Abstract
Transformator je uređaj koji pretvara izmjeničnu struju zadanoga napona u izmjeničnu struju višeg ili nižeg napona i kao takav ključan je u prijenosu električne energije od proizvođača do potrošača, jer smanjuje gubitak energije. Svaki transformator u sebi sadrži ulje koje služi kao izolacijska i rashladna tekućina, a uz to ulje daje informacije o kvaliteti transformatora. S vremenom transformatorsko ulje oksidira i postane onečišćeno, a sve to se odražava na kemijska i fizikalna svojstva ulja što u konačnici stvara nekvalitetno ulje za rad transformatora. Postoji tri vrste ulja koja se koriste u transformatorima, a to su mineralna, silikonska i esterska. U ovom radu koristila su se mineralna izolacijska ulja, osam uzoraka s područja Slavonije. Svrha ovog rada je proučiti metode kojima se određuje kvaliteta transformatorkog ulja, usporediti njihove rezultate i na temelju svih rezultata donijeti zaključak o ispravnosti ulja. Naglasak je na metodama određivanja refrakcijskog indeksa i boje ulja.
Abstract (english)
A transformer is a device that converts alternating current of a given voltage into alternating current of higher or lower voltage and as such is crucial in the transmission of electricity from the producer to the consumer, because it reduces energy loss. Each transformer contains an oil that serves as an insulating and cooling liquid, and in addition the oil provides information on the quality of the transformer. Over time, transformer oil oxidizes and becomes contaminated, all of which is reflected in the chemical and physical properties of the oil which ultimately creates poor quality oil for the operation of the transformer. There are three types of oils used in transformers: mineral oil, silicone oil and ester oil. In this work are used mineral insulating oils, eight samples from the area of Slavonia. The purpose of this final work is to study the methods used to determine the quality of transformer oil, to compare their results and on the basis of all the results to draw a conclusion about the correctness of the oil. The emphasis is on methods for determining the refractive index and oil color.
