When the transformer is over-loaded is due to short circuit or other faults, winding generates heat that result increase in the temperature of the insulating oil in main tank of the transformer. Then, the volume of insulating oil inside main tank of transformer also increases.
Hence, here used a metallic cylindrical tank called conservator tank to provide sufficient space for the expanded insulating oil to . Conservator tank act as a reservoir for the expanded insulating oil. In this way conservator tank protect transformer from explosion due to expanded insulating oil.
Conclusion
Hope, you have clearly understand about the function of conservator tank in transformer and why is is important for a transformer. Make sure to leave your opinion about this post in the comment section below.
