Preventing voltage spikes from inductive loads

[NewFolder]

I posted a question on here a while ago about my powered USB hub malfunctioning when I switched a fan off, and I got the answer that the fan was an inductive load, and when switched off it could create a high voltage 'spike', that was going to the transformer for the USB hub and causing it to malfunction. I was also told that this could potentially damage equipment.

So is there any way to prevent the voltage spike from occurring, or to prevent it from being transferred to other equipment?

You won't stop it from occurring as such, you can minimise the effect by using anti surge devices

Thank you for that.

Do surge protected extension leads protect the devices plugged into it from spikes caused by devices plugged into other sockets? E.g. if I plugged the fan into one socket on the surge protector, and plugged 3 other devices in, would the other 3 devices be affected by the voltage spike caused by the fan?
