Abstract
An electronic protection system is implemented in an electrical panel that distributes electricity to branch circuits at a site. The electronic protection system includes a current sensor, an actuator and a processor. The current sensor senses a current flow through a branch circuit. The actuator is used to de-energize the branch circuit. The processor controls the actuator based on the current flow sensed by the current sensor, according to a trip-time curve implemented by the processor. The trip-time curve specifies a maximum duration of current flow for different amounts of current flow.

An electronic protection system implemented in an electrical panel for a site, wherein the electrical panel distributes electricity from a source to branch circuits at the site, the electronic protection system comprising:
- a current sensor configured to sense a current flow through a branch circuit;
- an actuator configured to de-energize the branch circuit;
- and
- a processor that controls the actuator based on the current flow sensed by the current sensor and according to a trip-time curve implemented by the processor, wherein the trip-time curve specifies a maximum duration of current flow through the branch circuit for different amounts of current flow through the branch circuit;
- wherein the current sensor, actuator and processor are all implemented in the electrical panel.
An electronic protection system implemented in an electrical panel that distributes electricity to branch circuits at a site, the electronic protection system comprising:
- multiple current sensors configured to sense current flow through different branch circuits;
- multiple actuators configured to de-energize the branch circuits;
- and
- a processor that controls the actuators based on the current flows sensed by the current sensors according to trip-time curves implemented by the processor, wherein at least two of the branch circuits are controlled by different trip-time curves, and each trip-time curve specifies a maximum duration of current flow for different amounts of current flow.
