Electric Power Monitoring System (EPMS) efficiently acquires and securely transmits a plethora of electrical data and statuses within the power supply and distribution systems of data centers. It processes vast amounts of data and presents it through a more user-friendly graphical interface. Consequently, operations and maintenance personnel are enabled to effortlessly monitor circuit and equipment statuses, as well as access fault diagnosis and analytical results; Utilizing the EPMS master station platform, operations and maintenance staff can execute and manage daily tasks remotely and in a unified manner, thereby maximizing rapid response capabilities and operational safety. This, in turn, substantially elevates work efficiency.
