When we change the tap position of 10MVA transformer it suddenly tripped with Out of step indication and also with Static differential relay indication, Transformer Bucholz relay indn and Low oil level indication. Before 1 week the same problem occured by changing the tap position. but at that time only oltc bucholz relay activated. After testing the TxR Relay team & PET team cant find any solid reason. The values are ok also. So plz answer wat's the reason for this incident? anybody plz help.
