when a transformer is over heated ,more hydrogen content is
released from the transformer oil when burns when reaches
air at the top of tank ...so conservator is used to allow
hydrogen flow upto it between which a BUCHolz relay get
operated.

Answer / s.murugesan

Two main roles of conservator:
1) Due to temperature variation the transformer oil
volume varied it was compensated by conservator and will
allow pure air inside the TR.
2) To maintain the oil level inside the
transformers.

Answer / sks

Two main roles of conservator: whenever high electrical
stress are produces inside the transformer due to fault
then temprature raise of oil it gives contraction effect &
gases also produced inside the main tank then it takes a
path to release the pressure via bucholze reley to the
conservator & breather releases the gas.
oil possible to store inside the conservator as per
capacity.

reserve oil tank is know as conservator

Answer / vijai

Whenever there is a rise or fall of oil temperature in the main tank due to ambient temperature differential or due to rise in winding temperature,the oil volume increases or decreases then the oil flow from main tank to conservator or vice versa is the main function of conservator.Required air flow from or to the Conservator is through breather.

Answer / varun

Oil filled trasformers with a conservator,an oil tank above the transformer,tend to be equipped with the bucholz relays.These are the safety devices that detect the build of te gases,acetylene,inside the transformer,due to te corona or electric arcs in the windings and switch of the supply...
Transforms without conservators usally equipped with the pressure relays wich as similar function as te buchholz relay...

1 Answers   BSL,

HELLO EVERYONE, I RECENTLY HAVE FOUND ONE PROBLEM, I WAS TAKING NO LOAD TRIAL OF AN HT MOTOR 920 MOTOR , 1440 RPM , 6.6 KV, WITH AUTO TRANSFORMER. AT 450 V, LOAD WAS 40 AMP AND SPEED WAS 250 RPM. BUT AS WE INCREASE VOLTAGE FROM 450 TO 480V, LOAD BECOME 41 AND SPEED REDUCED TO SOME RPM . SO WHICH PHENOMENON ACTED HERE FOR REDUCING SPEED.?? AND IS IT HAPPENING ALWAYS OR IT IS RARE? I ALSO HAVE FACED SUCH PROBLEM WITH FEW LT MOTOR ALSO.
