MINITRANS Hi-pot Cost-effective on-line DGA & moisture for transformers

Applications
Multi-Gas DGA has traditionally been confined to infrequent off-line laboratory analysis, forming part of time based maintenance strategies. Globally the average age of transformers continues to increase, whilst in comparison to historical experience a larger percentage of new transformers encounter faults in their early years of operation. This means the possibilities of rapid aging, unplanned outages and even catastrophic failures between off-line tests also increases leading many asset owners to adopt on-line DGA monitoring equipment more suited to condition based/predictive maintenance strategies.
The MINITRANS facilitates entry into discrete on-line DGA and moisture monitoring for transformers and other oil insulated filled electrical equipment. Discretely measuring 3 key gases: Hydrogen; Carbon
Monoxide and Acetylene; plus Moisture, MINITRANS gives insight on developing faults, paper degradation and electrical arching providing trending of gas-in-oil through its close integration with GE’s powerful
Perception software suite and/or users own software, historian and SCADA systems. At a price that facilitates higher volumes of monitor deployment, MINITRANS can be utilized to monitor any size of transformer but is most widely employed to expand multi-gas on-line DGA coverage beyond the typical candidates of large, system critical or compromised transformers helping asset owners incorporate online DGA across a larger portion of their fleet, with a view to extending asset life, preventing unexpected failure and operating on a condition based/predictive maintenance schedule
