The grid's version of a jump scare — electricity arriving faster than anything wants it to.
means A sudden, brief spike in electrical voltage above the normal, safe level flowing through a circuit.
from 'Power' traces back through Old French 'pouair' to Vulgar Latin 'potere,' meaning 'to be able' — raw capacity made into a noun. 'Surge' comes from Latin 'surgere,' 'to rise' (the root it shares with 'resurgence' and 'insurgent'), originally used for waves swelling up and over. Sailors spoke of surging seas long before engineers borrowed the word for electricity in the age of power grids — current doesn't rise like water, but when it does, it breaks over your wiring the same way a wave breaks over a hull.
- typical cause
- lightning strikes or sudden grid load changes
- duration
- often lasts less than a millisecond
- real damage
- fries circuit boards before breakers even react
- defense
- surge protectors sacrifice themselves, one spike at a time
