I can only imagine what might happen to the UK or some European areas if they got hurricane force winds for 12 hours...
BBC often makes this point when FL is without power after a hurricane. America still puts wires overhead. Much of Europe put those wires underground.
240 volts is better? Learn what happens inside every electronics device. Power from 120 or 240 volts is still converted to well over 300 volts DC. Makes no difference which voltage is input. Electronics is still powered from well over 300 volts.
Line conditioning? Does not matter how 'clean' that incoming power. Power supplies convert it back to 'dirtiest' power. Converts AC to DC. Then converts that DC to radio wave power. Power is made even dirtier before it is converted to low voltage, rock solid, DC voltages. Most who recommend magic solutoins on a power cord have no idea what goes on inside a power supply.
Now, I am not sure what you are trying to solve. For example, that UPS is provides temporary and 'dirtiest' power during a blackout. It does nothing for hardware protection. It provides time for one to finish and save unsaved data. Or to avoid waiting for a computer to reboot.
Its surge protection is near zero. Just enough above zero so that advertising can hype it into 100% protection. MOVs do not absorb surges. Never did. But most have been told that by advertising and liars. Makes learning reality that much more difficult. Learn the difference between a UPS (for temporary power) and something completely different - surge protection.
What exactly are you trying to solve? Which electrical anomaly is problematic to what? You cannot solve something without first defining the problem.
A UPS is made as cheaply as possible. Its battery life expectancy is three years. It outputs power so 'dirty' as to even harm small electric motors and power strip protectors. Since all electronics are already so robust, that same 'dirtiest' power is ideal power to all electronics. Now what are you trying to solve?
