[TCML] The Dreadful Task of Ballasting (longish)

[BunnyKiller]

Hey Harvey...

Do what? Why not just hook the inductor up to a variac and amp meter and 
start at 0 volts and increase the voltage in X number of volts and read 
the amps pulled on the meter at each succesive reading untill saturation 
occurs ( basically a severe increase in amps drawn) and then input the 
curve of amps drawn and voltage applied to get the inductance/ohms of 
the inductor?
Thats pretty much how I determined how to set my inductor to 60 amps at 
280VAC. I set the gap to a certian point and brought the voltage up to 
280VAC and took a look at the meter. If it was too low, I closed the gap 
untill I got the reading I needed. sometimes the try it till it works 
does the job...

Estimate the inductor as a total value of inductive reactance; note the drop in amperage to the bulb,(as a pure resistance) and apply trig to the problem. The new value of conduction should be based on the ohmic value of the hypotenuse with y as X(L) and bulb resistance as the x coordinant.
