Power consumption of Transformer[edit]

How can we calculate the power consumption of transformer itself? — Preceding unsigned comment added by 114.29.229.115 (talk) 04:36, 17 May 2020 (UTC)[reply]

Isolating transformer's turns ratio 'a' is not necessarily always a =1[edit]

Referring to Ideal transformer equations, it is at best misleading to show that 'and for an isolation transformer a = 1'; saying so is true only as far as it goes. It is like a stopped clock that is right twice a day. An isolation transformer is a two-winding transformer that often has a turns ratio a = 1 and is not an autotransformer. But an isolation transformer can also be step-up type or step-down type. Cblambert (talk) 20:08, 29 January 2022 (UTC)[reply]

Ideal transformer equations[edit]

I suggest we specify that equatations are time-variant and are derived for the AC. AXONOV (talk) ⚑ 20:37, 23 July 2022 (UTC)[reply]

Confusing label on Laminated steel core photo[edit]

In the "Laminated steel core" section of the Wikipedia Transformer page the photograph reads "Laminated core transformer showing edge of laminations at top of photo". The picture is of a Shell type transformer. This is a confusion point as some will take it that it is a core type when it is not. I suggest changing either the photo out or changing the description to either. A shell core type transformer or in the description to "Laminated Shell transformer showing edge of laminations at top of photo". 69.201.21.27 (talk) 16:34, 3 October 2022 (UTC)[reply]

Core has a dual meaning. It is type of transformer construction. The magnetic material is also called the core whether the transformer is shell type or core type. Constant314 (talk) 19:58, 3 October 2022 (UTC)[reply]
