Higher order harmonics during inrush

Higher order harmonics during inrush

Higher order harmonics during inrush

(OP)
Is it typical for higher harmonics to increase well after transformer energization? The attached file show 3rd and 5th harmonics actually peak after about 2 seconds. This is first time our transient recorder has capture this long of file, so I curious as to whether this is typical.

The bank is 500 MVA 230/115 kV autotransformer. The graph has both the bank neutral and high side phases. The phase harmonics are B phase as it was the largest in magnitude.
