5�9�- C/K FACTOR
The C/K factor is adjusted according to the reactive current provided by the smallest stage, measured
in the secondary of the current transformer (CT). The adjustment value of this factor therefore depends
on the power of the smallest stage, the ratio of the CTs and the network voltage.
provide the values to which the C/K should be adjusted for a 400 V AC network
between phases, various transformer ratios and powers of the smallest stage.
