additional Power protections for electrical outlet with only nuetral and live wires ?

[Mezoxin]

all households where i live have their electrical outlet with no ground wire , ofcourse apart from the electrocution hazard ,and as I dont have the authority of making modifications to add a ground in my apartment , i was wondering what kind of protection i can use to protect my PC against damages from surges and brownouts , and i dont need uninterrupted power.

A surge protector, although not all of it will be functional due to no ground; for brownouts a voltage regulator, although the supply itself should be fine if it can cover 110V to 220V without a selector switch (as with most modern supplies).

I only know surge protector in power strips but that diagram is something you install at your main panel ,how about for a 3 phase power main power source what should be the layout ?

i was thinking of something like this just for the pc

The diagram was just to show what you would lose by not having a ground connection for single phase (why the interest in 3 phase?)

A remote switch is just one more thing to maintain, lose, break.

I have a 3 phase main power 380v distrubuted in my household to 3 pairs of nuetral and live giving each 220V , I thought the diagram was something you can install at the main power panel between the phases and nuetral

So the surge protector in my situation would draw the excess voltage towards the nuetral line instead of ground (which i dont have) ? which is not ideal because ?

Because if your neutral and live surged together to say 500V, there would be no relative difference and so no suppression.

All?

Are you sure about that?

yes that 3rd ground wire on the plug has no where to go
The Problem stems out from the electrical regulatory authority in egypt , when their representatives install and commision electricity to households , they dont care if you have a ground wire and pit or not for your household , they only install the live and nuetral wires connect them to the meter and thats it , accordingly all the wiring in housholds and electrical outlets are configured accordingly , even in the most luxurious private resorts and compounds you would find it configured the same , So neither the regulatory authority requires grounding nor the end user is aware of the importance of grounding , So the end result its not configured in the wirings and electrical outlets unless you ask for it specifically
