Current transformer is mainly composed of a primary winding,a secondary winding and an iron core, and there is insulation among the primary, secondary and iron cores. In order to improve the accuracy of the current transformer, the error of the current transformer is generally compensated.In addition to the above-mentioned primary and secondary windings and cores,…
The current transformer is very similar to the transformer. The transformer is mainly used to change the voltage of the line on the line, while the current transformer is mainly used to change the current of the line. Why do we need variable current on the line? This is because according to the different conditions…
This content discusses the importance of low-voltage current transformers and electric energy meters, emphasizing the need for DC Immune components in low-voltage electric energy metering devices. Non-linear loads and DC equipment pose challenges, making detection devices crucial.
PCT842 DC Immune Current Transformer Electrical Specification Rated Primary Current 100A Max Primary Current 210A Rated Secondary Current 100mA Accuracy 0.1~2.0 Electrical Strength 3000VAC 1mA60s Load Resistance 100Ω Rated Frequency 50/60HZ DC immune transformers are used to detect AC currents in the presence of DC bias. Current transformers can generate voltages as the current flows. They are primarily used to detect AC currents in circuits,…
