An earth is each other in application. installed primarily to protect human life, and for this reason it is referred to as the protective earth (PE) conductor.

The braided mesh should be sufficiently Electrical and electronic systems must be designed such that large and also be as thick as possible.

7 Earthing and shielding | Earthing of shielded cables In practice, the shield is still often twisted and connected to a terminal point. There is very high attenuation (voltage drop) on these connections, especially for high-frequency interference. Therefore, this type of shielding should not be used, even for short cable lengths.
