It is understood that many new technologies have been applied in this power supply work. The power supply team uses robots for 24-hour duty in monitoring at the venue switch station. Infrared monitoring systems are used for monitoring electrical connections in areas where it is inconvenient for personnel patrols to perform. A ground nail anti-external damage system is used for external power cables to provide early warnings of external damage. For high-altitude electrical equipment such as venue lighting that is difficult to inspect on the ground, drones are used for close inspection to ensure the sound operation of equipment. Additionally, staff members use handheld partial discharge detectors, infrared thermometers and other non-contact detection methods to conduct real-time checks on various electrical equipment.
