in three phase 11kv transformer (11kv/433v)
input( R,Y,B) output (X,Y,Z,N) the connection as follows
1 phase R -open
2phase y connected to both R and y of input]
3phase B- B
what is the output voltage X to N ,Y to N , Z to N


Answer Posted / pradyumna chandra panda

phase voltage ie. voltage b/w x-n. y-n and z-n is 250 volt each but line voltage b/w x to y = 0 volt y to z= 433 volt and z to x = 433 volt
