The Raspberry Pi uses algorithms to process the data and then sends the results to a cloud platform like Firebase, which is connected with a cross-platform application. Using an esp8266-based microcontroller, the sensors read data and transfer it to a Raspberry Pi-based server. The distribution board will be connected to several sensors such as a current sensor, voltage sensor, and power sensor. In an electrical system, proper power factor reduces the load on the electrical distribution system, promotes energy efficiency, lowers electricity costs, and reduces the likelihood of equipment instability and failure. The system also delivers information about the real time power factor, energy consumption, etc. As a result, we propose a system that will identify or detect any electrical system defects and warn the user in real time. A quick response time will help to limit the number of fatalities and financial damages associated with these events.

This suggests a highly skewed distribution along with a wide variation in peak latencies The whiskers represent 1.5 times the inter-quartile range. The line represents the median value, with the box representing interquartile range. Boxplots of the latencies for the individual peaks (shown as black dots) plotted for each ERP component (MMN on the left side of each figure P3a on the right side of each figure) by centrality (Central on the left figure frontal on the right figure) by laterality (Left, Center and Right).

We compared ERPs elicited by infrequent randomly occurring omissions (unexpected silences) in tone sequences presented at two tones per second to ERPs elicited by frequent, regularly occurring omissions (expected silences) within a sequence of tones presented at one tone per second. If these components reflect prediction error, they should also be elicited by omitting an expected sound, but few studies have examined this. Predictive coding can be indexed in electroencephalography (EEG) with the mismatch negativity (MMN) and P3a, two components of event-related potentials (ERP) that are elicited by infrequent deviant sounds (e.g., differing in pitch, duration and loudness) in a stream of frequent sounds. According to predictive coding, the brain predicts incoming sounds, compares predictions to sensory input and generates a prediction error whenever a mismatch between the prediction and sensory input occurs. The human auditory system excels at detecting patterns needed for processing speech and music.
