Voltage Surge Protection via Meteorological Data Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for protecting electrical installations from voltage surges caused by meteorological events, such as lightning, are unreliable as they often wait for the event to occur before disconnecting from the network, leading to potential damage to the installation.
Innovation Solution
A method that connects an electronic system to a remote server for real-time meteorological data analysis, allowing for electrical isolation of the system before a voltage surge occurs, using a control circuit to assess danger levels and initiate disconnection when thresholds are exceeded, thereby preventing damage from adverse weather events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If passive components like varistors or circuit breakers are integrated in the electrical installation, then the installation is protected against voltage surges, but these components deteriorate over time and can only absorb a limited amount of energy
Solution Approach 1:
The system performs preliminary action by monitoring meteorological data and disconnecting the electrical installation from the network before a voltage surge occurs. The control circuit receives meteorological data indicating an approaching storm, assigns a danger level, and commands disconnection of the electronic system before lightning strikes, thereby protecting components without requiring them to withstand surge energy.
2Reliability
If monitoring means wait for electromagnetic activity to exceed a warning level before disconnecting the installation, then the device can respond to thunderstorms, but there is a non-negligible risk that lightning damages the installation before disconnection
Solution Approach 1:
The control circuit performs preliminary action by analyzing meteorological data that indicates an approaching storm before electromagnetic activity from lightning occurs. The system assigns a danger level based on predicted meteorological conditions and commands disconnection in advance, eliminating the time delay between detection and protection activation.
Solution Approach 2:
The system replaces the electromagnetic field-based detection method with a meteorological data-based prediction system. Instead of monitoring electromagnetic waves from lightning, the control circuit receives and analyzes meteorological data indicating storm approach, enabling earlier detection and response before electromagnetic activity occurs.
3Reliability
If the electronic system is disconnected from the network before a voltage surge occurs, then damage is prevented, but the system requires real-time meteorological data collection and analysis infrastructure
Solution Approach 1:
The control circuit acts as an intermediary between the electronic system and the network. It receives meteorological data, analyzes it to assign danger levels, and commands the opening of electrical contacts to disconnect the system. This intermediary structure centralizes the protection logic and simplifies the overall system architecture.

AI summary
A method for protecting an electronic system against a voltage surge, which electronic system is connected to a telecommunication network and includes a control integrated circuit, the method including successively connecting the electronic system to a remote server containing meteorological data; recovering meteorological data originating from the remote server; analyzing by the control circuit the recovered meteorological data to assign thereto a danger level of the current or imminent meteorological event; and, when the assigned danger level exceeds a main warning threshold: sending by the control circuit a warning signal to a display terminal connected to the electronic system; displaying a first warning message on the display terminal from information contained in the warning signal, the first warning message warning a user of the display terminal of a risk of voltage surge due to the current or imminent meteorological event; and electrical isolating a port of the electronic system.
