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.

calculate multiplication factor of a trivector meter with line ct ratio 200/5A, line PT ratio 11000/110V and meter CT ratio 200/1A and meter pt Ratio 11000/110V.
