Liquefaction System for 121kv

2017-5-30The value for the system MVA is generally specified by the value given by the utility system. For a generator or transformer, a line or cable, the MVA is equal to the equipment-rated MVA divided by its own impedance and by the square of the line-to-line voltage divided by the impedance per phase, respectively.
