as well as a further c.t. operating point CT Err. F2 / CT Err. I2 (address 3013 and
3012 ), above which the angle displacement remains practically constant (see Figure
6-100), are set. The relay then approximates, with adequate accuracy, the character-
istic of the transformer. In isolated networks this angle error compensation is not nec-
essary.
