Siemen’s new solution for monitoring high-voltage lines

Siemens Smart Infrastructure recently launched its new PowerLink CM, a condition monitoring solution for high-voltage AC and DC transmission lines. To ensure reliable power supply, optimize grid utilization and prevent blackouts the device is designed to precisely locate faults in the transmission grid and continuously track line conditions. One single PowerLink CM device is sufficient to monitor line lengths of up to 500 km. Faults as well as line condition can be detected in powered, unpowered or grounded lines. Fault reports are received by the affected substation and are forwarded from there to the control room. For continuous line monitoring, the device can be connected to MindSphere, the open cloud-based Internet of Things (IoT) platform from Siemens, which facilitates transparent processing of all line data in the cloud.


This allows grid operators to analyze status reports and optimize maintenance activities.


  • One single device for lines of up to 500 km
  • Monitoring for powered, unpowered or grounded lines
  • Highly precise localization of line faults
  • Simplifies maintenance and increases network reliability

“With the new PowerLink CM solution, transmission grid operators can detect and locate possible line problems before causing major transmission network issues,” said Robert Klaffus, CEO Digital Grid at Siemens Smart Infrastructure. “PowerLink CM supports predictive operations management. Transmission grid operators can better manage their assets, avoid blackouts, and guarantee a reliable supply of electricity.”
