Benefits of technology

This patented technology helps prevent damage from overheating or other electrical equipment due to repetitive electricity discharges between two conductors. By analyzing various types of arc modelled data with an algorithm called SEM (Simulation Programming), it becomes possible to determine how much energy was being released at each point on this circuit's surface without rebuilding any new circuits after every occurrence of these events. Overall, this system provides technical benefits such as reducing maintenance costs while maintaining reliable performance levels.

Problems solved by technology

This patented technical problem addressed in this patents relates to analyzing the effects caused by various factors such as pantographic-cord loop unbalance (PCC), uneven distribution of power supply between tracks, insulation breakdowns due to eletrostatic discharge, etc., which may lead to damage and potential safety hazards for trains operating at higher speeds under stress conditions. Current methods involve measuring these variables manually with tools like calipers or scanning optical images, resulting in time delays and lack accuracy.
