Or....does it's OCPD react before any given component ignition temperature is reached?
What's scary is this notion seems to be an inherent malady from lowly resi wiring up to sub stations....
:lol: I am only laughing because it seems to be that way. BOOM seems to be the language of "yup, something broke"
That what I would expect, but it looks like this type of protection was optional?A turn to turn short would likely be detected by a transformer differential relay. Normally current in should equal current out (corrected for the turns ratio and slight losses) If excess current is circulating inside the transformer from the short the relay will trip. There is also a sudden pressure device which senses a sudden and rapid rise in the transformer pressure that could trip it as well.
All our oil filled transformers get their oil sampled on a regular basis and they can detect if things are beginning to go south in the transformer.
In terms of turn to turn fault this is like creating another transformer winding? The circulating currents heat the shorted section?
