Interdigital Capacitive Sensor for Cable Insulation Defect Detection: Three-Dimensional Modeling, Design, and Experimental Test

Figure 14

Measured capacitance difference and simulated capacitance difference between the normal and defective cable joints: “6-1 experiment” means the measured capacitance difference of the “6-1” sensor and “6-1 simulation” means the simulated capacitance difference of the “6-1” sensor.
