Measuring CT is of accuracy class 0.1 to 1.0. For protection
class PS.Not accurate but capable measuring currents 5 -20
times the rated, without getting saturated.

Why we transmit the power at the voltage in the multiple of 11 or 1.1 like 11kv, 22kv, 66kv, 132kv...... some one told me that it is due to fomr factor 1.1 of sine wave. its fine but while transforming we can choose any voltage, so why only multiple of 1.1 there also.......? plz tell me.
