GB14711 wuxuu qeexayaa in masaafada creepage iyo nadiifinta korantada ee matoorrada korantada yar ay tixraacaan: 1) Inta u dhaxaysa kirishbooyada dhex mara dusha walxaha dahaarka iyo booska bannaan.2) Fogaanta u dhaxaysa qaybaha nool ee daboolan ee voltado kala duwan ama inta u dhaxaysa polarities kala duwan.3Fogaanta u dhaxaysa qaybaha nool ee bannaanka ah (oo ay ku jiraan fiilooyinka magnetka) iyo qaybaha (ama laga yaabo) inay dhulka yihiin marka matoorku shaqaynayo.Fogaanta creepage iyo nadiifinta korantada way kala duwan yihiin iyadoo loo eegayo qiimaha danabka waana inay u hoggaansamaan qodobada shaxda1.Matoorada leh danab lagu qiimeeyay1000V iyo wixii ka sareeya, faraqyada korantada ee u dhexeeya qaybo kala duwan oo nool oo bannaan ama qaybo ka mid ah polarity kala duwan ee sanduuqa isgoyska iyo inta u dhaxaysa qaybaha noolaha (oo ay ku jiraan fiilooyinka korantada) iyo biraha aan hadda qaadin ama biraha la dhaqaajin karo iyo masaafada gurguurta waa inaysan noqon in ka yar shuruudaha shaxda 2.
