I am trying to model a current transformer in SPICE. It's one of those with a hole through the middle where a current-carrying wire goes to make the primary.
The secondary measures as 6H in series with 100Ω.
The usual method of measuring leakage inductance doesn't seem too successful: with a shorted turn where the primary goes, the secondary inductance only reduces to 5H.
The CT in question is rated 100A:50mA.
Obviously, I could just model it as L1=1.5uH, L2=6H, K=1, but I'm pretty sure that K≠1
