摘要：
A transmission line ice thickness real-time simulation and online monitoring system were designed by using the coplanar multi-point capacitance sensor technology. The capacitance sensing type ice thickness sensor is used in the system to detect the metal electrode capacitance change on various positions surrounding the analog transmission line, and verify the ice thickness on analog line. By theoretical analysis and simulation of a plurality of coplanar metal line electrode fields and capacitors, as well as the freezing test of the system in low temperature, the system is validated to have the feasibility of monitoring the ice thickness of transmission lines.
