    Ultra high frequency partial discharge sensors based on various microstrip patch antenna designs by Jaruman, S., Saman, N. M., Xiang, H. C., Ahmad, M. H., Buntat, Z., Adzis, Z.

    Published 2021
    “…The presence of PD activity is a warning indicator that the insulation deterioration would worsen over time, leading to catastrophic failure if the associated defects are not addressed early. Ultra-high frequency (UHF) has been proposed as a non-conventional method for detecting PD because of its resilience to external noise, high sensitivity, and online measurement potential. …”
