1.1 Historical development of Ultracapacitor Ultracapacitor first appeared in the middle of the 18th century. Pieter Van Musschenbrock of Leiden University in the Netherlands and Ewald Geory Von Kleist of Germany developed the Leiden bottle, which is recognized as the prototype of all capacitors. In 1879, Hermann Ludwig Ferdinand Von Helmholtz discovered the interface double electric [...]
✨Metal oxide (hydroxide) is currently the material with the highest specific capacitance and energy density. In addition, it has the advantages of rich raw materials, diverse morphology and structure, low resistance and high power density, and has become the recognized preferred material for supercapacitor electrodes. 🌟The supercapacitor with metal oxide as electrode material belongs to Faraday [...]

1 Precautions for the operation and maintenance of filter and shunt capacitor devices 1.1 Monitoring of capacitor unbalanced current operation 🌟One of the most important functions of the AC filter and the shunt capacitor is to provide reactive power for the DC system. When the reactive power does not meet the absolute minimum filter (the absolute [...]
1. The Importance of Equipment Installation Tracking 💐The DC converter station usually shoulders the important task of interconnecting large-scale power grids and transmitting electric energy with high power. The safe and stable operation of a single station often determines the safe and stable operation of the large power grid system, and the safe and stable operation [...]
