E-lesson: DGA status & interpretation: navigate the standards through real cases
Hosted by: Anatoliy Mudryk / Free
The session answers typical questions such as:
- What is the DGA condition of my transformer?
- What is the failure mode?
- What standard shall I use?
A simpler DGA status based on four levels is defined and adapted to each guideline in order to have comparable results independently on the standard used.
A simple graphical method is also proposed to group all the available interpretation methods in a single chart, making the DGA result interpretation intuitive and immediate.
Both the interpretation chart and the DGA status are then used and validated through real cases , including those described in CIGRE TB771.
