Dehydrating breather is a device used to remove moisture and desiccate the air within transformers or oil conservators of mutual
inductors. Installed in the air inlet port of transformers or oil conservators of mutual inductors, it mainly works to keep the transformer
oil dry and clean.
During normal operation, the air flowing to the oil conservator is guided over the drying agent (silica gel) which then dehydrates the air. The degree of air moisture in the pipe is measured continuously with a moisture sensor and the results are forwarded to the electronic controller.
If the moisture content (% rF) of the air in the pipe exceeds a certain specified value, the self-regulating heater element in the silica gel chamber is activated. The water vapor escaping from the silica gel condenses on the specially designed bottom element and drips out of the stainless steel filter.
The temperature sensor is used by the controller to monitor the correct operation of the heating element. An additional heating system (optional) can also be used to prevent the filter system from freezing when outside temperatures are low.
The measured temperature value of the pipe line (dehydrating breather) is output by the controller as an analog signal. Malfunctions of the controller or the heating system are indicated on a fail-safe, continuously powered contact. Many power companies have started retrofit programs and are replacing conventional dehydrating breathers with the. The perfect solution for these retrofit projects, because it is available in many different flange designs!
