    Hi!

    I have an old refrigerator producing quite a lot of high-voltage impulses
    while turning on the pump. I don't want to buy a new one right now, because
    I don't know how long I will stay here. So, in the meantime I need to
    protect my other equipment from any potential damage, which means adding a
    filter between the fridge and the power outlet. Can anybody recommend a
    simple circuit?

    (Yes, yes, I googled, but didn't find anything useful)

    Thanks in advance!

    Ron

    Thanks! I googled with "AC cleaning filter" or something like that. Your
    suggestion is of course better.

    Would be more work: separate protection for PC, TV, radio etc. Thanks
    anyway.

    Sounds like an excellent idea. I'll check the local whiteware shop and see
    if they've seen such a device.

    On the other hand it surprises me that nobody came up with a schematics of
    such a device. One would expect it to be a rather standard solution for
    people with the know-how. I am just a perpetual novice with a huge
    fascination for electronics.

    Thanks!

    This is really clever! I tried all kind of different combinations of AC,
    cleaning, circuit etc. without significant result. Your search terms indeed
    gave a usable result straight away!

    THANKS!
