Glossary Of Terms


A passive electric device consisting of multiple coupled windings, used to transfer power by electromagnetic induction between circuits at the same frequency. A transformer can have the same input (primary) and output (secondary) voltage, in which case it is called an isolation transformer, or the output voltage can be higher than the input voltage (step-up transformer) or lower than the input voltage (step-down transformer.) Since the power supplied to the input must equal the power supplied at the output, current values will vary from primary to secondary in an inverse manner to the voltage. For instance, if a transformer is rated at 480 volts and 100 amps on the primary, at a 240 volt secondary the available current will be 200 amps.
