Sensor Development

Sensor Development Efforts

Equipment sensor technologies inspect and assess the health of transmission line and substation equipment. These systems collect equipment health data, analyze the collected data, and display the information in meaningful ways. In addition to the development of individual sensors, EPRI is conducting research in:

  • Applications for sensor information
  • Data collection and communication
  • Power harvesting
  • Security
  • Algorithms
  • Data visualization methods

The goal of these efforts is to:

  • Ensure the safety of personnel
  • Increase the reliability of the electric system
  • Improve the efficiency of workforce deployments
  • Allow for condition-based maintenance

Transmission Line Sensors

Conductor/Connector Sensor

Efforts are currently focused on steel lattice and steel pole structures. The system is comprised of sensors that acquire diagnostic data from components of interest, communications hubs that collect the sensor data and relay it to a central repository, power systems for the sensors and hubs, algorithms to interpret the data, and visualization technologies to present information to users.

Additional information is available in the Transmission Line R&D Roadmap

Underground Transmission Sensors

Research and development related to underground transmission sensors is focused on identifying possible improvements to and automation of condition assessments of the cable systems. Areas of focus include:

  • Improvements to existing sensors
  • Development of more efficient power sources
  • Development of enhanced data collection systems
  • Improved integration with utility operation systems

Substation Sensors

Conductor/Connector Sensor

Efforts are focused on developing sensor technologies to acquire diagnostic data, improving power harvesting methods for those sensors, and enabling wireless communication of the collected data.
