Is electrical engineering a stressful job?
Yes, some electrical faults are hidden enough that we can’t even understand what is going on. But this is not the only rule of being an electrical engineer.
The point is, with more and more experience you can troubleshoot faults faster. And the more faults and issues you face and solve the more comfortable you feel with the feature faults.
One of the rules of electrical engineering is, that electrical faults are easy to fix but hard to be discovered. Imagine a large machine with many electrical control wires and cables. If one main wire gets damaged, the machine may stop.
Fixing the wire is just to repair a small portion of the wire and you are done. However, it may take hours to detect the damaged cable and its location.
Another example, In my work we have a very long overhead power line. Sometimes we get reports that the power is off in some locations.
We may spend up to 4 hours searching the OHTL network to find a blown fuse, cut wire, or a broken insulator. After 4 hours of searching, we just need 15 minutes to replace the blown fuse and we are done. You can imagine the stress we face in these 4 hours.
