An electronic circuit breaker provides waveform data wirelessly and alters a breaker code wirelessly. The breaker comprises a transceiver to wirelessly transmit information including waveform data, a microcontroller including a processor and a memory and computer-readable firmware code stored in the memory which, when executed by the processor, causes the microcontroller to: monitor in real-time breaker functional parameters to determine parametric modifications, wirelessly transmit the information that was saved previously in the electronic circuit breaker about the one or more breaker functional parameters to a remote device with a graphical user interface, alter a breaker algorithm after analyzing load data of problematic electrical loads in a mobile application (APP) of the remote device to treat the problematic electrical loads as normal and safe and test the computer-readable firmware code with a problematic electrical load to make sure the electronic circuit breaker doesn't still trip on the problematic electrical load.

The present disclosure provides systems and methods for generating a system-wide event report for electrical power delivery systems. A monitoring device within the power system may generate a key message upon the occurrence of a predetermined condition. A master IED within the power system may generate and/or transmit a system-wide key message to a plurality of monitoring IEDs within the power system. Digital process bus data, continuously recorded by a plurality of monitoring IEDs within the power system, may be saved locally by each monitoring IED within the power system and retrieved by a master IED within the power system. Alternatively, digital process bus data may be transmitted to a master IED and saved locally. A software and/or hardware module may be used to merge the local reports into a system-wide event report.
