TT: Transformer neutral earthed and frame earthed.
In this earthing systems, the supply source has a directconnection to earth
All exposed conductive parts of the installation also are connected to an earth nelectrode.
A TN-S earthing system has seperate neutral and protective conductor throught out the system
The supply source is directly connected to earth.
All exposed conductors parts of an installation are connected to a protective conductor PE via the main earthing terminal of the installation
TT : the source and the load separately connected to earth, there is no connection between earth and neutral too.
TN: the source connected to earth and the load is connected to the same earth
there is TN-C where common cable is used for earth and neutral, TN-S separate neutral and earth but same as source's earth, TN-C-S there is common point for earth and neutral but they both have cables.
TT System , the neutral is earthed at Transformer side only , but in TNS the neutral is earthed at load as well
