Forest Fire Risk Mitigation Strategies

Communication schemes are not required to implement FLISR, but they enhance automation capabilities by providing real-time visibility for faster and more sophisticated responses, especially with larger numbers of devices. Alternatively, noncommunicating loop schemes can be implemented in such a way that reconfiguration decisions are made based on voltages, currents, and operations in the circuit (usually limited to 15 devices). Some automation platforms can support both types of schemes.

Vendors can provide scripted or model-based automation options in single switches and multi-loop configurations. While scripted solutions rely on pre-programmed logic, model-based solutions leverage real-time data and system modeling to dynamically adapt. The choice between the two depends on the scale of the existing utility system, the need for future scalability, and the complexity of user-defined contingencies.

Working together

G&W Electric offers the CLiP current limiter, which works by detecting and reducing the voltage and current of downed power lines to prevent arcing. It then signals the upstream G&W Electric Viper-ST circuit breaker to open and clear all three phases. At the same time, the current limiters can signal its LaZer automation platform to compensate for downed lines, reducing the risk of power outages for customers. All of these functions are supported by a sensor-based, real-time monitoring system.

In addition to infrastructure modernization

Utilities operating in regions with a high risk of wildfires should consider taking additional actions to reduce their risk:

• Vegetation management – ​​Regular vegetation management around power lines can play a key role in preventing wildfires.
• Community Collaboration – Utilities can work with fire departments, local governments and surrounding communities to develop comprehensive wildfire mitigation plans and communications strategies.
• Public awareness – Educating the public about wildfire risks and safe practices can help prevent accidental ignitions.

Community Protection

By combining advanced equipment and technology, a modern DA system, and comprehensive knowledge of wildfire risk, utilities can enhance the safety, reliability, sustainability, and resilience of their energy grids and protect the communities they serve from wildfires and many other threats.
