With the continuous advancement of technology and the vigorous promotion of smart grids in China, the demand for current sensors in the market is expanding. With the increase of urban electricity consumption, traditional current measurement methods are no longer able to meet the current electricity situation. Therefore, new types of current sensors PCB sensors will be applied. In order to achieve the desired working state of the drive, it is necessary to continuously measure the current during operation. The performance of the current sensor directly affects the quality and response time of the circuit control, which is also the reason why it can be widely used in the wind power industry.
In the converter, it is necessary to install a large number of small or PCB current sensors, which belong to a closed-loop control system to ensure that the inverter can respond quickly. The simultaneous action of the inverter and generator ensures continuous power supply to the grid over a wide range of wind speeds after the wind turbine is started, until the turbine shuts down at the upper limit wind speed.
With the continuous development and upgrading of smart grids, current sensors are constantly being improved and perfected in terms of technology, design, and utility, playing a significant role in current measurement in industries such as metallurgy and chemical engineering.
