Question

If you are monitoring a transformer using dissolved gas analysis, which specific gas concentration rising rapidly suggests that an internal electrical arc is burning the solid paper insulation?

Accepted Answer

When the oil in a transformer gets hot, it breaks down and releases gases. This is called dissolved gas analysis. If you see a fast rise in carbon monoxide, it means the paper wrapped around the electrical parts is burning. The paper is the solid insulation that keeps electricity where it belongs. Think of it like this: if you smell burning toast, you know the bread is charring. In the same way, when carbon monoxide spikes, it tells you that a hot electrical arc—a powerful spark of electricity—is eating away at that paper insulation.
