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

by

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

Open Circuit Test of Transformer

by

Open Circuit Test and Short Circuit Tests are two important tests which are carried out on a Transformer to determine its equivalent circuit parameters, Voltage Regulation and Efficiency. Though theses parameters can also be found using the physical dimension of Core and Winding detail but using Open Circuit and Short Circuit Tests are quite easy … Read more
