I'am new here to this wonderfull site and im glad that i find it. Now i believe each and every one should be creative and and must be happy to spread their knowledge freely every were.
What im asking its simple circuit consisting of a small current transformer that will detect an ac current (from 220V water pump),where the live wire is passing thru its hole.
As we all know that will produce an ac voltage of around (200-300mV) at its leads.
As long as there such voltage, can anyone design a circuit that will drive a relay of 12v and then by using
its contacts to connect an 220V hour meter for example.
