Hello all,
This is my first post so hope I'm in the right place for my question!
I sell single-phase frequency invertors that drive variable-speed borehole pumps, a product from Italy - it's single-phase 230v in and three-phase 230v out from the invertor to the pump's motor. This invertor uses a standard plug which the well-driller simply connects to an available wall socket.
About 3% of the installations give problems with the RCD tripping. We ensure it's a 30mA, has no other equipment connected in, and still it trips. I heard this can be a problem with the fast switching in an inverter.... My question: is there a simple filter that I can fit that reduces/removes the earth-leakage problem? Or is there another solution?
