F1 (address 3011) of the c.t. with its associated current CT Err. I1 (address 3010)
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.
