           Cautions of Current Transformer:

             1. Suggestions of choosing (Take ct for energy meter as an  example)
            (1)Please offer the primary current and secondary current or primary current and ratio as per your requirements.
            For example, if the energy meter is 5(80)A, you may need a current transformer with a current of 80A or 100A.

            (2)Please specify the accuracy as per the secondary circuit or accuracy requirements of the energy meter.
            For example, If it's an industrial degree meter then you may need a high accuracy current transformer such as Class 0.5S, Class 0.01/0.02.
            (3)Customized terminal design for your primary circuit - if it's not good for fixing or you need to integrate with
            relay/shunt/terminal block etc then you may need to offer your drawing for design and adapt to the application.
            (4)Plz choose the suitable secondary output terminal, if you need to solder and fix it on PCB then you may need to
            choose PCB/pin type, for other situations, you can use lead wires directly.

 

            2. Standard of good current transformer
            (1)Plastic casing instead of traditional tape which is anti-dust, anti-shock,anti-flaming for security.

            (2) A central rubber hole is more flexible for installation.

            (3)Moreover current transformers become advanced and smart, hence 500mT permanent magnetic immunity,
            high accuracy when cosφ=0.5, and smart CT with M-bus or RS485 communication are welcomed as well.
