Dependence of Long-term Dielectric properties of Crosslinked Polyethylene Insulated Cable on High Harmonic Voltage

摘要

For the linear synchronous motor (LSM) type superconducting MAGLEV system, a pulse width modulation (PWM) inverter has been developed. The output voltage with a large quantity of harmonics generated by the PWM inverter is loaded onto crosslinked polyethylene insulated cables (CV cables). The dielectric strength of CV cable under the voltage containing harmonics has never been reported so far.
