MR develops vacuum resistant DGA monitor
Maschinenfabrik Reinhausen GmbH (MR) has developed a DGA monitor with full vacuum resistance.
The MSENSE® DGA 2/3 online analysis device was tested at 5 Pa (0.05 mbar abs.) over 48 hours. Vacuum resistance was confirmed by a subsequent test at 100% functionality.
One of the benefits of the device is that reinstallation or shutting off of transformers during the vacuum drying process or during filling is not necessary. Leakages, malfunctions in the process or additional expenses can thus be avoided.
According to experts and international standards, hydrogen, carbon monoxide and moisture in the insulating oil of power transformers are the primary early indicators of potential thermal or electrical damage to the transformer (IEC 60475, IEC 60567, ASTM D 4057).
The MSENSE® DGA 2/3 aims to offer a crucial benefit for operational safety based on continuous monitoring of these early indicators for identifying thermal and electrical faults in oil-filled, paper-insulated power transformers.
Additional trend detection, combined with recommended courses of action, allows the lifetime of the equipment to be significantly extended.
