Saturable Inductor
Saturable Inductor
(OP)
Has anyone heard of using a saturable inductor in grounding a power distribution transformer? Better yet, anyone know what a saturable inductor is?
The application is serving a very sensitive laboratory experiment. One of the scientist recommended using a saturable inductor at the power distribution transformer, which is 2MVA and shielded,dry type to help mitigate "noise" issues.
Refernce to technical papers or products would be helpful.
Thanks.

RE: Saturable Inductor
In this technology, a DC magnetizing voltage is applied to the center leg of a 3-legged core, the other two legs carry the AC reactor windings. Varying the DC voltage varys the amount of flux saturation of the cores, thereby changing the reactance of the AC windings, and therefore the current in the AC circuit.
The usual control voltage was something like 0...75VDC, usually, in fact, the output of a magnetic amplifier system, which was the regulator type widely used at that time.
Probably findable on Google...

I'm not sure how that would help in terms of "noise" however. It's mostly used to limit damage to equipment from ground faults, just like a Neutral Grounding Resistor system.
