A CCVT is connected to its rated primary source voltage of 138/√3 kV. The value of the capacitor from the high-voltage terminal to the tap point is 0.005µF. The tap point voltage is 4 kV. What is the value of the capacitor connected between the tap point and the ground terminal? What is the value of the tuning inductance? If the power system frequency changes between 58 and 62 Hz (assuming the normal frequency to be 60 Hz), calculate and plot the ratio correction factor of this CCVT as a function of the power system frequency. Assume the burden connected to the secondary of the transformer to be 300 resistive, and assume the transformer to be ideal.
note/ the ratio correction factor is R = E2/E1 , where E2 is the voltage across the burden ,and E1 is the voltage of the source.
