What should I pay attention to when applying a transformer?

1, the rated primary current of the current transformer is generally 1.2 ~ 1.4 times the line current selection of current transformers, which is mainly to consider the line overload does not burn the current transformer and ammeter or meter and other electrical equipment.

　　
2, the rated primary current of the current transformer can not be selected than the actual working current of the line is too large a difference, which will affect the accuracy of the measurement of the current transformer.

　　
3, the transformer is in the rated secondary output load range to ensure the accuracy of the transformer. Therefore, including the secondary line load and metering device load for the actual load of the transformer, when the actual output load of the secondary transformer is greater than the rated output load of the secondary transformer, the accuracy of the transformer will be reduced, and severe overload will burn the transformer.

　　
4, when the actual output load of the secondary transformer is lower than the rated secondary output load of the transformer, the accuracy of the transformer will be reduced.

　　
5, as noted in the different occasions for the use of suitable transformer products.

　　
6, outdoor transformers and indoor transformers do not mix.
