Q1. A rectangular surge of 2us duration and magnitude of 100Kv travels along a line of surge impedance 500 ohms. The latter is connected to another line of equal impedance through an inductor of 500uH. Calculate the maximum value of surge transmitted to the second line.
Q2. The effective inductance and capacitance of a faulted system as viewed from the contacts of a breaker are 2.5 mH and 600 pF respectively determined the restricting voltage across the barker contacts when a flute current of 150A is chopped.
