Breather is used for t/fr.this is a container in which
silicon cristal is packed .it used to provide the dry air
for the t/fr.

Answer / d m fulzele

Breather is use in transfoimer.
Due to continuous change in load conditions, oil in
transfomer comprased or expands. when oil comprased it take
external air in through breather. breather contains silica
gel which is used to absorb the moisture in air and supply
dry air in transformer conservator tank. If moisture
contained air passes in to the tank will mix with oil and
the BDV of oil will be low and hence the life of
transformer.

bit confused - am i correct in thinking that to determine line to line voltage in a star config 110v 3 phase 4 wire distribution system i would use a voltmeter? I have a circuit configured as an unbalanced load, consisting of three incandescent lamps (1x40w, 1x60w, 1x100w - all 110v rated)connected in a star configuration to a 110v 3 phase 4 wire distribution system. I want to find out what types of meters i would use to obtain: a) each line to line voltage b) the line to neutral voltage across each load c) current flowing in each line and load d) current flowing in the neutral conductor e) power supplied to the loads im assuming i would be using ammeters in series along each line and voltmeters in parallel across each line to neutral? Also how could i predict these meter readings before taking them and with which formulae? Any help would be greatly appreciated A.
