  • Publication number: 20160359311
    Abstract: Method(s) for limiting current in an electrical circuit having transmission wires for power transmission include determining whether an unexpected operating condition exists along the transmission wires and limiting the current to prevent (damage caused by) the unexpected operating condition. The method may further include disabling the electrical circuit if the unexpected operating condition persists. Additionally, a system includes a power source, a solid state power controller (SSPC) configured to operate in a first conducting state and a second non-conducing state, and a controller.
