Non-Intrusive Voltage-Inversion Measurement Method for Overhead Transmission Lines Based on Near-End Electric-Field Integration

Existing electric-field integral inversion methods have limited field application conditions, and they are difficult to arrange measurement points on high-span overhead lines. This paper proposes a non-intrusive voltage method for transmission lines based the near-end integration method. First, distribution under 10 kV is calculated by finite element simulation software. The of plumb line discrete node below wire analyzed. Then, traditional integration, line-voltage-inversion proposed. In addition, voltage-monitoring system constructed. Next, numerical types, number nodes, scale coefficient region algorithm optimized with data. Finally, verify voltage-inversion proposed in this paper, test platform overhead-line constructed using MEMS sensor. results indicate that error 5.75%. research will provide theoretical guidance
