In a TT (terra–terra) earthing system, just as with a TN system, there is a direct connection to Earth at the supply transformer. But, unlike TN, the exposed-conductive-parts at the consumer installation are independent from it, instead having an entirely separate connection to Earth via a local earth electrode (sometimes referred to as the ...

An isolated ground (IG) (or Functional Earth (FE) in European literature) is a ground connection to a local earth electrode from equipment where the main supply uses a different earthing arrangement, one of the common earthing arrangements used with domestic mains supplies.
A grounding transformer or earthing transformer is a type of auxiliary transformer used in three-phase electric power systems to provide a ground path to either an ungrounded wye or a delta-connected system. [1] [2] Grounding transformers are part of an earthing system of the network.
