7. Typical Application and Performance Parameters:

See the table below for performance parameters in typical applications as shown in Figure 3 on the right:

Note: This series of transformers is used for zero-sequence current protection. It is designed with a shielding layer. The length of the output lead can be customized according to customer requirements .

● Notes:

a. In practical applications, the sampling resistance should be less than or equal to the rated value given in the above table, which will improve the nonlinearity and phase shift;

b. If the conversion ratio required by the user is different from the above, it can be customized according to the user's requirements.

8. Attention:

① The primary of the current transformer should be connected in series with the circuit being measured, and the secondary should work close to a short circuit condition.

② The secondary circuit of the current transformer should not be open-circuited. Therefore, please do not install fuses.
