DC resistance can be measured with an ohmmeter....
The reactance is a little trickier. Measure the AC resistance at 60 Hz,
remove the contribution of the DC resistance, and you'll have the
reactance, unloaded. Of course, this doesn't measure the leakage
inductance.

More at: http://home.earthlink-dot-net/~jimlux/hv/varvom.htm , which will tell
you how to measure all the transformer parameters "using only simple hand
tools".
