① Cov qauv ntsuas roj - ntsuas kev ua tau zoo xws li tiv taus hluav taws xob thiab impurities yuav tsum tau sim txhua peb xyoos. Lub sijhawm no tuaj yeem ua luv luv rau cov khoom siv hluav taws xob ua haujlwm puv lossis dhau sijhawm ntev.
② Siab thiab tsis tshua muaj hluav taws xob rwb thaiv tsev yuav tsum tsis txhob tsawg dua 70% (10MΩ) ntawm tus nqi qub Hoobkas. Qhov sib txawv ntawm peb -theem nruab nrab DC tsis kam ntawm cov windings ntawm tib qhov kub yuav tsum tsis pub tshaj 2%, thiab yuav tsum tsis pub tshaj 2% piv rau qhov ntsuas dhau los.
③ Transformer ua hauj lwm grounding kuj yuav tsum tau ntsuas txhua ob xyoos.
④ Lub voj voog hluav taws xob tu thiab tshuaj xyuas yuav tsum tau txiav txim siab raws li qhov chaw nyob ib puag ncig thiab kev thauj khoom, feem ntau txhua txhua rau lub hlis mus rau ib xyoos.
