  • Learn | OpenEnergyMonitor

    Like any other transformer, a current transformer has a primary winding, a magnetic core, and a secondary winding. In the case of whole building monitoring, the primary winding is the live or neutral wire (NOT both!) coming into the building, that is passed through the opening in the CT. The secondary winding is made of many turns of fine wire housed within the transformer case.
