Innovation Summary:
This invention introduces a system for detecting and mitigating temporary overvoltage and ground fault overvoltage events in electric power systems. The method relies on real-time measurement and analysis of current flowing through surge arresters to identify abnormal voltage conditions. By analyzing the arrester current waveform, the system can distinguish between normal and fault conditions without requiring additional voltage sensors. This approach enhances grid reliability and safety while reducing hardware complexity.

Challenges / Opportunities:
Traditional overvoltage protection systems often depend on voltage sensors or rely on indirect indicators that may not provide timely or accurate fault detection. This invention addresses those limitations by using arrester current as a direct and reliable indicator of overvoltage events. It opens opportunities for smarter grid protection, especially in renewable energy systems and high-voltage transmission networks.

Key Benefits / Advantages:
✔ Real-time detection of overvoltage and ground fault events
✔ Eliminates need for dedicated voltage sensors
✔ Enhances grid safety and reliability
✔ Reduces system complexity and cost
✔ Applicable to both AC and DC power systems

Applications:
• High-voltage transmission and distribution networks
• Renewable energy systems (e.g., wind, solar)
• Smart grid protection and monitoring
• Industrial power systems
• Utility substations
