What Is MVA Rating in Transformers? MVA, or Mega Volt-Amps, is a unit of apparent power used to define the capacity of a transformer. Unlike kVA (kilo Volt-Amps), which is used for smaller units, MVA is commonly used for medium and large power transformers. The MVA rating of a transformer indicates the maximum load it […]
