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 ...

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.
SWER is a viable choice for a distribution system when conventional return current wiring would cost more than SWER's isolation transformers and small power losses. Power engineers experienced with both SWER and conventional power lines rate SWER as equally safe, more reliable, less costly, but with slightly lower efficiency than conventional ...

However, the connection to the Earth itself is always relevant, since the Earth forms a mildly conductive surface that we cannot easily avoid (e.g. a person standing on the ground and touching a metal appliance or tap or building-framework that is connected with the electrical installation's protective earthing system). In TT systems the ...
