Zusammenfassung:	The present disclosure pertains to a line-powered current measurement system to mount to an electrical conductor and related methods. In one embodiment, a system may comprise a current transformer to electrically couple to an electrical conductor and to generate a secondary current proportional to a primary current in the conductor. A power harvesting subsystem may harvest power from the secondary current in a first configuration. A switching subsystem may transition the line-powered current measurement device between the first configuration and a second configuration, in which a current measurement subsystem generates a measurement of the secondary current. The switching subsystem may provide the secondary current to the power harvesting subsystem in the first configuration and may bypasses the power harvesting subsystem in the second configuration. A communication subsystem may transmit the measurement of the secondary current to a receiver device.
