Inqanaba elichanekileyo lei-transformer yangokuyimpazamo yokulinganisa (zhi ukuchaneka) dao of du, ngokubanzi 0.2, yangaphakathi 0.5, 1.0, 0.2S, 0.5S, 5P, 10P, njl. 1% -120%.Ngokuqhelekileyo, impazamo yokulinganisa kwiindawo ezi-5 zomthwalo ingaphantsi koluhlu oluchaziweyo;I-0.2, i-0.5, njl njl. ngokubanzi zilinganisa iikhoyili, kwaye impazamo yi-20 Ukuchaneka kuphezulu ngokwaneleyo kuluhlu lomthwalo we-% -120%.Ngokuqhelekileyo, iingongoma ezi-4 zomthwalo zisetyenziselwa ukulinganisa impazamo ngaphantsi koluhlu oluchaziweyo (iimpazamo zibandakanya ukuhluka komlinganiselo kunye nokwahlukana kwe-angle, kuba i-current i-vector, ngoko ubukhulu kunye ne-angle ye-angle iyafuneka), kunye ne-5P, i-10P i-transformers yangoku. ngokuqhelekileyo isetyenziselwa ukukhusela i-relay, oko kukuthi, impazamo edibeneyo ifunekayo ukuba ibe ngaphantsi kwexabiso elithile phantsi kwe-short-circuit current, i-5P ingaphantsi kwe-5%, kwaye i-10P ingaphantsi kwe-10%;ngoko ke, abaguquli bangoku banokuchaneka okwahlukileyo ngokwesicelo., Oko kukuthi, ukuchaneka kwempazamo kuluhlu lwangoku olwahlukileyo.
