The EPRI Overhead Conductor Monitor is a robust, low-cost device designed to measure and report various parameters related to overhead conductors. It addresses issues such as aeolian vibration, conductor galloping, blowout, and ratings. The monitor uses a range of sensors and integrated algorithms to calculate conductor motion and rating metrics, providing near real-time data to utility stakeholders via a web portal.

The device operates by measuring conductor temperature with a patented thermocouple design, current flow through magnetic field coupling, and conductor motion using a 3D accelerometer and gyroscope. These monitors capture data in six axes, which is then processed by integrated algorithms to calculate metrics like displacement and dominant frequencies. The data is wirelessly transmitted to a base station and then to a central server, where it can be accessed and analysed.
