Query after Changing the Transformer Data (Setting View: Secondary)
If you answer the question with Yes, then DIGSI 5 will recalculate the pickup values (threshold values) in the
active secondary view. For the new secondary transformer current 5 A, the new secondary threshold value
obtained is 7.5 A (1.5 A * 5 = 7.5 A). The primary and percent values remain unchanged.
The following figure shows the newly calculated threshold value in the secondary view.
