Maintenance-free dehydrating breathers
 
The MTRAB® 2.5 DB100 with alpha-control is a condition-controlled system, recommended for use on tap changers, arc suppression coils, air-filled cable terminal boxes and traction transformers. The desiccant is regenerated depending on the condition. Silica gel fill level: 1,1 kg with α-control.
Good to know: The main function of dehydrating breathers is to dehumidify the ambient air. As a result of the thermal compression of the insulation medium, the ambient air flows from the environment to the expansion tank of the transformer and tap changer (referred to as inhalation). During inhalation, moisture must be prevented from penetrating into the equipment with the air flow, as this reduces the insulating effect due to the contamination of the insulating medium.
 
The MTRAB® 2.5 DB200D with beta-control is a self-learning system, recommended for use on transformers with cyclic loads (generator transformers, network coupling transformers, phase shifters, reactors, HVDC transformers). In addition to monitoring the humidity, the device determines a time window in which the oil conservator exhales and the desiccant is regenerated. Silica gel fill level: 2 x 2,2 kg with β-control.
