Earthing and Grounding or Protective Earthing

  1. Oct 20, 2015 #1
    1 “earthing” for bonding of equipment and circuits to common plant
    earth electrode potential,
    2 “protective earthing (PE)” when this bonding is required for personal
    safety provisions
    3 “grounding” for interference suppressing bonding of screens, sys-
    tems with ground level
    4. low-impedance earthing ?
    5.primary earthing system and secondary earthing system what is that?
    6.earthing electrode or mesh net earthing electrode ?

    very confusing , simple but very informative help required ?

    i will be very very thankful to you guys.

    I think you should look up the regulations that apply to your home country if you want the answer to this. The IEE 'Wiring Regs" are a good reference for the UK.

    This really is about 20 pages of info and background - can you ask one specific question and I am sure plenty of the members here would be eager to discuss, but this is is just too random.
