Title: Autonomously powered inductively coupled time domain reflectometer sensor device

Abstract

Devices, systems and methods for use of an autonomously powered inductive time domain reflectometer sensor device are provided. A sensor device for a power line can include a first induction coil and a second induction coil coupled to the power line and a control device. The first induction coil can be configured to inject a first signal on a power line by inducing a first current on the power line. The second induction coil can be configured to inject a second signal on the power line by inducing a second current on the power line. The control device can be configured to control the second induction coil to inject the second signal to cancel a portion of the first signal. As a result of the second signal cancelling a portion of the first signal, the first signal can be configured to propagate in a single direction on the power line.
