Influence of frequency on the surface discharge characteristics of PEEK under positive repetitive square voltage

Influence of frequency on the surface discharge characteristics of PEEK under positive repetitive square voltage

In this study, the surface discharge current pulses of polyetheretherketone (PEEK) material under positive repetitive square voltage in a nitrogen atmosphere are measured. The influences of different voltage amplitudes and frequencies on the detail parameters of forward discharge and backward discha...
