Miscellaneous on Transformer

* 3-Фtransformer’s each phase should have balanced load. Otherwise insulation will break by overheat and Tx will be damaged. In Bangladesh 80 % cases Tx are being damaged due to unbalance load.

* If core is cut by Miter shape that increases efficiency. This core helps full of flux cuts, so that its efficiency is higher.

* HT side keeps in outside of the winding cause most cases HT side winding need to repair.

* In REB (Rural Electrification Board) use 1-phase Tx, that can be identified by 1- bushing in HT side, that has 6350 volts. Cause in rural areas maximum loads are 1-phase. That case neutral is comes from earthling of a side of Tx.

* Distribution Transformers consumer side end (LT) is made Y connection so the neutral can be used. HT side connection is ∆.

* For minimizing of EDDY current loss cores are made of peace of sheets.
