AI Technical Summary

Benefits of technology

This new method described in this patented allows for faster and easier analysis of electrical equipment's health condition based on its own characteristics such as temperature or pressure levels during use. By applying lasers onto specific areas of an electric device without any extra steps like separating gases before testing it, these methods are able to identify potential issues early enough that they may have already been damaged. Additionally, there exist various techniques used to reduce redundancy in spectral datasets obtained from different measurements made over multiple periods of observation (such as Fourier Transform) resulting in better overall performance compared to previous models. Overall, this innovation provides technical benefits including quick and precise diagnoses of power failings, increased recognition rates through advanced machine learning algorithms, reduced complexity due to fewer featured layers, enhanced reliability, etc., making them ideal tools for identifying important components within large complex systems containing many interconnected parts.

Problems solved by technology

The technical problem addressed in this patents relates to identifying faulty or damaged transformers during maintenance operations without human error while ensuring proper functioning of electric grids. Current solutions involve manually inspecting each unit individually, leading to delayed diagnoses due to fatigue and lack reliability. There have been attempts at developing faster and better ways to monitor these assets safely before they fail catastrophically.
