PM165 station-controlled intelligent power distribution diagnosis device.
This device is highly integrated with powerful functions despite its small size. The PM165, a station-controlled intelligent power distribution diagnosis device, is developed based on high-frequency sampling of electrical quantities and time sequence feature identification technology in the field of power distribution and consumption. It can be widely applied in 0.4/0.69kV low-voltage power consumption systems and medium and high voltage power transformation and distribution systems of 6kV and above.
The PM165 achieves highly integrated functions. In addition to the functions possessed by conventional multifunctional power meters, it can also realize voltage sag/swell monitoring, power outage fault cause discrimination (short circuit/overcurrent/overstepping/power outage/overtemperature/leakage current/arc), three-phase fault arc detection, residual current detection, temperature warning for 12 switch contacts, and fault recording.
The PM165 supports RS485 wired communication interface and can be easily connected to the expertpower cloud platform, third-party cloud platforms, and local monitoring systems. Thus, it can realize short circuit fault identification, power outage cause diagnosis, voltage sag/swell identification and disturbance direction judgment, and three-phase fault arc detection.
The PM165 has excellent product characteristics and a graphical display and control interface. Its powerful sensing and information output capabilities contribute to building an energy Internet of Things and realizing high-dimensional applications of energy digitization.
