Transformers - Mfrs & Suppliers
A transformer is a static electrical device that transfers energy between its winding circuits. Transformers range in size from thumbnail-sized units hidden inside stage microphones to units weighing hundreds of tons interconnecting parts of the power grid. A wide range of transformer designs are used in electronic and electric power applications. Transformers are essential for the transmission, distribution and utilization of electrical energy. Transformers are used to increase voltage before transmitting electrical energy over long distances through wires. Transformers are also used extensively in electronic products. Signal and audio transformers are used to match devices such as microphones and record players. Audio transformers allow telephone circuits to carry on a two-way conversation over a single pair of wires.
