Electrical failures caused by electrical joints, cable joints, moisture, overload, short circuit, excessive contact resistance of battery joints, water immersion, small animals, etc. inside high and low voltage distribution cabinets lead to power outages, seriously affecting power safety and production, and causing immeasurable economic losses. Several reasons, such as overload of electrical components or cables and excessive contact resistance, are all caused by the heating of conductors, which causes a large number of electric particles in electrical or cable materials. Since there are relatively many components and joints inside high and low voltage distribution cabinets, traditional manual inspection methods cannot timely issue problems, and failures caused by temperature rise or moisture are very hidden. High-tech acquisition technology with high accuracy and fast response time must be adopted. Online services can meet the precise monitoring of various electrical distribution systems. It has high accuracy, fast response, and multi-functional monitoring such as monitoring, early warning, analysis and judgment, display, and linkage in the early internal air of the distribution system, which will completely solve the problem of eliminating electrical safety hazards.

The main heating elements of electrical faults in high and low voltage distribution cabinets are the particles decomposed by the wires and protective electrical joints when heated, which can detect electrical faults in high and low voltage distribution cabinets at an extremely early stage.

When an electrical fault occurs, the material decomposes into particles and gases when heated. This is the smallest material component in which such particles can exist in a free state. Regardless of the cause of the electrical fault, the early stage is manifested as the heating of the object, the release of particles, gas, and the generation of odor. The main heating elements of electrical faults in high and low voltage distribution cabinets are cables, load switches and protectors. The particles decomposed by heating in the distribution cabinet are mainly smoke particles and gas molecules. Using laser particle sensors, measuring particles can monitor the concentration of particles and gases generated by overheating and decomposition of electrical equipment such as polyvinyl chloride insulated cables, lead-acid batteries, circuit breakers, and load switches, and implement alarms before visual smoke is generated to determine the heating of the insulator, so as to achieve extremely early monitoring of electrical faults and prevent them before they happen.
