FOR 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?
we done magnetic balance test for 33KV /440V transformer
in our company , but the ratio out is confusing us
Voltage applied in RY = 440 , at RB = 320 and YB = 60
RY 440 = ( RB + YB ) 380 only
Please let me know what type of problem is it.
if we going for high voltage usages what are the
considering factors, why those factors are effected....
please give me an answer related motor factors like
wnidnig, frame, temp etc
2. Modify your design in question 1.a so that the circuit
works according to the following function table
X Y F
0 0 Clear
0 1 No Change
1 0 Parallel Loading
1 1 Count
3. Design a circuit that detects the pattern 010 in a serial
input X considering:
3.a Overlapping
3.b No overlapping
