The iron core of metering CT is smaller compared to that of
protection scheme, for accuracy. Its core reaches magnetic
saturation , if the current exceeds the rated value by a
certain value. After the saturation is reached, the
secondary current wii not incease with the primary
current .

For a 6.6kV Motor it is recommended to do megger test with 500 V d.c and not more than 5kV d.c but the Hi voltage withstand test should be performed by 12kV AC. Why the dc voltage test should be limited but AC voltage withstand test could be with such a high voltage?
