CT Ratio Check

CT Ratio Check measures the primary to secondary CT ratio. Channels 1, 2 and 3 are connected to the secondary side of the CTs using the selected secondary CT’s. In Auto Mode, flexible CT or a multirange Clamp CT is used for the primary side measurement. Channel 4 is used for the primary CT.

The user selects the type of Primary CT being used and then clicks the button for the phase that the primary CT is connected to. The primary CT is then moved to the next phase and the corresponding button is clicked.
