A 3-phase transmission line is 200km long. The line has a per phase series impedance of 0.25+j0.45 Ω/km and shunt admittance of j7.2 μS/km. The line delivers 250MVA, at 0.6 lagging power factor and 120V to a 3-phase load.
a) Determine ABCD parameters of the line.
b) Find the sending end voltage, sending end current, voltage regulation and the efficiency of the line.
c) Determine the capacitance per-phase of the Y-connected capacitors to adjust the power factor of the load to unity and calculate the voltage regulation and the line efficiency in this case.
Determine the i-v characteristic of the network shown in Figure by the use of breakpoint analysis.
Installation of Meters and Verification of Connections Apart from testing and calibrating the meters they must be properly installed as per the links diagram. The points in wh

Explain and drive the expression for fixed bias and potential divider.
A 3 phase 400 volt(line to line) wye connected synchronous motor has Xs= 1 ohm per phase and a negligible armature resistance. The field current is so adjusted that the internal(in
(a) Estimate the hysteresis loss at 60 Hz for a toroidal (doughnut-shaped) core of 300-mm mean diameter and a square cross section of 50mmby 50mm. The symmetrical hysteresis loop f
When delivering rated load a 10-kW, 230-V self excited shunt generator has an armature-circuit voltage drop that is 6% of the terminal voltage and a shunt-field current equal to 4%
A universal shift register can shift in both the left-to-right and right-to-left directions, and it has parallel-load capability. Draw a circuit for such a shift register.
