The reason I asked is the term has become more than confusing. A line voltage correction unit is vastly different than something that screams to itself "Incoming!" and disconnects the rig from shore power.
Does Hughes for instance provide specifications for transient voltage line disturbance protection? CORRECTION of line harmonic distortion?
HOW and WHEN does a unit "protect" against out of specification limit voltage. How is "improper voltage" defined?
Improper Connection Protection is yet another category.
1. Improper connection protection
2. Improper voltage protection (?) or correction (?) Protection can mean disconnection of service.
3. Transient voltage protection. No standards are realized.
4. Harmonic distortion correction or protection (disconnect)?
SURGE PROTECTOR is an Alice In Wonderland grade buzzword. The dozen or so fried "Autoformers" I have autopsied could have been prevented with an addition of an "Out Of Range" auto disconnect of shore power. I could not believe a 600+ volt reading on my min-max recorder when a distribution transformer blew up.
I guess I am cursed by being an engineer and believing in plain English standards and specifications.
