Default Testing a 70.7v transformer

I decided to try testing a cheap 70.7v line transformer on the impedance analyzer at work. The graph represents the primary impedance with a 10 ohm resistor load on the secondary. The X axis is frequency and the Y axis is impedance. The inductance was not very high, around 5-6 henry. Anyhow heres the results.

If I've done my sums correctly, the leakage inductance is around 22mH. I'd say this impedance analyser might be quite useful for comparing output transformers.
