SPECIFICATION FOR CURRENT LIMITING REACTOR AKA SERIES REACTOR

[Redskinsdb21]

DOES ANYONES HAVE A CLUE WHERE I COULD LOCATE A SAMPLE SPECIFICATION FOR A CURRENT LIMIINT REACTOR/SERIES REACTOR.

The "specification" is usually what the end user requires in terms of performance: how much current to carry, how much loss (iron and copper) is acceptable, applied voltage, method of protection, overall power quality, cycle of use (which may be continuous, but may not), environment of application, etc.

Note that above a certain rating, almost all (high power) reactors are custom products ... or at least semi-custom. That means the manufacture is done with present raw material prices - which are going to be higher than in recent years as the components of a reactor tend to be copper, steel, and insulating media.

Also - just because the cost seems to be a "fortune" to the OP does not mean it's a fortune to others. Quantitative description is (almost) always better than qualitative.

I probably should have worded my question a little differently, but I am more specifically looking for a sample specification for purchasing a reactor.

Reach out to a manufacturer. They will likely have a canned spec.

I'd contact Trench. They should be able to help you out.

Although reactors are custom made, it is fairly straight forward to specific them by looking through the applicable IEEE standard and filling in the blanks. Here are the technical portions from a fairly old specification. I second the advice to talk with Trench, as they have been helpful to me in the past.

Be aware that reactors cause large magnetic fields that can damage nearby rebar or steel support structures. Design of the foundation and supports can harder than purchasing the reactors themselves.

5.08 REACTORS
5.08.1 NAMEPLATE REQUIREMENTS
The nameplate shall be stainless steel or anodized aluminum permanently imprinted, scribed and/or embossed with all the information recommended per IEEE Std. C57.16-1996, Section 12.1.1
