On-line DGA & moisture for 3x single phase transformer
Dissolved Gas Analysis (DGA) and moisture measurement of the insulating oil are recognized as the most important tests for the condition assessment of transformers. Multi-gas DGA has traditionally been confined to the laboratory environment and infrequent off-line manual sampling, forming part of time based maintenance strategies. As the average age of transformers globally continues to rise, the possibility of rapid ageing, unplanned outages and even catastrophic failure between off-line tests also increases, leading many asset owners to adopt on-line DGA monitoring of equipment to
increase network reliability.
The Kelman™ MULTITRANS offers discrete multigas on-line DGA and moisture monitoring for three adjacent single phase transformer tanks. Utilizing photo-acoustic spectroscopy (PAS) measurement technology, well suited to field application, it provides laboratory challenging levels of precision and repeatability. Full 9 gas oil sampling and analysis can be performed as often as every hour on a single tank and up to once every three hours on the three tank configuration.
Through close integration with GE’s powerful Perception™ software suite and/or user’s own software, historian and SCADA systems, the MULTITRANS offers full gas-in-oil trending, analysis and diagnostic capabilities including various diagnostic methods prescribed by international standards.
