Generally the PT or CVT are used to measure voltage.
The secondary of the PT will be 110V which will be connected for the voltage measurement. For high voltage applications like 132 or 230 or 400kV. Designing the PT for 132 to 110V will be very bulky and practically leads to very big size.
Hence for high voltage applications we use CVT. The CVT is constructed using serious of capacitors. Consider we are connecting 10 capacitors of equal rating in series. Hence the voltage along the capacitors are equal we will take output of one capacitors are connect it to a PT and secondary of PT 110V will be used for measurement.
