The Conservator is a cylindrical component of the transformer. The conservator is located at the top of the transformer. The Conservator is designed to act as a reservoir for the transformer oil. The level of the oil in the transformer can rise and fall due to temperature. The increase of temperature can be caused either by a rise in ambient temperature or due to increased load on the transformer.
An increase in temperature causes the oil in the transformer to expand. The conservator provides space for this expansion of the oil. The oil level indicator in the conservator needs to be monitored to ensure that the level of oil does not fall below the alarm limit.
As the level of oil rises and falls inside the conservator, air enters and leaves the chamber. The air may carry moisture which may cause the oil to deteriorate. Breathers filled with silica gels are provided to separate moisture from the aspirated air.
The silica gel turns blue when it becomes saturated with moisture after which it needs to be replaced.
Current Limiting Fuses
Current limiting fuses are used in systems where high fault levels can result in excessive fault currents. The fuses function
as normal fuses; however, they are designed to limit the fault current to low levels when they operate.
During normal operation, the fuse has a low resistance. Read More
