Dissolved Gas Analysis of Insulating Transformer Oil Using ...· PDF filedissolved gas analysis (DGA) which detects the minute levels of gas generated inside a transformer during arcing and hotspot events. DGA allows for the sampling and testing of insulating oil without taking the system offline during measurement. DGA is performed by removing insulating oil from the transformer and sending it to a lab for analysis.[email protected]
