Brief Introduction of Rogowski Coils, from Three Aspects
Jun 17 , 2022
What is the Rogowski coil? The Rogowski coil is a flexible clip-on hybrid inductor coil that can be easily coiled around a current conductor for measuring. It is capable of measuring large currents of several thousand amperes without expanding the size of the voltage transformer. Rogowski coils are electronic voltage transformers used to measure alternating currents such as fast transients, single...

Three main parameters that interfere with the accuracy of Rogowski coils
Jun 18 , 2022
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 the advantages of large conductor volume range, no ma...

Current transformer selection points
Jul 19 , 2022
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 transformer with a lower rated voltage to measure line ...

Can current transformers be used for high voltage applications?
Jun 06 , 2023
Current transformers are primarily designed for measuring and monitoring electrical currents in various applications. However, their usage can be extended to high voltage applications when used in conjunction with voltage transformers. In high voltage systems, measuring the current directly can be challenging and unsafe due to the high voltages involved. Therefore, current transformers are employe...
