Conditioning Mechanism of Cu-Cr Electrode Based on Electrode Surface State under Impulse Voltage Application in Vacuum [PDF]

, 2011
Because of high insulation performance and environmental-friendliness, vacuum is attracting considerable attention, and vacuum circuit breakers (VCBs) are expected to develop into higher voltage level.

Partial discharge characteristics of insulation used in inverter-fed traction motor under high frequency impulse [PDF]

, 2012
Stator insulation in inverter-fed traction motors may prematurely lose its function due to continuous square impulses voltage of converters, whose insulation failure mechanism is different from that under power frequency AC voltage. Partial discharge (PD)

Characteristic impulse-response grammians

Electronics Letters, 1991
A new Grammian known as the characteristic impulseresponse Grammian is introduced. It is an extension of the impulse-response Grammian presented by Agathoklis and Srceram. An important property of the characteristic impulse-response Grammian which can be useful in modelreduction application is also derived.

Impulse Characteristics of Ground Electrodes in Low Resistivity Soil [PDF]

, 2023
Soil properties have been known to be the factors that influence the ionization process in soil, which cause the impulse impedance, Zimpulse to be lower than that at steady state resistance, RDC. Many studies have established the relationship between the

Electrical Tree Initiation Properties in Cross-Linked Polyethylene Under DC-Impulse Composite Voltages

IEEE Access, 2018
DC cables may be subjected to impulse overvoltage during operation, which may cause electrical tree inside the cable insulation. So, it is necessary to investigate the influence of impulse voltage on the insulation of dc cable.
