Line reactor nameplate ratings are typically given in terms of rated inductance and let thru current at a given available fault current at the line side of the reactor at a particular voltage (in my example it's 67uH with a let thru of 9416A with 65kA @ 480VAC applied to the line side of the air-core reactor).

I'm running a calculation where it's important to know both the x and the r of the reactor. I can calculate the x based on the 67uH inductance. However, in order to calculate r, I believe I would need to know the x/r ratio of the 65kA at the line side of the reactor so I can "back calculate" from the 9416A let thru rating. I don't have a test report available.

Does anyone know the typical test x/r ratios applied to a line reactor in order to give its nameplate rating (i.e. the x/r ratio of the 65kA on the nameplate)?
