Condition assessment of Medium Voltage switchgears requires effective, but inexpensive
solutions to become a common practice. On the other hand, failure of a switchgear …

Measuring partial discharges in DC insulation systems is an issue due to the lack of a
reference relating the voltage waveform to the physics of discharge phenomena. Also, DC is …

Condition monitoring and maintenance in rotating machine are generally managed through
expert evaluation of the diagnostic properties and relevant harmfulness of the underlying …

The design and operation of DC insulation systems is more complex than for AC sinusoidal
supply. The most subtle issues are how the electric field in DC can vary with operation and …

Failure of underground cables due to high degradation-rate phenomena, as partial
discharges followed by electrical treeing, is one of the major causes of cable outages …

This work proposes a methodology for noise removal, separation, and classification of
partial discharges in electrical system assets. Partial discharge analysis is an essential …

Medium Voltage (MV) electrical assets are no longer just distribution networks, since also
electrified transportation is moving towards kV, if not tens on kV, of target operating voltage …

Laminated busbars, LBB, can be a competitive component to improve effectiveness of
electrical assets on ships, but there is not too much experience yet about accelerated aging …

This paper has a twofold aim. On one side, it aims to show a paramount application of an
innovative approach to automatic partial discharge (PD) monitoring and analysis, referring to …

Quality control, commissioning and operation of DC cable systems (and, in general,
electrical apparatus) require PD testing and monitoring technologies that are effective in …
