Transient Symptoms - Electronic Equipment

When electronic equipment is exposed to a transient, a number of things can happen. The first is equipment disruption. Garbled data may come up on the screen or the system may lock up. This may be inconvenient, but there's generally no damage.

The second thing is equipment degradation. If transient activity is fairly constant (i.e., spikes are happening all the time), then system components such as the power supply rectifier or actual integrated chips may deteriorate. This means that, while they may not be affected today, they may be affected tomorrow, or next week, or next month.

Third is the actual destruction of components. This is always the most obvious. Something in the equipment starts smoking or there may be a noise like a pop or zap. This almost always means trouble.
