WebThe third transformer is a hot standby so that it takes over the load of 1 of the two transformers under conditions of outage or maintenance scheduling. Here is a quick recap of what you have learned thus far. The transformer losses consist of no load, that is iron loss, load that is copper loss, and auxiliary loss. WebCopper Loss The ohmic resistance of the transformer windings creates copper loss. The copper loss for the primary winding is I12R1 and for the secondary winding is I22R2. Where, I1 and I2 are current in primary and secondary winding respectively, R1 and R2 are the resistances of primary and secondary winding respectively.
