Remarks:
a.In practical applications, the sampling resistor should be smaller than or equal
to the rated value given in table above in order to improve the non-linearity
and phase shift.
b.We can have it customer-made if required current ratio is not listed in the
table above.
8.Attention:
- The primary of the current transformer must be connected in series with the
loop of the measured current. The secondary should operate in a mode of near short
circuit.
- The secondary of the current transformer is not allowed to be open circuit,
Do Not install any fuse.
