Description

This is non-invasive CT (Current Transformer) sensor, based on the magnetive transomfer working principle, which is hard to be explained by us but you can read a lot on this current transformer wiki page, or similar device “current clamp”. If you are interesting on power energy measurement, power grid, or measuring any alive domestic appliance or your system, this is one thing fun to try.

Applications

  • Suitable for the current measuring
  • Monitoring and protection of AC motor
