Hello all. This is a nameplate of an air core reactor. Do your have idea what is the manufacturer in full name? I tried to google but not able to find any. The name is Equip Ele?????alta Tensa? LTDA, anybody have any idea.
Keith,
That's not the name, it's the description. "Equip. electrico alta tensao" just means high voltage electrical equipment in Portuguese. From the other stuff I see on there, it looks like it maybe came from Brazil ("Bras" might be short for Brasilia), which fits with Marmites post.

ER stands for Emil Ritz, but not the same Ritz as Ritz Instrument Transformers, but Ritz Instrument Transformers used to sell/promote/have brand-labeled ER reactors and line traps in North America.
I'll save you the long history of name changes...the ER factory in Brazil is now owned by GE/Alstom Grid, so you can do to them for info.
