摘要

In this work, we use a capacitance sensing technology to design an online monitoring system for power lines. By the theoretical analysis and simulation of a plurality of coplanar metal line electrode fields and capacitors, as well as the freezing tests of the system in low temperature, the system could be powerful for monitoring the ice thickness of power lines. We found out that the capacitance can be formed due to the metal electrode changes if the sensor is merged into ice coatings of analog conductors. Especially, the system possesses a simple structure, high accuracy, readily installation, and low costs.
