132 Kilo Volt Amps (kVA) is the amount of theoretical power being used by the transformer. The transformer takes high voltage from transmission lines and converts it to lower usable voltages. the power of 132 kVA comes from the product of current (I) and voltage (V) going into or coming out of the transformer. The gridstation as a whole takes in a few large power transmission lines, transforms their voltage, and distributes electricity to consumers.
