Electrical Transformer Diagram. The transformer works on basic principles of electromagnetic induction and mutual induction. And primary winding a1a2 corresponds to secondary winding a1a2.
Note how much simpler and cleaner the single line diagram is compared to the schematic diagram of the same power system. Such transformer has two winding ie. 120 x 240 secondary.
According to the wiring diagram on the nameplate.
Low voltage electrical wiring lighting systems inspection repair guide. T 2 53515 3s acme electric general purpose transformers galco electronics. The power gained from the transmission lines is at a high voltage which is decreased by step down transformers so that a consumer can get electrical power at a normal voltage level. Below is a diagram of a typical power transformer.
