Answer / sanjit bal

DC will be blocked. Capacitor gives easy path to AC.

Answer / ashok

No current will flow, as capacitor behaves as a open circuit
to dc supply.

Answer / s.bharathi.1991

if the d.c passes through the capacitor ,it would offers
infinite resistance to ac because the capacitive reactance
for d.c is given by

xc=1/(2*3.14*f*C)


where,
c-capacitance
f-frequency

since for d.c the frequency is 0,xc=infinity.hence no
current flows through capacitor

Answer / gurubhai

IT WILL GET DAMAGE DUE TO CURRENT SURGE.

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.
