Flux linkage. Friend or Foe?





What the Flux???

Sorry I couldn’t resist.

Flux linkage can work to your advantage when out in the field.

If you have a coil on the primary burnt out for some reason, you are still able to use that transformer.

What is this dark magic?

Remember how transformers work?  The work on the principle of flux lines cutting conductors and inducing a voltage.

The primary winding that is still connected to the primary line will still cut the windings on the secondary.  It will then induce the voltage needed for the secondary.  There is however a limitation.

Seeing as how you are using only one of the primary windings you have only half the KVA available to you.

It is important to remember how the windings ratings are determined.  Need a refresher?  Go here to watch the lesson on ratings.

Remember, just because the secondary of the transformer can ask for a certain amount of load it is important to make sure that the primary can deliver.
