentálních metod zjišťování oteplení v elektrotechnice.

Abstract

My bachelor thesis is focused on different kinds of methods how to measure a heating of electrical machines and devices. The heating is created by an influence of losses. The losses are theoretically described in the first chapter. Description of different kinds of methods of contact and contactless thermal measuring is located in the second chapter, where are also mentioned advantages and disadvantages of these methods. The practical part consists of the measuring of a temperature on a circuit breaker by thermocamera and thermocouple. These measured values are shown in graphs and are graphically compared. The results, the advantages and the disadvantages of these kinds of methods are discussed in the conclusion of the bachelor thesis.
