MESSKO® MTRAB® 2.5 DB200 dehydrating breathers with β control system

Self-learning system, which is recommended for use with transformers (power transformers, generator step-up transformers, phase shifters, shunt reactors) with cyclic loading. In addition to monitoring the humidity, it determines a time window in which the oil expansion vessel expels air and the dehydrating chambers are regenerated.

Maintenance-free dehydrating breather in use

Vacuum technology at GSE in Georgia: In Georgia, two transformers have been updated for increased safety and reliability. To ensure maintenance-free operation, the MESSKO® MTRAB® DB100 and MESSKO® MTRAB® DB200 dehydrating breathers were used.
