Hop anti-magnetic DC single phase micro electronic current transformer 400/5 with current insert smart meter CT
This product is suitable for electric energy measuring instruments and meters; electric parameters transducer;Telemetry remote control data acquisition system;Relay protection systems.Normally,the secondary current is s proportional to the first input current, and the phase difference is close to zero when the connection method is correct.
Features & Advantages
1. The shell is made of high reliable flame retardant material to prevent high temperature aging.
2. Ingenious terminal design, to avoid the leakage of terminal, both safe and beautiful.
3. Using special magnetic core material, pure copper wire winding system, more stable performance, good product consistency.
4. Electrical strength: o breakdown, arc flying and dizziness (leakage current 1mA) between primary winding and secondary winding in 3kV, 50Hz and 60s.
5. Insulation resistance: ≥1000M between primary winding and secondary winding (DC500V)

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.
