The secondary voltage (421-03-07) of a power transformer is the output voltage of the transformer.
Some configurations may be complex, see windings=* for more information.

For a step-up transformer involved in a power plant, the secondary voltage is higher than the primary voltage since the power outputs on the high voltage side.

Possible Tagging Mistakes

  • voltage-high=* ‒ For step-up transformers (power generation mainly)
If you know places with this tag, verify if it could be tagged with another tag.
Automated edits are strongly discouraged unless you really know what you are doing!
  • voltage-low=* ‒ For step-down transformer (consumption, industrial...)
If you know places with this tag, verify if it could be tagged with another tag.
