Smart grid construction drives current sensor technology development

With the continuous development and upgrading of smart grids, current sensors are constantly improving and improving in terms of technology, design, and utility, and have a major effect on current measurement in multiple industries.

Take the fiber-optic current sensor as an example, China has introduced the XDGDL-1 fiber-optic current sensing system, which realizes all-digital closed-loop control of the pipeline current sensing system, which is characterized by good stability, linearity, and high sensitivity, and it satisfies a large range of requirements. High-precision measurement requirements.

At the same time, the system has developed a telescopic structure that can be wound in the field. It is easy to install and can avoid the interference of stray magnetic fields. The measurement error of the bus eccentricity is less than plus or minus 0.1%, and a high-precision signal conversion scheme is realized for the rectifier. Control equipment provides high-precision analog signals and standard digital communication interfaces.

With the construction of smart grids, the requirements for current sensors are getting higher and higher. The current sensors must be improved in sensitivity, stability, and other aspects in the future. They must be more sensitive, more robust, and less disturbing. The development of power consumption, smarter design, miniaturization, integration, and improvement of temperature stability, better serve smart grid construction and upgrades.
