3.Working of conservator tank.?

Answer Posted / suseendran

1. Conservator is for maintaining the oil level in the
transformer. i.e oil level in the transformer
increases(expands) during summer or full load and the same
decreases(compress) during no load or winter. Conservator
has to accommodate/ provide to maintain oil level full
inside the transformer.

2. As said above when thermal compression of the oil
happens, oil flows from the conservator tank to transformer.
During this air has to fill the remaining part of the
conservator. Breather is the passage by which air enters the
conservator(compare to our respiratory system). Hence the
name BREATHER..
