A symmetrical layout with the CT2002-2 at the center, and a solid ground plane on the bottom layer, is recommended. This helps to minimize electromagnetic interference and ensures optimal performance.
To ensure accurate current measurement, use a burden resistor with a low tolerance (e.g., 1%), and ensure the CT2002-2 is properly calibrated. Additionally, minimize noise and interference by using a shielded cable and keeping the CT2002-2 away from high-voltage sources.
The CT2002-2 can operate within a temperature range of -40°C to 85°C. However, it's recommended to operate within a temperature range of 0°C to 70°C for optimal performance and accuracy.
The CT2002-2 is designed for low-frequency current measurement (up to 100 kHz). For high-frequency current measurement, a different current transformer with a higher bandwidth is recommended.
Use a fuse or a current limiter in series with the CT2002-2 to protect it from overcurrent. Additionally, use a voltage limiter or a surge protector to protect the CT2002-2 from overvoltage.
