The lifespan assessment and maintenance planning of high-voltage power systems requires
condition monitoring of all the operational equipment in a specific area. Electrical insulation …

Due to the expansion of high-voltage direct current (HVDC) power systems, manufacturers
of high-voltage (HV) hardware for alternating current (ac) applications are focusing their …

The localization of emitters using an array of sensors or antennas is a prevalent issue
approached in several applications. There exist different techniques for source localization …

This paper discusses the application of the first peak and cumulative energy methods to
calculate the time difference of arrival (TDOA) of UHF signals emitted by a partial discharge …

The paper reports on the solution, principles, and application results related to a system for
diagnosing main transformers in power plants via the radiofrequency method. The subject of …

This paper proposes a method to localize multiple partial discharge (PD) sources in air-
insulated substation by using radio frequency (RF) antenna sensors combining with …

Monitoring of partial discharge (PD) activity within high-voltage electrical environments is
increasingly used for the assessment of insulation condition. Traditional measurement …

Partial discharges (PDs) are symptomatic of some localised defects in the insulation system
of electrical equipment. PD activity emits electrical pulses in the form of radio frequency (RF) …

Partial discharge is a well-established metric for condition assessment of high-voltage plant
equipment. Traditional techniques for partial discharge detection involve physical …

The measurement of the emitted electromagnetic energy in the UHF region of the spectrum
allows the detection of partial discharges and, thus, the on-line monitoring of the condition of …
