Having said that, electricity surges in need of a lightning strike are typically self-limiting. One example is, In the event the computer's electric power provide is unable to tackle the surge, it is likely to are unsuccessful before the parts it powers are broken.
Surge protection: Making use of the exact same tools and protocol we use to test surge protectors, we zapped Every UPS with five,000-volt electricity surges, measuring what number of volts they Permit via.
