AI Technical Summary

Benefits of technology

This patented technology allows for accurate measurements on AC power systems without being affected by external factors like temperature or humidity changes over time. Its technical effect includes improved control capabilities during faults caused by abnormal voltage levels or currents flowing through them while also providing better overall monitoring functionality.

Problems solved by technology

This patented describes different ways to connect and use optically measurable measurements to quickly verify the function and reliance of certain types of industrial optics such as flexible direct current transfer (FDCT). These techniques involve connecting opticals called optoelectronic modules together at specific points along its length without disconnecting any other components during testing. However, these conventional open loop simulations lack accuracy when analyzed accurately compared to modern digital tools like Optical Current Transform (OCC), allowing potential issues related to instabilities caused by external factors affecting the connection between the module's photocoupler terminals.
