Stability and wide application of ground fault zero-sequence current sensor

- May 28, 2019-

The ground fault zero-sequence current sensor has high sensitivity when used, and the intensity of the detected signal becomes weaker and weaker, which requires the sensitivity of the magnetic sensor to be greatly improved. Applications include current sensors, angle sensors, gear sensors, and space environment measurements.

The temperature stability of the ground fault zero-sequence current sensor, more applications require the sensor to work more and more harsh, which requires the magnetic sensor must have good temperature stability, industrial applications include the automotive electronics industry.

Ground fault zero-sequence current sensor immunity. In many fields, there is no comparison of the sensor environment, and the sensor itself is required to have good anti-interference. Including automotive electronics, water meters and more.

Miniaturization, integration, and intelligence of ground fault zero-sequence current sensors. To achieve the above requirements, this requires chip-level integration, module-level integration, and product-level integration. 5. High frequency characteristics. With the promotion of the application field, the working frequency of the sensor is required to be higher and higher, and the application fields include the water meter, the automobile electronics industry, and the information recording industry.

Low power consumption of ground fault zero sequence current sensor. Many areas require the sensor itself to have very low power consumption to extend the life of the sensor. Applied to magnetic biochips, compasses, etc. implanted in the
