TT system
T =
Direct grounding of a point (station ground)
T =
Exposed conductive parts directly grounded, independent of
grounding of current source (station ground)

TT mains system
The EMC requirements are only observed through specific measures (incl.
special mains filters).
Mains with grounded outer conductor (Corner-grounded delta mains)
I =
Isolation of all active parts from ground, connection of one
phase ‑ generally phase V - to ground or via an impedance R
E
T =
Exposed conductive parts directly grounded, independent of
grounding of current source (station ground)
