A voltage swell is a surge (increase) of voltage above 110 % of the rms magnitude in your power grid. The duration can be between ½ cycle and one minute. (EN 50160)

Transient voltages are short time peaks in the a.c. power supply. They typically last a few milliseconds and the voltage can reach several thousand volt. A transient is by definition shorter than half cycle.
