Title: Breaker Racker (Eaton)
Date: 2018(Fall)-2019(Spring)
College: UNCA/NCSU
Status of Completion: In Progress
Brief: This project is meant to upgrade a device named MRR1000(description below) to be wireless, automate position changes, implement feedback on the remote controller, automate clitch slip detection, and eliminate manual operation and indicators as much as possible.
What I'm doing to upgrade this device is incorporating two microcontrollers (ESP32 Devkit4 for Racker and ESP32 Wrover kit3 for remote and LCD) to replace all existing analog device with digital logic. The ESP32's are Bluetooth enabled with many General Purpose Input/Output (GPIO) to help complete this upgrade. I have established Bluetooth connection along with LCD programming and all logic required. I have also designed the circuit boards for this project to be implemented for final production.
Device Description: The MRR1000 is a device designed and developed by Eaton Corp. that allows operators to close, open, and remove breakers without the need to be within in the arc flash zone(injury/death zone).
