Identifying harmonic attributes from online partial discharge data

, 2011
Partial discharge (PD) monitoring is a key method of tracking fault progression and degradation of insulation systems. Recent research discovered that the harmonic regime experienced by the plant also affects the PD pattern, questioning the conclusions ...

Blind equalization of partial discharge channels [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla"
In the case of partial discharge signals, obtained during "online" monitoring or "off-line" tests of the generator, there is often interference between the direct and reflected signals or disturbances during propagation through the medium, i.e.
