Short Circuit Test of Transformer Performed on HV Side
This can be illustrated by Considering a 3300/220 V , 33 KVA Single Phase Transformer.
Short - Circuit Test on the h.v. side, The instrument ranges are 165 V(2 to 12 % of Rated Voltage of 3300 V), 10 A(Rated Current) and 10 A,165 V, Which are well within the range of the ordinary instruments.
On the other hand, instrument ranges for a Short Circuit Test on l.v. Side are 11 V ,150 A, and 150 A,11 V . The instruments of Such ranges and Auto Transformer capable of handling 150 A , may not be Readily available and the same time , the results may not be so accurate. It is the reason Short-Circuit tests are conducted on h.v. Side.
