The broader/commercial impact of this Small Business Technology Transfer Phase I project seeks to develop an electronic partial discharge (PD) monitoring system that addresses the unmet need for noninvasive, cost-effective continuous PD monitoring. Over two-thirds of electrical transformers in the United States are at or past their expected lifespan, leaving the energy grid at risk of catastrophic failure. Current technologies for monitoring transformer health are expensive to operate, invasive, or require the use of additional resources (e.g., off-site analysis equipment). Because of the resources and human-power required of these existing tools, particularly those that require testing at the transformer site, PD monitoring occurs infrequently (i.e., annually) and only identifies PD after it has occurred. The technology to be developed offers risk mitigation by enabling electric companies to make informed decisions about transformer maintenance, utilizing PD detection and prediction capabilities. This technology will have unmatched value in strategic planning, where plans for transformer maintenance and replacement are based on continuous health information. Overall, the technology will positively impact all Americans that use electronics regularly, and could ultimately serve as a platform that can monitor PD in a variety of electrically insulated components, such as switchgears, inverters, generators, and electric motors. The intellectual merit of this project involves
