FAQs
What is the purpose of a DGA tester?
A DGA tester acts as a “blood test” for oil-filled electrical equipment, detecting gases that indicate internal issues, such as aging or stress in insulating systems, without needing to open the transformer.
Which gases do these devices typically monitor?
The key gases monitored are:
-
Hydrogen (H₂): Indicates partial discharge or low-temperature overheating.
-
Methane (CH₄), Ethane (C₂H₆), Ethylene (C₂H₄): Signs of thermal issues at varying temperatures.
-
Acetylene (C₂H₂): Critical for high-energy arcing (>700°C).
-
Carbon Monoxide (CO), Carbon Dioxide (CO₂): Often related to overheating or insulation degradation.
How often should DGA testing be performed?
For healthy transformers, annual testing is standard. Increased testing frequency is needed if fault gases are detected or the unit is aging.
What is the difference between Lab (Offline) and Online DGA?
-
Lab (Offline): Manual oil sampling for detailed lab analysis.
-
Online Monitoring: Continuous, real-time on-site monitoring for data trends.
How are the results interpreted?
Results are analyzed using graphical methods like the Duval Triangle, Rogers Ratios, and Key Gas analysis to diagnose specific faults.
Can DGA results be misleading?
Yes, poor sampling techniques or contamination can skew results, causing false readings. Also, certain equipment like OLTCs may cause gases to migrate, leading to misdiagnosis.
What is the difference between DGA and Oil Quality tests?
DGA focuses on detecting internal faults in the equipment, while Oil Quality tests (e.g., dielectric strength, acidity) assess the condition of the oil itself as an insulator and coolant.
