Abstract
Zgłoszenie dotyczy urządzenia do pomiaru ultraniskich rezystancji i impedancji, mającego w szczególności zastosowanie do dokonywania metodą techniczną pomiarów przewodów wysokoprądowych np. kabli energetycznych, uzwojeń transformatorów, dławików, silników itp. Urządzenie do pomiaru ultraniskich rezystancji i impedancji, ma n toroidalnych transformatorów (T) umiejscowionych na wypełniającym ich otwory wewnętrzne i wykonanym z materiału o wysokiej konduktywności profilu (P). Profil (P) ma wewnętrzny, usytuowany osiowo przelotowy otwór, a na obu końcach pomiarowe zaciski (Z1 i Z2) oraz przyłącza (1 i 2) obiegu czynnika chłodzącego. Każdy z toroidalnych transformatorów (T) jest zasilany poprzez osobny wyłącznik (W).
