Hence, the transformer constitutes an impedance-tocurrent flow from source to load. The higher that impedance, the more voltage drop will occur for a given load current. If a downstream fault occurs, its effect on the circuit will be lessened to the extent that transformer impedance increases.

Calculations for determining short circuit capacity and transformer sizing is given here. ... A 30 kVA transformer rating is too small as the motor voltage drop will exceed 10%. A 45 kVA transformer with a 2.4% impedance and an output of 54.1 amps at 480 volts would have a short circuit capacity of 2034 amps.

1. 2. 3. 4. Measure Mains Impedance at Source Identify Source Voltage Identify Load Voltage Normalize Impedance Ohms Volts Volts Source Impedance x Load Voltage / Source Voltage 0.150 @ 480 VAC 480 VAC 208 VAC 0.150 x 208 / 480 = 0.028 @ 208 VAC Transformer Impedance Transformer impedance is usually listed on the nameplate.

If 125A drops 23V, then 14A will drop 14A/125A*23V or 2.6V. This value 2.6V is less then recommended drive input line impedance voltage drop of 4.6V. The conclusion is that 5% impedance 100kVA transformer does not meet the requirement of 1% impedance for 10HP drive.

Impedance; Transformer Impedance and Voltage Regulation are closely related: a measure of the transformer voltage drop when supplying full load current.

The percentage impedance of a transformer is the volt drop on full load due to the winding resistance and leakage reactance expressed as a percentage of the rated voltage.

In many cases, the transformer supplies several pieces of equipment and in those cases, its kVA rating may be several times larger than any individual load, rendering the transformer impedance ineffective at reducing harmonic current distortion.
