Hello all,(adsbygoogle = window.adsbygoogle || []).push({});

I am new to the forum and hope my question is appropriate for this section.

My question is about per-unit notation and calculations. Basically I've been given the resistance, reactance at the primary and secondary windings of a transformer, core losses and inductance, etc. The transformer rating (does not specifically say it is the base rating) is 100 kVA and the base voltage is 1 kV. Among other things I have to calculate the per unit values for the resistance, reactance, losses, etc, but what I cannot understand is how you can calculate the base rating. Is it just the same as the regular transformer rating?

Any answers will be much appreciated. Thanks!
