Benefits of technology

This technology helps prevent damage caused from leaks that may occur during use or when there are no electrical connections between two devices connected through wires. It uses an inspection system with multiple lines for accurate voltage measurements over time to determine if any problems have occurred due to these issues.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the functionality of electronic devices used on power lines such as AC plugs. These devices may experience arcing faults due to exposure to high voltage levels during use. To address these issues, various solutions were developed including adding extra components like resistors to isolate specific parts within the device's signal path. However, it was found that some leaks still occur despite these measures being effective.
