| Abstract: | Aiming at the shortage of measuring mechanism for electrical equipment fault caused by dielectric in current electrical power system, the authors analyze the measurement theory for dielectric loss, propose an on-line measurement system for dielectric loss based on the single chip, and use LMS adaptive filtering algorithm in the design system. It is proved that the algorithm can greatly reduce the errors and improve the measuring accuracy compared with the traditional method. The measuring system has the advantages of good stability and reliability as well as easy adjustment. |
