what purpose of the percentage impendance in transformer..

The Transformer impedance plays a major role in power system.

The Transformer impedance will reduce the fault current. If there is high impedance transformer placed between the circuit. The transformer will acts as isolation to fault current.

In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
