A system and method for nuisance-trip decision management in an electric power system using data analytics comprising, a protection system, PS, and at least one electrical protection circuit, EPC. The PS comprising, a plurality of sensors configured to measure data; a memory configured to store an updated data of nuisance-trip events and a plurality of nuisance-trip parameters detected or generated on the electric power system over a period; a processor configured to perform hybrid machine learning (HML) based on the measured data from the plurality of sensors for a nuisance-trip condition and communicate with a neighboring PS; a protection microcontroller configured to allow or avoid tripping at least one electronic tripping circuit provided in the at least one EPC by communicating with the processor and the neighboring PS.

Nuisance trip decision management using data analytics in electrical protection system

A circuit breaker is described herein. In one aspect, the circuit breaker includes a communication module, a non-transitory memory device, and a memory controller. The communication module is configured to receive protection settings and breaker information from a trip unit coupled to the communication module. The protection settings and the breaker information are received upon powering-on the trip unit. The non-transitory memory device is configured to store the protection settings and the breaker information associated with the circuit breaker. The memory controller is configured to cause the protection settings and the breaker information received to be written to the non-transitory memory device.

Circuit breaker having breaker information module and method of use

An electronic trip device is described that includes a test current generator and a leakage current detection circuit. The test current generator is coupled to a conductor and configured to provide a test current having a magnitude to the conductor in response to a selection to test the electronic trip device. The conductor is a line conductor or a neutral conductor. The leakage current detection circuit is configured to detect a current difference between the neutral conductor and the line conductor. The leakage current detection circuit is configured to provide, in response to the selection to test the electronic trip device, a tripless error indication if the detected current difference is less than a first threshold value.
