So is getting a standalone UPS or AVR or Surge Protector or a combo of all, worth it or not? To protect against power surges, fluctuations, random cut, lightning, etc.
Where was one post that first defines a threat?
Where was one recommendation that cites even one fact or spec number that justified that recommendation?
Without answers to both, a recommendation is hearsay. Likely urban myth. And often someone only educated by advertising.
For example, that Belkin. It was recommended only because someone has one. And due to more robust protection inside electrionics. he had no failures.
View Belkin's spec numbers. How many joules does it claim to absorb? Hundreds? A thousand? Destructive surge can be hundreds of thousands of joules. Since they ignored all numbers, then a near zero protector was called 100% protection. Such mistakes are routine when one ignores spec numbers.
We did this stuff. Actually traced a surge that hunted for earth ground destructively via an adjacent protector. That protector gave a surge a paht to earth that 1) bypassed protection in the computer's PSU. And 2) obtained earth ground by outgoing via the network cable. Note what any recommendation also discusses. To be damaged means a surge must have one incoming path. And another outgoing path. That current flows simultaneously. Often damage is on the outgoing path.
Many will assume a surge was incoming on the network cable, did damage, and stopped. Electricity does not work that way. But it does not matter when observation results in conclusions. Then just knew by not first learning how surges do damage and what a protector must do.
The Belkin is electrically equivalent to that protector that compromised protection inside the adjacent computer.
Many other potential anomalies exist. Each one requires separate consideration. Nothing protects from all anomalies - despite so many who recommend a magic box to cure all.
Only surge protection found in every building that cannot have damage is located when wires enter the building. With a low impedance (ie 'less than 3 meter') connection to single point earth ground. Then no one need unplug or power off when storms approach. But this solution is proven by sceicne and over 100 years of experience; not in advertising and hearsay. Most do not even know of what is THE most important compnent in any protection system: single point earth ground. Because, and again, protection is always about - numbers - where hundreds of thousands of joules harmlessly dissipate. A number that only the fewer and informed will discuss.
First, which electrical anomaly concerns you. Each must be discussed separately - with numbers. Especially since most are solved by completely different solutions.
