Determining the remanent magnetic flux of a power transformer using a low power DC source

U ovom radu definiran je remanentni magnetski tok, navedeni su primjeri iz prakse u kojima je važan utjecaj remanentnog magnetskog toka i opisane su neke od metoda za određivanje remanentnog magnetskog toka. Detaljno je opisana metoda za određivanje remanentnog magnetskog toka istosmjernim izvorom male snage, laboratorijski postav i mjerni postupak. Rezultati mjernog postupka prikazani su odgovarajućim slikama i vrijednostima prikazanim u tablici.In this paper, residual magnetic flux is defined, examples from practice are given in which the influence of residual magnetic flux is important, and some of the methods for determining remanent magnetic flux are described. A method for determining the residual magnetic flux using a low-power direct current source, laboratory setup and measurement procedure are described in detail. The results of the measurement procedure are presented with the corresponding figures and values shown in the tabl
