The effect of DC bias on electrical tree growth and partial discharge (PD) characteristics in
epoxy resin (Araldite LY® 5052/Aradur® HY 5052 supplied by Huntsman) is investigated …

Typically, in laboratory and diagnostics tests focused on measuring partial discharges, a
pure sinusoidal voltage waveform is assumed. However, in practice the spectral content of …

Voltage harmonics are present in various forms and compositions in both power distribution
and transmission systems as well as in an industrial environment. This paper presents the …

Typically, in partial discharges (PD) diagnostics tests carried out in a laboratory, harmonic
content in a voltage waveform is ignored. However, during the operation of variable …

Electrical tree in silicone rubber (SiR) is a threat to the power system. Bedsides ac and dc
voltage, there are pulse voltage in power system and the electrical tree behavior in SiR …

The shape of electrical trees gets altered due to applied voltage profile. Bush type electrical
trees forms under harmonic voltages with lower THDs. With increase in harmonic level with …

In this paper, the effects of harmonic superimposed DC voltage on electrical tree growth
characteristics in ethylene propylene diene monomer (EPDM) for HVDC cable accessories …

HVDC converters can generate harmonic voltage, which distorts the DC voltage quality and
