“…The following sections summarize previous research carried out to advance the prediction, detection and prevention of wildfires. A detailed explanation of condition assessment technologies for power distribution infrastructure to detect/predict potential power line faults is not presented here and it can be found in the previous works of the authors [23,26,55].…”

Wildfires are one of the most hazardous natural disasters in Australia in terms of fatalities, property damage and financial losses. Events of catastrophic wildfires are recorded across the world including in the United States and Canada. Failures along power distribution infrastructure and network faults have been identified as some of the causes for the initiation of wildfires. Thus, it is critical to better understand the mechanisms and the potential prevention strategies for wildfires caused by power distribution system faults. In this light, this paper presents how the power distribution network faults cause wildfires highlighting the main mechanisms. Further, this paper reviewed studies on recent advancements for the prediction, detection and prevention of wildfires. Condition assessment of power distribution infrastructure including poles, crossarms, overhead cables and other attachments are paramount to detect potential defects and to carry out timely replacements which can subsequently mitigate the possibility of wildfire initiation. Therefore, this paper summarized the studies on condition monitoring and surveillance techniques for power distribution infrastructure. Altogether, this paper aimed to enhance the awareness about the prevention strategies for wildfires caused by power distribution system faults.

“…The main components in power distribution networks are overhead conductors (cables), utility poles, crossarms, transformers and substations [23]. Timber is a widely used material for utility poles and crossarms, due to its relative advantages compared with other alternative materials such as steel, concrete and composites [24].…”

“…In dry, hot, humid and windy conditions, sparks generated from a power distribution fault can ignite the biomass, initiating a fire. It is vital to monitor the structural health of power distribution systems to avoid potential faults, and power distribution infrastructure reaching the end of service life needs to be replaced [54][55][56][57]. A detailed investigation into the causes of the Black Saturday bushfires in Australia revealed that a power line brought down by high winds generated sparks that initiated the fire in the Kilmore East region, where 121 people were killed and approximately 100,000 ha burned in less than 12 h [2].…”

“…Preventive measures to minimise the adverse effects of bushfires include relocating assets to fire-free or less exposed places, increasing the robustness of infrastructure to resist fires and managing flames responsibly. In addition, bushfires initiated due to the failure of the power distribution infrastructure can be minimised by employing accurate and reliable condition assessment techniques to detect their defects at an early stage [50,54,55,152]. Failure preventive maintenance should be carried out to have safe power distribution infrastructure.…”

Bushfires are classified as catastrophic disasters capable of inflicting significant destruction. The key detrimental consequences of bushfires include the loss of human lives, trauma within communities, economic losses and environmental damage. For example, the estimated economic loss from the September 2019 to March 2020 bushfires in New South Wales (Australia) was about AUD 110 billion, including more than 3000 burned houses. There has been a notable increase in both the frequency and intensity of bushfires, as clearly demonstrated by recent bushfire events. Bushfires are an intricate phenomenon that transpires across various spatial and temporal scales. Further, the changing circumstances of landscapes, vegetation patterns, weather conditions and ecosystems account for the complexity. Therefore, continual attention is essential for the development of bushfire management strategies. In this context, this paper undertakes a comprehensive literature review of bushfire management strategies, encompassing aspects such as bushfire prediction, detection, suppression and prevention. Based on the review, a bushfire management framework is proposed that can eliminate or successfully mitigate the consequences of bushfires. Further, the paper delves into the domains of fire weather conditions, the initiation of bushfires and the adverse consequences stemming from these fires. Both terrestrial and aerial remote sensing methods have proven to be effective in predicting and detecting bushfires. Nevertheless, a simple unique solution cannot be proposed for bushfire management. Changing weather conditions, topography and the geographic mix of asset types need to be considered when deciding on bushfire management strategies and their breadth and depth of application.
