Patent ID: 10459025

Abstract:
The present disclosure pertains to systems and methods for reducing startup times of line-mounted fault detectors. A line-mounted fault detector may comprise a power harvesting subsystem and an energy storage subsystem configured to store electrical energy. A fast-start power coupling subsystem may receive power from the energy storage subsystem in a startup state and provide power to a subset of components. A DC-DC converter subsystem may start up after a voltage of the energy storage subsystem exceeds a threshold. A control subsystem may transition the line-mounted fault detector to an operating state once the DC-DC converter has started and may de-energize the fast-start power coupling subsystem. The control system may enable a flow of electrical energy from the DC-DC converter to the fast-start subsystem. A fault detection subsystem in electrical communication with the DC-DC converter subsystem may communicate an indication of a fault via an RF transmitter subsystem.
