What does Code C ANSI Standard CT Accuracy Class indicates

While referring to ANSI Standard CT Accuracy Classes, the Code C implies that the transformer ratio can be calculated. The code C classification covers most bushing CTs that have uniformly distributed windings and any other transformers whose core leakage flux has a negligible effect on the ratio, within the defined limits.
