Answer Posted / sajid hussain
When load increase on the secondary side of the
transformer,heat produced which decompose the oil i.e
hydrogen and carbon. This lightly Hydrogen gas entered in the
Relay Dom and produced pressure on oil at the upper side. The
oil level of relay housing decrease.If the heat produced is
too higher due to current flow or arc the decomposition of
oil is also high which cause the more oil level down in the
relay housing.
