According to the term definition in the standard "Electric Energy Metering Cabinet" (GB / T 16934-2013), an electric energy metering cabinet is a dedicated cabinet type of electric energy metering device (electric energy metering device). An electric energy metering device is a general term for the combination of all electrical equipment, electrical parts and mechanical structures for measuring electric energy.
[0003] A current transformer is an instrument that measures by converting a large current on the primary side into a small current on the secondary side based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series in the circuit where the current to be measured is located.
