Thanks Mikko!

In your presentation, there is a reference to filters. I assume this means mains electricity / ground filters?

If so, are such easily available within the EU? What are the correct keywords one should go about trying to learn more about them?

Hello again Vasra

A transient filter is normally a capacitor (a condenser) which reduces voltage changes and takes away those spikes (in RF range). These filters can be installed a) in the wall socket b) in the switchboard c) outside the house, around the power cable.

There are several manufacturers and alternatives. Just to list few:

In Sweden I spoke with an electrical engineer Lars Röstlund who is one of the best experts in this area (http://www.rtk.se ). Lars pointed out that many filters are not optimal since they do not 'clean' the electrical circuit. Often the grounding or null wire remains as a problem.

Personally I see that transients should be reduced already in the switchboard or outside the house. Additionally, lighting and devices should be selected/designed i-n-s-i-d-e the house so that they do not produce (much) transients. Good practices:

Any other comments about good / suitable filters or filtering practices?
