Electrical Transformers Symbols
Single Line Representation
The electrical transformer is a component consisting of two or more coils coupled by magnetic induction. It is used to transfer electrical energy, and to increase or decrease the tension in an AC circuit, keeping the frequency.
The autotransformer has only one winding.
Two windings are shown
|Single-phase transformer with separate windings||Current transformer with two cores with a secondary winding on each core|
|Current transformer with three conductors||Current transformer with two secondary windings on a core|
|Dual current transformer with the same core||Transformer power outlet|
|Single-phase transformer with a winding bypass intermediate||Inductance|
|Three-phase transformer with regulation of induction||Transformer with three windings|
|Autotransformer||Single-phase transformer coupling variable|
|Single phase autotransformer||Single phase autotransformer with voltage adjustable|
|Three phase auto transformer with star connections||Three-phase voltage transformer|
|Three-phase transformer with star / star connection||Three-phase transformer with star / delta connection|
|Three-phase transformer with connection star / delta||Three-phase transformer with connection star / zig zag and neutral output|
