The transformer will have to be taken out of service, and topped up. Usually, this would also be a good opportunity to test the oil for contaminants.
no,hermetical transformers do not have conservator.
If the temperature in a sealed transformer rises but the pressure remains constant, it may indicate an internal fault or problem causing excessive heating. To address this issue, you should immediately shut down the transformer, investigate the root cause of the temperature increase, and take corrective action to prevent further overheating. It is crucial to ensure the transformer is safe before resuming operation.
Hermatically sealed transformer is a transformer design which has no conservator. Here the dielectric insulating fluid in the transformer tank is completely sealed and is in zero contact to the atmosphere. This type of transformer is used in applications where the transformer is to be installed in harsh climatic conditions(smoke,pollution,dusty environment,etc) or user prefers low maintenance transformer. The design avoids air in the transformer tank therby avoiding sludging and oxidation of the dielectric fluid. Hence it would be safe to say that these transformers need no maintenance of the dielectric insulatating fluid(usually Oil). Normally these type of transformers are accommodated by devices that measure heat related volume variations. Gas cushion is used to compensate the volume variation due to heat. Normally the gas is nitrogen. This gas is thermally uncoupled from the dielectric liquid.
That depends on the model of the transformer. I have seen transformers that required 7500 liters and some that needed 2,5 liters.
breather to observed moisture from the tank and explosion vent will works when the moisture will get observed in the tank then it will explodes from the explosion vent by breaking diaphgramAnswerThe breather allows air to enter and leave the transformer's sealed tank as the transformer oil contracts or expands. The breather is fitted with a silicon-gel chamber to ensure that any air entering the tank is dry. A viewing portal allows the viewer to determine whether the silicon gel crystals are still active.The explosion vent is a large-diameter tube, usually located at the top of the transformer tank, sealed with a frangible plate or diaphragm. Should an explosion occur within the transformer due, for example, to a catastrophic short-circuit fault, then the blast of the explosion will be allowed to escape through the explosion vent, rather than causing the transformer's tank to explode.

It is sealed simply to protect it.
A candidate for a banking position can get bonded if they have a sealed conviction from a juvenille case. Sealed convictions are not open to anyone other than the judge that sealed it and it takes a judge to open a sealed conviction.
The Sealed Angel was created in 1873.
