Example 6: Calculate the capacitance and charging current of a single core cable used on a 3-phase, 66 kV system. The cable is 1 km long having a core diameter of 10 cm and an impregnated paper insulation of thickness 7 cm. The relative permittivity of the insulation may be taken as 4 and the supply at 50 Hz

The diameter of an ACSR conductor is 1.162 inches. The steel core has 7 strands of diameter 0.1291 inches each. If Aluminum strands have the same diameter as that of a steel strand, the number of Aluminum strands is: O A. None of choices are correct O B. 36 O C. 74 O D. 54 O E. 45

The diesel power station cannot be located at any place (T or F) The d.c resistance of various types of conductors at specified temperature (T) is found by...... The self-GMD of a conductor depends upon the ...... ...... and ..................of the conductor The voltage drop is increased if the length of transmission line is increased (T or F) The skin effect depends upon the.............. ........ and ********* , and..... …........

A 500 MVA synchronous machine has H, = 5.6 MJ/MVA and a 1200 MVA machine has H₂ = 2.0 MJ/MVA. The two machines operate in parallel in a power station. What is the equivalent. H constant for the two, relative to a 100 MVA base?
