What are surge voltages and what harm do they cause?
Surge voltages are short, pulse like, voltage peaks with steep rising edges and are also known as transients.
The origin of these transients can be external, i.e lightning, but is much more likely to be caused by your own equipment, i.e switching of motors or transformers or the interruption of a short circuit by protective measures.
