Analysis of Several Typical AC Power Cable Crosstalk Simulation Tests

Abstract

Based on the cable transmission line simulation method, this paper conducts cable string simulation analysis on common power signals, including: 115V 400Hz single-phase AC, 220V 50Hz single-phase AC, 380V 50Hz three-phase Y-type AC power. Meanwhile, through the programmable power supply, using the electric furnace as the load, the coupled voltage waveform on the cable under test is measured by an oscilloscope. Through the simulation and test methods, the crosstalk of several typical AC power lines to adjacent bare wires is analyzed. By changing the parameters such as cable spacing, cable length, the interference signal, the influence of the above parameters on the crosstalk of the power cable was studied, and the relevant research conclusions were formed. The comparison simulation and the measured results showed that the trend was basically the same. Conclusions about the power cable crosstalk in this paper can provide theoretical support for more deeply crosstalk research about other kinds of cables, such as communication cables, signal cables. Moreover, these conclusions can also offer useful suggestions to complex cable layout in practical projects.
