Pad mounted transformer for electrical distribution. A transformer is an electrical device that uses electromagnetic induction to pass an alternating current (AC) signal from one electric circuit to another, often changing (or "transforming") the voltage and electric current. Transformers do not pass direct current (DC), and can be used to take ...

Transformers work using the principal of electromagnetic induction, something the British scientist Michael Faraday first realised in 1831. He noticed that when a magnet moved through a coil of copper wires, a current flowed through those wires. It''s this same principal that enables spinning turbines to generate electricity today.
Step-up transformers. Reversing the situation, we can make a step-up transformer that boosts a low voltage into a high one: This time, we have more turns on the secondary coil than the primary. It''s still true that: Secondary voltage ÷ Primary voltage = Number of turns in secondary ÷ Number of turns in primary. and.
