Calculating Transformer Rating

Load rating for transformers are usually given as VA or kVA.  These power ratings are obtained by multiplying the load current by the supply voltage, this gives the volt-ampere rating, where 1000VA=1 kVA. This is referred to as the power rating of the transformer.  The power which the transformer can deliver to a given load also depends on power factor, which is defined as the ratio of real power to apparent power - the absorbed power divided by the volt-ampere product.   For a resistive load the power factor is unity and the transformer will be able to supply a load power equal to its VA rating. The majority of loads are resistive loads having a small reactive or inductive or a capacitive component which should be taken into account.  When a power factor value is unknown, for simple calculation purposes it usually assumes a value of 0.8.

Transformer Rating of Secondary Voltage

Secondary rating on a transformer is the secondary voltage, which could be more than one on a transformer.  The secondary transformer rating also has a maximum current or power which it can deliver to a load.  The total VA rating of all the windings will normally equal the VA rating specified as the total load rating of the transformer.  The secondary voltages for each set of secondary windings must be specified, along with the VA in each case.  The only exception to this is when there is only one secondary winding; in this case it will have a rating equal to the total load rating for the transformer.

K-Factor Transformer Rating

A K-Factor rating on a transformer is its ability to supply harmonic content in its load current while operating within it temperature limits. In dry type transformers a K-Factor calculation is made to determine the amount of the harmonic content present in a power system.   K-rated transformers are sized to handle 100% of it 60 Hz load (as an example), plus the non-linear load specified.  The neutral of the K-rated transformer is sized at 300% of the current rating of the phase connections. Common K-factor ratings are K-1, K-4, K-9, K-13, K-20, K30 and K40. Transformers can also be designed with other K-factor ratings.  See also K-Factor Transformers.
