If want to conduct OC test on HV side we need more turns of auto-transformer, as an engineers we should have to decrease the cost required for the test, so normally OC test is conducted on LV side since we need less turns of auto-transformer

Voltage injection in LV side is convenient, The cable attached to LV side also need insulation suitable to LV voltage rating. If LV ia in the range of 440V and HV is of the range of 11KV, we may inject voltage in steps also through variac of 440V , Which is not possible if inject voltage in HV side.

Change in Frequency
Why do we maintain 50hz frequency? What happens when we change this frequency to any other value?

AC Electrical Network need to have a syncron phase for them to work. Any differences in term of frequency will shift out this syncronisation and lead the whole system to fail.
