if HT side voltage is high current is low . and LT side
voltage is low current is high please explian.
Answer Posted / bhavesh chauhan
Voltage and Current are inversely proportional to each other in Transformers.. As the value of voltage increases current decreases, and as the value of voltage decreases the current value increases.... I Will make you count..
Practically i work in a 220/66/11 kv power station.
I have a 100 MVA Transformer which is a Step Down X'mer. The H.V Side of the X'mer gets 220KV input and L.V of the X'mer gives 66KV output...Now to calculate ............
The Current for H.V Side according to P=VI
we have P=100 MVA
V=220 KV
I=?
I= 100 10^6 /1.732 X 220 X 10^3 = 262.24 Amps
Similarly for L.V
I= 100 10^6 /1.732 X 66 X 10^3 = 874.79 Amps
These are the Actual H.V and L.V Current reading of a working transformer... Which proves that when Voltage decreases current increases..........Thank you
