Thaum lub thib ob sab ntawm lub transformer yog dheev luv luv-circuited, ib tug loj luv luv-circuit tam sim no yuav generated nyob rau hauv lub winding, thiab nws cov nqi yuav ncav cuag 20 ~ 30 npaug ntawm cov ntsuas tam sim no. Qhov teeb meem ntawm xws li ib tug loj tam sim no rau lub transformer mas muaj xws li:
(1) Nyob rau hauv qhov kev txiav txim ntawm lub luv luv-circuit tam sim no, ib tug loj electromagnetic quab yuam yuav raug generated nyob rau hauv lub winding, thiab nws cov nqi yuav ncav cuag 400 ~ 900 lub sij hawm ntawm lub ntsuas electromagnetic quab yuam, uas yuav rhuav tshem lub zog txhua yam ntawm winding;
(2) Qhov loj luv luv-circuit tam sim no yuav ua rau winding kom sov thiab ua kom kub siab, uas yuav hlawv lub winding.
