Introduction:
Split core current transformers are a series of miniaturized openable products designed based on the improvement of current instrument and equipment software processing capabilities. Due to the increase in current monitoring equipment, a small and easy-to-install split core current transformer is needed. This type of product generally uses a small current signal output or a voltage signal output to maximize product accuracy and reduce hardware costs. Standard 5A or 1A current output products have poor load capacity, and it is recommended to use a wire with a cross-sectional area of not less than 2.5mm2. When outputting current signals, the secondary circuit of the transformer needs to be connected before installation to avoid the risk of electric shock due to high voltage generated by the open secondary circuit during installation. After installation, the transformer needs to be well fixed on the measured wire with a nylon tie. This series of product designs can use silicon steel cores, nanocrystalline alloy cores, ferrite cores, etc. according to needs, and reduce costs as much as possible while ensuring application.
