Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surge protection devices (SPDs) are inadequate in responding to the rapid and complex electromagnetic pulses from natural and technology-based sources, such as high-altitude nuclear EMP, intentional electromagnetic interference, and geomagnetic disturbances, leading to potential damage to electrical and electronic systems due to their limited response time and energy handling capacity, which degrades over time and usage.
Innovation Solution
The implementation of a system and method for real-time monitoring and displaying the operational status of SPDs, utilizing a combination of components like transient voltage suppressors, metal oxide varistors, and gas discharge tubes, designed to withstand high voltage and current transients, with hybrid approaches and distributed metamaterials to provide enhanced protection and resilience, including continuous monitoring and cybersecure remote notification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surge protection devices are designed to withstand high voltage and current transients from EMP and other electromagnetic surges, then protection capability is improved, but response time and energy handling capacity are limited and degrade over time
Solution Approach 1:
The system performs preliminary monitoring of SPD operational status through continuous electrical characteristic measurement. By detecting degradation trends before failure occurs, the system enables preventive maintenance actions that restore SPD effectiveness, ensuring response capability is maintained without waiting for actual surge events
Solution Approach 2:
The system continuously monitors electrical characteristics (voltage, current, resistance) of SPD components and provides real-time feedback on their operational status. This feedback mechanism detects degradation in response time and energy handling capacity, allowing for timely maintenance intervention to restore full protection capability
2Reliability
If surge protection devices are designed with higher energy handling capacity to withstand intense electromagnetic surges, then protection effectiveness is improved, but device complexity and cost increase
Solution Approach 1:
The SPD system is divided into multiple monitorable components (varistors, gas discharge tubes, TVS diodes) with individual status tracking. The monitoring system segments the overall protection function into discrete electrical characteristics that can be measured and evaluated separately, simplifying the management of complex multi-component SPD systems
Solution Approach 2:
The monitoring system acts as an intermediary between the complex SPD components and the user/maintenance personnel. By measuring electrical characteristics and translating them into operational status indicators, the system simplifies the assessment of multi-component SPD effectiveness without requiring direct analysis of each component's complex behavior
3Loss of time
If continuous monitoring of SPD operational status is implemented, then preventive maintenance capability is improved, but system complexity and power consumption increase
Solution Approach 1:
The monitoring system utilizes the SPD's own operational electrical characteristics (voltage, current, resistance) as the monitoring signal source. By measuring parameters that naturally exist during SPD operation, the system achieves self-monitoring without requiring external power sources or additional sensing infrastructure, minimizing power consumption while enabling continuous status assessment

AI summary
A method and system for status monitoring of transient surge protection devices may display operational status and instantaneously a fault condition of a surge protection device (SPD) induced by transient electromagnetic energy disturbance from high altitude nuclear weapon detonation generating an electromagnetic pulse (EMP), Geo-magnetic disturbance (GMD), solar corona mass ejection (CME), intentional electromagnetic interference (IEMI), natural lightning strikes, or other transient surges due to radiated and conducted EMI. The system monitors operational status and readiness of SPDs installed on electric power networks to protect devices powered by the networks. The status monitoring of SPD has local display and cybersecure, over-the-power-lines communication (OPLC), implemented with analog circuits and instantaneous response. The system comprises embedded self-testing and diagnosis of surge protection assemblies with test data collection and ML/AI algorithms for preventive maintenance of distributed SPDs, protecting AC and DC installations on primary power distribution networks, mini grids, and backup power systems.
