What aspects should be paid attention to when applying transformers?
Apr 19, 2023| 1. The rated primary current of the current transformer is generally selected according to the current of 1.2~1.4 times of the line. This is mainly to consider that the electric equipment such as the current transformer and the ammeter or the electric energy meter will not be burned when the line is overloaded.
2. The rated primary current of the current transformer cannot be selected too much different from the actual working current of the line, which will affect the measurement accuracy of the current transformer.
3. The accuracy of the transformer can only be guaranteed within the rated secondary output load range.
4. When the secondary actual output load of the transformer is lower than the rated secondary output load of the transformer, the accuracy of the transformer will decrease.
5. Select suitable transformer products according to different usage occasions.
6. Outdoor transformers and indoor transformers should not be mixed.
