Zig Zag Grounding Transformer Technical drawings
Reasons for the Necessity of Grounding Transformers
- They serve as a measuring point for monitoring faults.
- They help reduce the intensity of transient over-voltages that may arise during a ground fault re-strike.
- They may include a low-voltage auxiliary winding, allowing them to act as a local power supply for substations.
- They facilitate the connection of phase-to-neutral loads when necessary.
- By offering a low-impedance route to the ground, they assist in keeping the system neutral near ground potential.
- They are employed in wind farms to protect against faults in ungrounded cables.
- They can supply ground-fault current during line-to-ground faults.
