Out here (South Africa) we are plagued with the electricity supply company merrily turning our power on and off whenever they like. I think it advisable to use surge protectors on many plugs to protect ordinary household devices, but how do I know if the surge protectors are still doing what they're supposed to do? I have some that have no warning light or other indication whether they're actually working properly or not. Is there any way of testing whether a surge protector is doing its job or is just conducting the current without providing any protection?
Thank you.
