Earthing transformers and single-phase transformers (including traction)
Earthing transformers for protecting equipment and personnel during earth faults, and single-phase transformers for networks and railway traction. The earthing transformer creates a low-impedance path for earth fault currents.

Description
An earthing transformer is connected in a network where the neutral is unavailable or isolated, and the earth fault current flows through it along a low-impedance path. The protection receives enough current to operate, and the equipment and personnel are protected during a fault. Single-phase transformers are used in distribution networks and in railway traction applications. The parameters of both types are selected for the project.
