We had our electricity meter changed for a smart meter very recently, and I asked the techie if he could leave the old one with me.

I though that there was the possibility of extracting a current transformer, but no deal.

However the voltage coil can be used as a low power smoothing choke, inductance 20 Henries, DCR about 720 ohms.

Here is the V/I assembly:

I have cut off (brutal) the current sense section and as the meter was 3 phase I now have 3 off free chokes :)
