“…In their work, Amorim Jr. et al [67] used a high-frequency current transformer (HFCT) sensor for online monitoring of partial discharges. Another work addressing the use of HFCT is presented by Tatizawa et al in [68]. As observed for temperature and current monitoring techniques, methodologies combining PD and leakage current monitoring appear in the literature.…”

This paper presents a literature review on the subject of Condition-Based Maintenance of surge arresters. Both a bibliometric analysis and traditional comprehensive research are presented. The bibliometric analysis is useful for obtaining insights about the literature. It quantitatively highlights relationships between journals, authors and keywords (related to the monitoring methods) and reveals future trends for research based on the timeline of the keywords. The traditional comprehensive literature review is also presented. It summarizes the methods, their advantages and disadvantages and also points to some known measurement issues of the methods. Both online (leakage current, harmonic components, temperature, partial discharges, power loss and the counting of discharges) and offline (reference voltage, residual voltage, insulation resistance, polarization/depolarization, return voltage, microscopy, spectrometry, X-ray, RUS and the recent application of FRA) methods have been qualitatively analyzed.

“…As an alternative to the above online methods, one can highlight the methods which use the monitoring of partial discharges. According to [ 17 ], partial discharges can be measured based on electrical variables (such as current pulses measured with a high frequency current transformer [ 18 ]) or as non-electrical variables (such as sound [ 19 ], light [ 20 ] and electromagnetic waves [ 21 ]).…”

This work presents an innovative application of Frequency Response Analysis (FRA) in order to detect early degradation of Metal Oxide Surge Arresters (MOSAs). This technique has been widely used in power transformers, but has never been applied to MOSAs. It consists in comparisons of spectra, measured at different instants of the lifetime of the arrester. Differences between these spectra are an indicator that some electrical properties of the arrester have changed. An incremental deterioration test has been performed on arrester samples (with controlled circulation of leakage current, which increases the energy dissipation over the device), and the FRA spectra correctly identified the progression of damage. Although preliminary, the FRA results seemed promising, and it is expected that this technology could be used as another diagnostic tool for arresters.
