Old Installation Earthing: Safely Grounding Computer Housing, Radiators & Handling 100V Charges

Hello
I have a problem that I thought there would be a lot of answers here, but I couldn't find it. Sometimes touching the casing of the chambers and the radiator or something related to it (I don't know how to write it but you should know what's going on) kicks me quite a lot of electricity. Recently, on the basics of electronics and electrical engineering at school, the teacher said that it is on the computer housing that charges up to 100V can accumulate. And to get rid of it, you need to be grounded. He said that in the case of an old installation, you need to connect the PEN wire in place of the pin. There is only one thing that puzzles me, if I do so and accidentally connect the pin with the L wire, it will be a short circuit. I'm right? And how to do the same grounding as in newer installations? I do not want to ground the whole house, but my room because I have some electronics

read about grounding and zeroing.

in old installations (2-wire), zeroing is used (zero to pin)
in the new (3-wire) there is a separate wire (phase, neutral, ground)

In the case of old two-wire installations, it is permissible to connect PEN in the socket. If you connect the phase wire to the pin, there will be a short circuit and it must be so. Then the fuse is to turn off the electricity. If, for example, the device has a short circuit to the housing, and it is not earthed, then after touching such housing, it will kick in the best case.

and could you make a separate wire for grounding ??

PS: and the lack of grounding is not related to involuntary "receiving" of the radio by my speakers?

If the advice of your colleagues is not enough for you, you can rebuild the installation to TN-S and, consequently, replace the cables with 3 wires, install RDC, ground the PNE division point into PE and N, then it will be like in new installations and of course more expensive
greetings

Because this PEN connection to the bolt is a bit afraid because it's always easier for me to bang
Sorry, you may have misunderstood me, but my point is if I could not attach a cable to a pin and connect something like this to a tube

Under no circumstances should you do this

well, could someone give me some way (apart from connecting the PEN to the pin) so as not to knock the walls and not to change the installation? What to do grounding should I put the cable in the ground? : 0

no cable in the ground will do anything, connection with a cable to a tube, radiator, etc. is prohibited !!!. Connect the PNE (neutral) wire to the pin in the socket and it will be OK
greetings

Oh, and it is not so that if the power company does not offer TN-S standard networks, you can probably make the earth electrode yourself (well, almost ), on new construction sites, foundation earth electrodes can be made, on older ones, there was often a flat tape buried into the ground to a depth of about 2m and a length of probably 10m.

Hello. A colleague of Shulc deigned to describe the earthing system called TN-CS and not TNS (i.e. one where the earthing system is connected to the neutral wire before the fuse box ... but this is just for the sake of accuracy ... it's just about the nomenclature.
I have a theoretical question: is it legal to connect the grounding in the socket to the grounding conductor, next: is it safe? and then what will happen if we connect the old washing machine "franie" to such "something" and one day we put the plug in the "opposite"?

Added after 7 [minutes]:

Tronic, there is no such thing that "flat tape so much and so much in the ground and so or so long" .. it all depends on how far you are from the substation, the quality of the ground ... at the end you have to measure such a ground and then you are sure. If you reach less than 100Ohm between the phase conductor and your earth, you can feel safe. The 30mA RCD will also function properly. Regards.

"Frania" will work the same - the reset is done in the socket, not in the plug.
Regards.

Well, I guess I will, but one more thing bothers me:
what if the device connected to this socket will have the ground and one of the wires connected? does something like that happen?

To carry out "zeroing" you must have a TN-C network - then you connect the PEN wire to the pin, if you have a TT network, you only have the N wire and you cannot zero the pin with it. You need to make a local earth electrode (PE wire)
Regards

sand 1990, You Describe Your Problem You want advice but we don't know
unfortunately the power system / TN-C, TN-CS, TT / a way depends on it
the implementation of effective protective grounding, seemingly seem like
it may not be important, but your health may depend on it, and sometimes
life, so Dont disregard the way to achieve your grounding.
Reading your doubts, I presume that you are not sure of yours
skills, so I advise you to do it by someone who knows anything and knows anything
and finally, he will perform measurements of the effectiveness of electric shock protection.

Simply connect the zero (PEN) in the socket to the pin, when full voltage appears on the housing of the device, it will blow the fuse or circuit breaker (depends on what protection you have). This is the easiest way without breaking the walls, and for protection you can probably use a differential, but I am not sure if it can be used in your network.

No you cant. Every child already knows that the RDC can only be used in a 3-wire installation! And we are not talking about grounding, but about a protective conductor, which, indeed, should be cold at the connection point where it connects with the neutral conductor of the network ... Do not make a fuss here and do not write nonsense here, otherwise exclusive because it confuses the matter and we even talk about audiophiles and other voodoo.

Elmont - you're right I'm not sure about it, and I wanted to do it because I thought it would be fairly easy and safe. Well, if you need someone experienced, I would like a neighbor electrician
thanks for the sharpening

Hello!
Is it possible to perform such a maneuver when replacing a 2-wire system with a 3-wire one: on the L sockets - the left pin (black), N - the right pin (blue), and the yellow-green pin. Bridge the yellow-green installation prepared in this way to N at the beginning of the circuit while waiting for the replacement of the switchgear and installation of the RCD
