hi,
i would like to know how to measure perfect grounding in installation
of telecom systems.


As another reply states, there are no such thing as a perfect groundPERIOD

You have to define your need of grounding. What do you want to achieve etc.

You can create a "good enough" or "adequate" grounding in conformance with
your spec or demands.

A health and safety approach on grounding is not necessarily enough to
secure operation in a tropical thunderstorm.

However.

The easiest way to find suitable material on grounding etc for demanding
specifications is to look on how to EMP proof a computer installation.

EMP stands for "ElectroMagnetic Pulse" and is a "biproduct" - or in modern
weapons, the primary product of thermo nuclear weapons.

The quest for a "perfect grounding" does not necessarily protects from EMP
and EMP protection does not necessarily achieve a "perfect" ground.

Again - However... Following the strict guidelines on the "ABC" of EMP
protection, you will be forced to secure such a grounding that any EM
pulses or EM noise will be unable to damage your telecom equipment or
systems. Even if you have a self contained ground separated from
the "natural" ground, you only have to connect your floating, EMP secured
ground to the natural ground. Bear in mind that the EMP protection is
cancelled that way but as your intention is grounding

Grounding a RF installation is a different matter but I believe that you are
asking for a telecom grounding rather than antenna grounding.
