Langmuir probe measurements of double-layers in a pulsed discharge [PDF]

Langmuir probe measurements were carried out which confirm the occurrence of double-layers in an argon positive column. Pulsing the discharge current permitted probe measurements to be performed in the presence of the double-layer. Supplementary evidence,

Transient overvoltage suppression of LCC‐HVDC sending‐end system based on DC current control optimisation

IET Energy Systems Integration
The receiving‐end system AC fault of the line‐commutated‐converter‐based high voltage direct current (LCC‐HVDC) will lead to commutation failure of the inverter side.
