The I> pickup level setting is a per unit value related to the current transformer ratio.
Example:
300/1 ratio and pickup level 2.5 corresponds to a primary current level of
300 × 2.5 A = 750 A
The I
0
> pickup settings in Amperes are based on a current transformer ratio of 300/1. In the case a different
ratio is used the levels are scaled proportionally.
Example:
150/1 ratio and pickup level of 2 corresponds to a primary current setting of
150/300 × 2 A = 1 A
