High-voltage Reactive Power Compensation Controller
Product Description:
The high-voltage reactive power compensation controller uses a 32-bit ARM microprocessor chip and a multi-tasking operating system kernel. Mass storage, AC sampling technology, LCD Chinese display, four-quadrant analysis and other technologies have realized real-time data acquisition, communication, historical data storage, fault alarm, power grid harmonic analysis, reactive power compensation and other functions, mainly used in high-voltage distribution networks, Monitor the operation status of distribution transformers and distribution lines and compensate grid reactive power, and automatically control capacitor switching to compensate according to the size of reactive power, power factor and voltage range, effectively improving the quality of power supply voltage and the safety of the distribution network Level of stability and economic operation. This product is a perfect combination with mechanical products, which effectively prolongs the service life of mechanical products, and the products have passed the inspection of the Quality Inspection Center of Reactive Compensation Units of the Ministry of Power Industry.
Product Features:
