Power consumption of Transformer
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)

Isolating transformer's turns ratio 'a' is not necessarily always a =1
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)

Ideal transformer equations
I suggest we specify that equatations are time-variant and are derived for the AC. AXO NOV (talk) ⚑ 20:37, 23 July 2022 (UTC)

Confusing label on Laminated steel core photo
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)


 * 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)
