Jedra iz mehkomagnetnih materialov - Merilne metode - 3. del: Magnetne lastnosti pri močnem vzbujanju
V tem delu standarda IEC 62044 so določene merilne metode za izgubo moči in amplitudno prepustnost magnetnih jeder, ki tvorijo zaprta magnetna vezja, namenjena za uporabo pri močnem vzbujanju v induktorjih, dušilkah, transformatorjih in podobnih napravah z močnostno elektroniko.
Metode, podane v tem dokumentu, lahko zajemajo merjenje magnetnih lastnosti za frekvence v območju od enosmernega toka do 10 MHz in morda še celo več, za kalorimetrične in odbojne metode. Uporabnost posameznih metod za določena frekvenčna območja je odvisna od stopnje natančnosti, ki jo je treba doseči.
Metode v tem dokumentu so v osnovi najprimernejše za sinusno vzbujanje. Uporabiti je mogoče tudi druge periodične valovne oblike, vendar zadostno natančnost je mogoče doseči le, če so uporabljena merilna vezja in instrumenti zmožni obravnavati ter obdelati amplitude in faze signalov, vključene v frekvenčnem spektru, ki ustreza dani gostoti magnetnega pretoka in valovnim oblikam jakosti polja z le nekoliko manjšo natančnostjo.
OPOMBA: Za nekatere magnetno mehke kovinske materiale bo morda treba upoštevati posebna splošna načela v zvezi s pripravo primerkov in podanimi izračuni, ki so za takšne materiale običajna. Ta načela so navedena v standardu IEC 60404-8-6.
