Current transformer output current 5A
-
Current transformer measuring range 200A 1 ~ 10000A
If an Smart Energy Meter equipped with external current transformer is
applied, the measurement range (primary current) of the current transformer
should be selected according to actual maximum current at the grid-
connected point, and the maximum secondary current (output current) of the
current transformer should be 5A.
The current transformer’s primary current should be equal to or greater than
the maximum expected AC current from the grid, per phase. Important: The
closer the expected AC current is to the chosen primary current value, the
more precise the measurement will be.
