Q: What are the main parameters of the CT?
A: These parameters include installation mode, aperture size, current specification, and current convert ratio.
Q: What safety matters should pay attention to when using the CT?
A: Wiring must comply with specifications, especially secondary can not be opened.
Q: Is it important to choose the matching rated current of the transformer for the ac meter?
A: Yes. The CT with appropriate rated current should be selected according to the range of the actual current, otherwise the measurement error will be caused.
Q: Is the connection direction of CT important in the connection operation?
A: The direction of the wiring is important, or it may lead to measurement errors or confusion.
