Query after Changing the Transformer Data (Setting View: Secondary)
If you answer the question with Yes, then DIGSI 5 will recalculate the filtering time (threshold values) in the
active secondary view. For the new secondary transformer current 5 A, the new secondary threshold value
obtained is 1.50 A (0.300 A x· 5 A = 1.50 A ). The primary and percent values remain unchanged.
The following figure shows the newly calculated threshold value in the secondary view.
