Abstract
Inventia are ca obiect o metoda si un dispozitiv de masurare a marimilor electrice la cuptoare cu arc electric. Conform metodei, valorile tensiunilor pe faza masurate sînt corectate cu valorile tensiunilor induse, cuplajele inductive estimîndu-se din defazajul curentului masurat si tensiunii astfel estimate. Dispozitivul este realizat cu trei traductoare de curent de la care semnalul este aplicat unor blocuri de detectare a defazajului, sumatoare, integratoare si multiplicatoare prin trei traductoare inductive pentru masurarea derivatelor curentilor.
