In this paper, a non-invasive electromagnetic method using free-space transmission measurements with patch antennas is presented as a promising approach for real-time detection of dielectric property variations induced by oil aging. This measurement technique eliminates the need to extract oil samples and transport them to a laboratory for chemical analysis, allowing the oil condition to be assessed directly in situ. As such, it represents a significant advancement toward the development of smart, integrated oil condition monitoring systems for industrial and energy infrastructures.

摘要

In this paper, a non-invasive electromagnetic method using free-space transmission measurements with patch antennas is presented as a promising approach for real-time detection of dielectric property variations induced by oil aging. This measurement technique eliminates the need to extract oil samples and transport them to a laboratory for chemical analysis, allowing the oil condition to be assessed directly in situ. As such, it represents a significant advancement toward the development of smart, integrated oil condition monitoring systems for industrial and energy infrastructures.
