Why Transformer Open Circuit Test Conducted on LV side and Short Circuit on HV Side?

As we know that Transformer Open Circuit Test is conducted on LV side and that Short Circuit Test on HV side. To understand the reason behind this, we will consider a Single Phase Transformer of rating 3300  / 220 Volt, 33 kVA. Thus the voltage at the LV side of this Transformer is 220 Volt. Therefore, … Read more

Short Circuit Test of Transformer

Short Circuit Test and Open Circuit Test are two important tests which are carried out on a Transformer to determine its equivalent circuit parameters, Voltage Regulation and Efficiency.   Transformer Short Circuit Test    Short Circuit Test of Transformer is performed on HV side and the supply voltage is so adjusted that rated current flows … Read more
