Tell me how best to make grounding in the house, I lay the wiring with grounding, and all the wires will come to the switchboard with the ground, but I read a lot that it is necessary to do the balancing of potentials, and so that in the event of a break in the wires on the poles, a lot of voltage does not come into the house, then you need make a separate grounding circuit for the house and connect all groundings to it in the distribution board in order to protect yourself, or is there any other options? How is it correct?
I understand that the zero under the support is grounded? Not the fact that it is of high quality, and most likely there, as usual, one pin was driven in.
As for the high voltage, we are talking about phase imbalance, and little will save from it when zero burns out on the TP. Grounding is necessary first of all in order to avoid the appearance of a dangerous potential on the housings of electrical appliances!
I advise you to read these articles:

yes, the zero under the support is already grounded, there are three corners 4 * 40 * 4000 driven in and connected by a 4 * 40 strip, they came to measure the resistance, everything is within tolerance, less than 30 ohms. But over time, of course, anything can happen. I understand correctly, it is necessary to re-ground at the house and enter it into the switchboard in the house, and connect the grounding to the bus from all sockets.
What is the best way to re-grounding_ to buy a ready-made kit from a copper pin, or in the same way as at the post, with corners?
