Definition of "Transformer" |
A static electric device consisting of a single winding, or two or more coupled windings, used to transfer power by electromagnetic induction between circuits at the same frequency, usually with transformed values of voltage and current. / A device composed of two or more coils, linked by magnetic lines of force, used to transfer energy from one circuit to another. Refer here for more detail, Transformer Symbols. / A static electric device consisting of a winding, or two or more magnetically coupled windings used to transfer power by electromagnetic induction between circuits at the same frequency, usually with changed values of voltage and current. / A transformer is an electrical device that transfers energy between two circuits through electromagnetic induction. A transformer may be used as a safe and efficient voltage converter to change the AC voltage at its input to a higher or lower voltage at its output. Other uses include current conversion, isolation with or without changing voltage and impedance conversion. / A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. / The telephone company's central office area in which a PSAP is located. / (1) a device that has two or more coils wound on an iron core. Transformers provide an efficient means of changing voltage and current levels, and make the bulk power transmission system practical. The transformer primary is the winding that accepts power, and the transformer secondary is the winding that delivers power. The primary to secondary voltages are related by the turns ratio of the coils. The corresponding currents are related inversely by the same ratio. |
