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.
please answer the following question:

5. Two long boundary walls run parallel to each other
at a center to center distance of 1 meter apart. The width
and height of the first wall are 0.30 m and 2.5m
respectively. While those of the second are respectively
0.18m and 3.5m. Plot the distribution of vertical stress
intensity due to walls on a horizontal plane, 1m below
ground level. The walls have negligible depth of foundation
