Hello, I find it very interesting to put an inductance on the ground wire.
The first thing I have no phase and neutral if not two phases because the transformer that gives us the voltage is something old.
I have installed a stabilizer at the power input and followed by an EMI filter without metal housing.
It is assumed that the earth enters the filter and the inductor is placed in series at the output, which already goes to the terminal strip where all the devices are connected.
What would be the value of inductance, could I do it?
Cheers

Never put an inductance (or resistance) in a Protective Earth/Safety Ground wire.
the Protective Earth/Safety Ground path is always back to the Neutral at the building's AC supply entrance.
the Protective Earth/Safety Ground is never directly to a ground rod.

It depends on the mains distributor's earthing system. You can read about it here: Earthing system - Wikipedia For example, in my place, we have the "TT" system i.e. a copper rod to the ground completely independent from "neutral".
There are some commercial EMI filters that have an inductor in series with the PE. Some of them give schematics. I haven't use one of these but I have personal experience from a conductive EMI type that seems to be affected by the length of the PE wire from the central panel to the wall outlet. Yet to find an opportunity to check it thoroughly...

Wow, that "TT" system is just totally different!
I stand corrected.

From the excellent Jim Brown paper on AC power.
TT system:
One pole of the supply system is connected to one or more electrodes buried in the ground.
Local buried electrodes are used to 'earth' exposed conductive parts of a load installation.
The TT system is a rather dangerous system, since it offers no protection against electrical shock if a fault occurs within equipment.
It is dangerous because fault current through the earth is unlikely to be strong enough to cause a protective device (circuit breaker, fuse) to disconnect the power before a person might die from an electrical shock.
