PARTS OF TRANSFORMER OIL CONSERVATOR SYSTEM BASICS AND TUTORIALS

PARTS OF TRANSFORMER OIL CONSERVATOR SYSTEM BASIC INFORMATION
What Are The Parts Of Transformer Oil Conservator System?


Conservators are usually mounted on one end of the transformer and well above the cover and bushings. Conservators normally have a rubber bladder inside. This bladder expands or retracts due to the temperature of the oil vs. the ambient temperature.

The inside of the bladder is connected to external piping, and then to a silica gel breather. All exposure of the oil to the air is eliminated, yet the bladder can flex.

The oil supply piping, from the conservator to the transformer, should have at least one valve. The valve(s) must be closed during the vacuum cycle as the vacuum will try to pull the rubber bladder through the piping.

The oil piping should have been cleaned prior to installation and the valves inspected. The conservator should have an inspection cover and the inside bladder inspected. While making this inspection, also check the operation of the oil float.
