In power plants, busbars connect numerous electrical devices, and an arc flash fault can lead to severe consequences. The VAMP40 module leverages its rapid arc flash detection and protection functions to monitor the busbar area in real time. When an arc flash fault occurs on the busbar, it acts promptly to cut off the faulty circuit, protecting the busbar and connected equipment, minimizing equipment damage and power outage scope, and ensuring the safe and stable operation of the power plant. For example, a large thermal power plant installed VAMP40 modules in its busbar protection system, successfully addressing multiple arc flash risks caused by insulation aging without leading to large-scale power outages.

The VAMP40 module is used for industrial motor protection, providing comprehensive protection for motors controlled by asynchronous circuit breakers. In a steel plant, for instance, its large motors may fail due to various reasons. The VAMP40 module real-time monitors parameters such as motor current and voltage, sending alarm signals or cutting off the power immediately in case of anomalies. Additionally, its arc flash protection function safeguards motor junction boxes and switchgear, ensuring the safety of motors and related equipment and reducing production interruptions caused by motor failures.

Marine platforms have harsh environments and extremely high reliability requirements for electrical equipment. The VAMP40 module's compact shape and wide power adaptability make it well-suited to the space constraints and complex power conditions of marine platforms. It protects cable feeders, motors, etc., on the platform by real-time monitoring line current, voltage, frequency, and other parameters, detecting and protecting against faults promptly. Its arc flash protection function also effectively addresses potential arc flash faults, ensuring the stable operation of the marine platform's power distribution system and providing reliable power support for production and daily activities on the platform.
