Table of Contents Learn more about split core current transformer With the development of digital substations and smart grids, electrical current transformers have been widely used, mainly in the measurement, protection and monitoring of power systems. Current transformers are widely used to convert a high voltage current input and produce a proportional low voltage, low current signal…
Split core current transformers are often used in equipment and have excellent induction effects, which can improve the use efficiency of equipment, have a good effect in controlling current, and complete the conversion of upper and lower voltages. How should we fix it in order to make it work smoothly and avoid vibration? Xiamen ZTC…
The zero phase current transformer is a line fault current monitor. Generally, there is only one iron core and secondary winding. When using, the primary three core cable is passed through the iron core window of the transformer, and the secondary wire is connected to a special relay, and then the output terminal of the…
Current transformer selection points (1) The rated frequency of the current transformer should be consistent with the current frequency of the line under test. (2) Select the rated voltage of the current transformer according to the voltage level of the line under test to ensure the safety of the staff and the instrument. Never use a current…
Electronic current transformers are based on Rogowski coils with small size, light weight, wide frequency band, factors that more or less affect the accuracy of the coil in the measurement operation, such as the size of the circuit conductor under test relative to the coil, and external electromagnetic interference. , The circuit under test has…
1)The wiring of the current transformer should follow the series principle: the primary winding should be connected in series with the circuit under test, while the secondary winding should be connected in series with all loadded instruments. 2)Selecting appropriate transformation ratio according to the measured current, otherwise the error will be larger. At the same time, one side of the…
