Knowledge of the condition of transformers is essential for all electrical networks and on-line monitoring of transformers is an increasingly vital component of successful asset management programs. The information provided by multi-gas on-line DGA allows valuable asset capabilities to be maximized and expensive failures to be avoided.

Dissolved Gas Analysis (DGA) and moisture measurement of the insulation oil are recognized as the most important tests for condition assessment of transformers. Traditionally performed in a laboratory environment, the Kelman™ MINITRANS provides for on-line discrete DGA monitoring of key gases associated with arcing, cellulose degradation and general fault conditions.

The MINITRANS facilitates entry into discrete on-line DGA and moisture monitoring for transformers and other oil insulated filled electrical equipment. The MINITRANS gives insight on developing faults, paper degradation and electrical arcing. It provides trending of gas-in-oil through its close integration with GE’s powerful Perception™ Fleet software suite and/or user’s own software, historian and SCADA systems.

At a price that facilitates higher volumes of monitor deployment, The 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. It helps asset owners incorporate on-line 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.
