Condition monitoring of an operating apparatus is essential for lifespan assessment and
maintenance planning in a power system. Electrical insulation is a critical aspect to be …

One of the most common failures or breakdowns that can occur in high-voltage (HV)
equipment is due to partial discharges (PDs). This occurs as a result of inadequate …

In this article, we have performed a comprehensive investigation in the specialty of ultra-high
frequency (UHF) printable antennas for partial discharge (PD) diagnostics. Due to the …

Monitoring the partial discharge (PD) activity of power equipment insulation is crucial to
ensure uninterrupted power system operation. PD occurrence is highly correlated to …

A new, bio-inspired printed monopole antenna (PMA) model is applied to monitor partial
discharge (PD) activity in high voltage insulating systems. An optimized sensor was …

In this article, it is provided a comprehensive survey on the most relevant research in the
area of detection, classification and location of partial discharge (PD) sources using the …

In this paper, the design and development of a bio-inspired UHF sensor for partial discharge
detection in power transformers is presented. The UHF sensor was developed for external …

The adaptation of dielectric windows as metamaterial superstrate over a bio-inspired Printed
Monopole Antenna (PMA) was evaluated in order to improve the detection sensitivity of Ultra …

Partial discharge (PD) is a symptom of insulation defect or degradation in high-voltage
power equipment. To detect the occurrence of PDs inside oil-filled power transformers, the …

In this article, simplified geometries for microstrip antennas were evaluated and optimized, to
select one appropriate geometry, aiming for its application of partial discharge (PD) …
