what is mva in power transformer?

MVA, or megavolt-amperes, is a unit of measurement used to express the apparent power capacity of a power transformer. It represents the product of voltage and current in a system, indicating how much power the transformer can handle without overheating. For example, a transformer rated at 100 MVA can manage 100 million volt-amperes of load. This rating is crucial for ensuring that transformers are appropriately sized for their intended applications in electrical power systems.
