An RC series circuit with R = 150 Ω and C = 2 μF is excited by a DC source of 15 V by closing the switch at t = 0 with an initially uncharged capacitor. The initial and final voltages across the capacitor respectively are

Murray loop test is performed on a faulty cable 300 m long. At balance, the resistance connected to the faulty core was set at 15 Ω and the resistance of the resistor connected to the sound core was 45 Ω. Calculate the distance of the fault point from the test end.

The necessary equation to be solved during the load flow analysis using Fast-Decoupled methid is given below:

where B' and B'' are formed using the imaginary part of the bus admittance matrix Ybus, n is the total number of buses in the system, m is the number of voltage regulated buses. The size of matrix B' is

∆P/|Vi|= -B' ∆δ

∆Q/|Vi| = -B'' ∆|Vi|
