Kev tiv thaiv xaiv rau lub zog transformers

① Transformer thawj tam sim no=S / (1.732 * 10), theem nrab tam sim no=S / (1.732 * 0.4).

② Transformer thawj fuse xaiv=1.5 mus rau 2 npaug ntawm transformer tus thawj rated tam sim no (rau transformers saum 100KVA).

③ Transformer theem nrab hloov xaiv=transformer theem nrab ntsuas tam sim no.

④ Transformers ntawm 800KVA thiab saum toj no yuav tsum, ntxiv rau kev txhim kho cov roj relays thiab tiv thaiv circuits, muaj qhov tsim nyog overcurrent thiab instantaneous overcurrent tiv thaiv nyob rau hauv lub system Circuit Court; teeb tsa cov nqi thiab kev txheeb xyuas raws sijhawm.
