[Malvern] Electrical Intreference

[Ian Pascoe]

Hi All

For any sensitive electrical equipment it is generally recommended to have
an RF filter somewhere on the mains feed to remove spikes that come in over
the mains power.

If you are converting from AC to DC power will these spikes still be there
after the conversion?

If you transform the power down from 240v AC to say 12v AC does the spikes
decrease in line with the reduction or do they stay the same?

And lastly, I have read that if a neighbour uses the mains ring to provide
data transfer for either audio or computer networks, that extra information
leaks back out into the mains distribution.  Would an RF filter remove it or
do you need something else?

Sorry about the vagueness of terminology - I know what I mean but can't
think of the proper worms!

Cheers

Ian
