Below given is an example of connection for measurement of 2 transformer systems (differing in voltage and number of phases and wires) by
one unit (example of connection of EMU2-RD4-F-4W).
Circuit 1: primary voltage 63.5/110V, primary current 800A (EMU2-CT5-4W)-------800/5A current transformer is separately necessary.
Circuit 2: primary voltage 63.5/110V, primary current 250 A (EMU-CT250)
Circuit 3: primary voltage 254/440V, primary current 600 A (EMU-CT600)-----------
Circuit 4: primary voltage 254/440V, primary current 1000 A (EMU2-CT5-4W) -----
transformer are separately necessary.
