Questions

Question
I would like to know about the grounding of this transformer.
How can I connect the ground of my equipment to the secondary coil.
Answer

Dear customer,

Thank you for your message.

The transformer you refer to is a three-phase to single-phase transformer (10 kVA, 400 V to 230 V), enclosed in a metal protective box. The secondary side (230 V) does not include an integrated neutral-to-earth connection, which means that the grounding arrangement must be completed externally according to the installation's requirements.

If your equipment requires grounding, you can do the following:

  • Connect the protective earth (PE) wire of your equipment directly to the ground terminal (usually marked) inside the transformer enclosure.

  • If a TN or TT system is needed, you may need to create a local earth reference by connecting the negative or midpoint of the secondary (depending on wiring) to ground — this must always be performed and validated by a qualified electrician in accordance with local regulations.

⚠️ All electrical equipment must be installed by qualified personnel. The final grounding configuration must be designed according to your installation's electrical code and safety requirements.

Please feel free to contact us if you need further assistance.

Best regards,
