DGA900 Transformer Monitoring and Diagnostic System

General Information

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 maximised and expensive failures to be avoided.

The DGA900 offers discrete on-line DGA and moisture monitoring for transformers and other oil insulated filled electrical equipment. Utilising photo-acoustic spectroscopy (PAS) measurement technology well suited to field application, providing laboratory challenging levels of precision and repeatability. Full 9 gas (Hydrogen (H2), Carbon monoxide (CO), Methane (CH4), Acetylene (C2H2), Ethylene (C2H4), Ethane (C2H6), Carbon dioxide (CO2), Oxygen (O2), Nitrogen (N2)) DGA sampling can be performed as often as every hour including monitoring of the 7 key fault gases employed in all common diagnostic methods and DGA900 offers full gas in oil trending, analysis and diagnostic capabilities through its close integration with GE’s powerful Perception software suite and/or users own software, historian and SCADA systems. Capable of monitoring all sizes of transformers DGA900 is most widely employed for monitoring large, system critical or compromised transformers with a view to extending asset life, preventing unexpected failure and operating on a condition based / predictive maintenance schedule.

DGA900 unit requires no calibration or carrier gases.
