Abstract

For å karakterisere en elektrisk komponent (1), nemlig en middels eller høyspenningstransformator, elektrisk motor eller generator, utføres en totrinns prosedyre. I et første trinn blir et sett av terminale konfigurasjoner påført terminalene (p1,...pn) av komponenten (1) for å oppnå data som beskriver den lineære elektriske respons av komponenten 1 på ethvert mønster av spenninger uk eller strømmer ik påført terminalene (p1,...pn). Typisk blir slike data for eksempel uttrykt i form av en admittansmatrise Y eller impedansmatrise Z, eller med fordel ved settet av strøm og spenningsvektorer (ik, uk). Brukes disse data kan den lineære elektriske respons av komponenten 1 under en testterminalkonfigurasjon nå beregnes i et andre trinn. Denne prosedyren tillater å bestemme responsen under enhver ønsket testterminalkonfigurasjon uten behovet for å utføre målingen under testterminalkonfigurasjonen.
