what does vector group Dyn11 tell us? also tell me how will u differentiate between phase lead and phase lag thru this vector group
1609FOR 16/20 MVA 132/33 KV ONAN/ONAF TYPE TRANSFORMER IT IS DESIGNED FOR 16 MVA WITH ONAN CONDITION.IT BECOMES 20 MVA UNDER ONAF CONDITION.LOAD LOSS IS GUARANTEED FOR 65KW AT 20 MVA AND % IMPEDANCE 13.75. PLEASE TELL US AT WHAT LOAD LOSS AND % IMPEDANCE IT SHOULD BE DESIGNED FOR 16 MVA AND WHAT WILL BE ITS EFFICIENCY AT 20 MVA?

2 4539i have done my b.tech in 2009 .still hunting for a job...wat shud i answer if intervevwr asks..(what u have done 1yr)
TATA,
1 29451. What will happen if the armature rheostat is not in maximum position while starting the motor? 2. What will happen if the armature resistance is in minimum position and the eld resistance is in maximum position while starting the motor? 3. How do you reverse the direction of rotation of a DC motor? 4. If the armature connection and the eld connection both are reversed, does the direction of rotation of the motor reverse?
