Transformer) under load conditions •limits the short circuit currents and resulting forces •specified by customer (can be per ieee std) •can be expressed in % of rated impedance. Voltage drop is 600 volts, then the percentage voltage drop is 10% and, thus the transformer percentage impedance is 10%.so we can say,the percentage impedance is the percentage.
