In OC test , the equipments are connected in LV side since we need to get rated voltage . if it is cinnected in HV side the value of voltage will be less and current wil be more.Hence the ordinary instruments cannot measure this value of current

Why is an open circuit test performed on the low voltage side of a single phase transformer?
You always need to apply rated voltage to the primary in open circuit test (oc test helps to find iron loss which depends on the voltage applied which remains constant)so with smaller voltage applied to the low voltage side rated voltage can be achieved in primary.Further,the ammeter ,voltmeter and wattmeter connected to the primary can be of lower rating.
Why are oc and sc tests preferred when compared to sumpners test?
OC and SC tests are used for predetermining the efficiency and % voltage regulation. It is more efficient test for a transformer than sumpner's test for 2 reasons. 1. two identical transformers are readily not available 2. two separate power supplies are required for the sumpner's test, whereas OC and SC are simple and best
Why short circuit test is done at high voltage side?
1)Short circuit test is performed at rated current. As the rated current on high voltage side is much less than low voltage side, so the rated high voltage side current is easily achieved compared to low voltage side. 2)Also because we cannot short circuit high voltage side, as, if we short circuit high voltage side, voltage of high voltage side essentially falls to zero and since VI=constant, so the high voltage side current will be very high and will burn the winding.
Why should you use sumpners test on transformer?
sumpners test is performed to find core losses and copper losses.here we can find effieciency and regulation by actually simulating the loading conditions.hence the results obtained by this method are more accurate than oc and sc test where loading conditions are absent.we can perform heat run test which is an advantage of sumpners test as both losses occur simultaneously

What are the advantages of OC and SC test compared to load test?
> Predetermination of regulation. > Predetermination of efficiency. > Less power loss.
