PM162 rail-mounted intelligent power distribution diagnosis device.
Highly integrated functions, small size but great wisdom.
■ The PM162 (rail-mounted intelligent power distribution diagnosis device) is developed based on the electrical quantity high-frequency sampling and time sequence feature identification technology in the field of power distribution and consumption. This product can be widely used in 0.4/0.69kV low-voltage power consumption systems and 6kV and above medium and high voltage power transformation and distribution systems.
■ The PM162 realizes highly integrated functions. In addition to the functions of a conventional multifunctional power meter, it can also realize functions such as voltage sag/swell monitoring, power outage fault cause discrimination (short circuit/overcurrent/overstepping/power outage/overtemperature/leakage current/arc), three-phase fault arc detection, leakage current and temperature monitoring and early warning, and fault recording.
■ The PM162 supports multiple communication interfaces such as wired and wireless. It can be easily connected to the expertpower cloud platform, third-party cloud platforms, and local monitoring systems, and can realize short circuit fault identification, power outage cause diagnosis, voltage sag/swell identification and disturbance direction judgment, three-phase fault arc detection, etc.
■ The PM162 has excellent product characteristics, is easy to deploy and convenient to use. Its powerful sensing and information output capabilities help build an energy Internet of Things and realize high-dimensional applications of energy digitization.
