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...

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...
