How to choose Electrical Current Transformer?

(1) The rated primary current should be within the range of 20% to 120% of the operating current.

(2) The rated primary voltage of the Electrical Current Transformer is the same as the operating voltage.

(3) Make sure that the power consumed by the secondary side load does not exceed the rated capacity of the Electrical Current Transformer, otherwise the accuracy of the Electrical Current Transformer will decrease.

(4) According to the power supply mode of the system, choose the number of Electrical Current Transformer units and different wiring methods.

(5) According to the purpose of the measurement and the requirements of the protection method, select the accuracy level of the Electrical Current Transformer.
