AC Current Sensing Technology

It improves both intrinsic errors in low current and errors occurred by external vibration and shock with strong durability and minimum tolerance on cutting cross section of core. Main applications are sub-metering, power meter, PLC(Programmable Logic Controller), energy automation and etc.

Measuring Principle

The core placed around the current bus is provided with a secondary winding(N turn), in which electromagnetic induction caused by AC electricity to be detected (I) induces secondary current (I/N).

The core material of J&D AC CT is saturated by the over current owing to the conductor, the linearity of secondary output current will be distorted and or the error of phase angle will be caused.

Before using of J&D AC CT, please refer to the data sheet.
J&D recommends the best solution from our AC CTs for your measuring applications.
