Explanation: "blind earthing point of the transformer and a five-wire electric network is applied"
The transformer is grounded, by some means, to the soil on the installation site.
Ground is occasionally called "earth ground" when it goes to the dirt outside a building, to distinguish it from "Circuit ground" which refers only to the wiring on a circuit board ot inside a single device.
