What are Medium Voltage Transformers and where are they used?
Medium voltage transformers that have one or more windings above 1.2 k-volts. Ventilated medium voltage transformers up to 2500 kVA are covered by DOE 2016 efficiency regulation in the U.S.A. and up to 5000 kVA by NRCan 2019 efficiency regulations in Canada.
They are primarily for use in stepping down medium voltage power to a lower operating voltage for commercial, institutional or industrial applications. However, medium voltage transformers may also be used to step-up voltage.
