A small early-stage problem in a system that hasn't fully failed yet.

It's not a short circuit.

It's not anything big that happening.

So why would I care about that? It's not damaging the system.

It's not unsafe for humans who are interacting with the systems.

But if you take the long-time series of events happening, you will see a small spike, another small spike, spike, spike, spike, and then it goes boom.

Just like the Northeast Blackout of 2003.

A tree touching a power line.
