Dissolved Gas Analysis

The single most informative diagnostic test

Dissolved Gas Analysis (DGA) is widely accepted as the most reliable tool for the earliest detection of incipient faults in fluid filled electrical apparatus. Under normal operating conditions very little decomposition of the dielectric fluid occurs. However, when a thermal or electrical fault develops, dielectric fluid and solid insulation will partially decompose. Analysis of the quantity of each of the fault gases present in the fluid will identify fault processes such as corona, sparking, overheating and arcing.
