Not sure how to account for the wrong'un. Perhaps a spike in the

Surge protection will protect your computers and instruments against
electrical surges and nothing more. What you really need is a UPS
(uninterruptable power supply) that has power smoothing capability to
ensure your equipment is not bothered by electrical noise on the wires.
