With the rapid development of modern power electronics technology, inverter systems play an increasingly important role in various power applications. The reliability of inverter systems directly affects the stable operation of the entire power system. However, in long-term operation, bus short-circuit faults often become a significant factor affecting the reliability of inverter systems [1]. Therefore, researching effective bus short-circuit fault detection and repair technology holds important theoretical significance and practical application value.
In recent years, with the large-scale application of renewable energy, the demand for inverter systems has increased significantly, especially in the fields of photovoltaic and wind power generation. According to data from the International Energy Agency (IEA), the installed capacity of global photovoltaic and wind power generation has grown at an annual rate of over 20% in the past decade. This growth poses higher demands on the reliability of inverter systems. Bus short-circuit faults not only lead to reduced system efficiency but can also trigger severe safety incidents [2].

2. Causes and Impacts of Bus Short-Circuit Faults
2.1. Causes of Bus Short-Circuit Faults
Bus short-circuit faults are typically caused by various factors, primarily including external factors such as lightning strikes and natural intrusions, which may cause physical damage and electrical interference [3]; Internal factors such as material aging and loose connections, where material deterioration and mechanical connection instability over time can increase the risk of short-circuits; and design and installation issues, where improper design or nonstandard installation may lead to system failures during operation. Furthermore, environmental conditions such as temperature and humidity changes may exacerbate these problems, further increasing the probability of bus short-circuits [4]. Understanding these causes is crucial for formulating effective prevention and repair strategies, which helps improve the reliability of inverter systems and the overall stability of power systems. Bus short-circuit faults are typically caused by various factors, mainly including:
2.1.1. External Factors
Natural events such as lightning strikes, tree falls, and animal intrusions can cause mechanical damage or insulation failure of the bus. According to a study by the National Electrical Safety Code (NEC), about 20% of short-circuit faults are caused by external factors. Lightning strikes may cause transient overvoltage, thus damaging the bus insulation layer. Tree falls and animal intrusions can directly cause physical damage [5].
2.1.2. Internal Factors
Including issues such as bus material aging, loose connections, and insulation layer damage, which may gradually manifest over time. Studies have shown that material aging is one of the main internal factors leading to bus short-circuits, especially in equipment operating in high-temperature and high-humidity environments. Material aging not only reduces mechanical strength but may also lead to a decline in insulation performance.
2.1.3. Design and Installation Issues
Initial design flaws or errors during installation may sow the seeds for short-circuit faults. For example, unreasonable electrical load distribution and improper grounding design may increase the risk of short circuits [6]. According to statistics from a power equipment manufacturer, about 15% of short-circuit faults are related to design and installation issues. Negligence during the design phase may lead to unbalanced loads in the power system during operation, thereby exacerbating the stress on the bus.
2.2. Impacts of Bus Short-Circuit Faults
The impacts of bus short-circuit faults on inverter systems and their connected power networks are mainly reflected in the following aspects.
2.2.1. Equipment Damage
Short-circuit faults may cause severe damage to inverters and related equipment, and even trigger a larger-scale power system collapse. Fault currents can far exceed the equipment’s tolerance, causing catastrophic outcomes such as component burnout or explosions. According to reports from power equipment manufacturers, short-circuit faults are one of the main causes of equipment damage, accounting for more than 35% of all equipment failures [7]. Such damage not only increases the cost of equipment repair and replacement but may also result in long-term system downtime, affecting the overall reliability of power supply.
2.2.2. Power Supply Interruption
Short-circuits can lead to unstable or interrupted power supply, severely affecting users’ normal electricity needs. According to a survey by an international power grid company, short-circuit faults are one of the main causes of power interruptions, accounting for more than 30% of total interruption events. Power interruptions not only inconvenience residents’ daily lives but may also severely impact industrial production, resulting in production line shutdowns, product losses, and damage to corporate reputation [8]. Long-term power supply interruptions may also affect the operation of critical infrastructure, such as hospitals, financial systems, and transportation networks.
2.2.3. Economic Losses
The costs of equipment repair or replacement, as well as the economic losses caused by power outages, can be enormous. According to data from the United States Department of Energy, power outages cause annual losses of up to 150 billion USD to the U.S. economy. These losses not only include direct costs of equipment repairs and replacements but also indirect losses due to production delays, contract breaches, data loss, and customer attrition resulting from power outages [9]. Additionally, frequent power outages may lead enterprises to increase investments to improve the reliability of power infrastructure, further increasing operational costs.
