Abstract
Dandanes je tržišče preplavljeno z raznoraznimi električnimi in elektronskimi krmilniki. Hitrost s katero novi krmilniki prihajajo na tržišče le še narašča. Potrošniki jih vse pogosteje uporabljamo za vsakodnevna opravila, kot so na primer brezžično, daljinsko ali samostojno upravljanje s svetili, senčili, ter varnostnimi in zalivalnimi sistemi. Vsi krmilniki morajo pred začetkom prodaje na tržišču prestati ustrezne preskuse in pridobiti certifikat. Mnogokrat se med postopkom certificiranja izkaže, da so prav preskusi segrevanja Ahilova peta proizvoda. Diplomsko delo v uvodnih poglavjih predstavi področje standardizacije in delovanje termočlenov. Sledi opis zahtev in postopkov preskusov segrevanja avtomatskih električnih krmilnikov, skladno s standardom IEC 60730-1. Mednje sodijo preskusi segrevanja proizvoda, preskusi s kroglico z utežmi in preskusi z žarečo žico. Vsak izmed omenjenih preskusov je bil tudi praktično izveden in opisan. Na koncu je opredeljena merilna negotovost vseh treh preskusov segrevanja.

Title:Automatic electric controllers heating tests
Abstract:
Nowadays, the market is flooded with a variety of electric and electronic controllers. The rate at which new controllers hit the market is only increasing. Consumers are increasingly using them for everyday tasks, such as wireless, remote or independent control of lights, shades, security systems and watering systems. All controllers must pass appropriate tests and be certified before being sold on the market. Many times during the certification process, it turns out that the heating tests are the Achilles heel of the product. In the introductory chapters, the thesis presents the field of standardization and operation of thermocouples. It is then followed by a description of the heating test requirements and procedures for automatic electrical controls in accordance with the IEC 60730-1 standard. These include product heating tests, ball pressure tests, and glow-wire tests. Each of the mentioned tests was also performed and described. Finally, the measurement uncertainty of all three heating tests is defined.

Keywords:automatic electrical control, product heating test, ball pressure test, glow-wire test, measurement uncertainty
