The first question is "why?"
If there is some specific power quality issue you need to address, then seek out appropriate solutions.
I am in Northern Manitoba right now. But that could change. I lived in The Northwest Territories, Nothern Alberta and Northern Saskatchewan.
Spent at least part of each of 27 years, and sometimes up to 30 months continuous near the Nunavit / NWT / SK / MB border confluence. Power there is not part of the grid; a sole line, without interconnection to a power grid that can be brought into use during outages; if it's down across it's 140 mile length, it's down everywhere until it's fixed. Large industrial users on the line, three Native reserves, and small users. Mostly bush, and a single tree across the line during a storm can shut it down.
SaskPower was very good at keeping it up, with quick dispatch of helicopter crews, but partial shorts (trees in the wind, not quite shorting the line) were common. In general, voltage could fall to the 90's and surges when the industrial users came on or off the grid were common. The knife switch at one facility threw an arc three feet long when you moved it towards connection or remained connected via the arc for most of the rotation during shutdown. A nice steady 60 Hz, but then again, sometimes you were on the generator so that goes variable too.
All in all, very bad power for electronic power supplies. So what was the effect?
A computer with CRT display, NAD receiver (vintage) ... the computer I sold after seven years, had 13,500 hours logged on it. Working perfectly. The NAD I still own, works fine. Our office was fully computerized, even back in the late 1980's (yes, I worked on a Compaq Portable, 5" orange character screen, MS-DOS because Windows 3.1, which was the first version that worked, was five years away). They all worked fine.
Fast forward to today and there are a dozen iMacs, a MacOS Server machine, the usual office gear, a full pubic-use 7.1 AV system, electronics through the rooftop, and there is now 3-phase power, same grid, to the site. Everything works just fine, lasts as long, maybe even longer, than expected, no noises, no buzzes.
In fact using a Mac Mini, Audio-gd DAC, and IEMs, it was quieter than the power in my home now, and that is good power.
Power with the interconnected grid (back in the city) is worse, actually, despite that northern grid pushing all the buttons claimed for a power conditioner or regeneration device.
So, short answer, be careful what you buy, you may need nothing, or you may need who-knows-how-much help there. Go across the street and the requirements could change. I would not buy anything without a dealer loan first. Spending big bucks on something you don't need or doesn't work as intended to me is poor economy.
If you're looking to do this kind of thing on the cheap, then hope you don't need much, or any, help, because like everything that is designed for electrical vs electronics use, it's expensive. People get lulled into thinking it's commodity use stuff and because your outlets probably cost the contractor $0.79 a pop that it's all cheap in massive volume, but the second you buy something that is *not* used in massive volume, it's just plain expensive.
It's an industry built on the cost of copper, and cost-plus without blinking is the standard pricing model.
Setting up our power system upgrade from single phase to three phase on a relatively small site cost six figures, and we didn't do anything fancy, and only need the three phase because we use electric heat for safety reasons over wood, and didn't replace 90% of our installed electrical infrastructure.
So I would say if you can't demo it in your house, and if you can't return it at no cost to you if it doesn't work, don't buy it.
RE: Tripp-Lite Their non-desctructive power conditioner (not UPS) protection works on the Hot and Neutral only, no Ground protection. Now, if lightning doesn't strike the wet ground near your home much, might be enough. The competing (similar technology) units (the brand escapes me but someone will chime in) protects all three lines but costs twice as much.
