New type of fault device for electric competition source code

This project uses the 430 series MSP430F5310 microcontroller as the central processing unit to develop a new type of fault indicator to indicate phase-to-phase short circuit faults and single-phase ground faults that occur on transmission and distribution lines of 10KV and below. Its main working process is: sensing real-time voltage and current values ​​from the high-voltage line, and sending them to the microcontroller for analysis and calculation after hardware processing. If the fault conditions are met, a flop signal is sent to cause the indicator to flop, and the action information is transmitted wirelessly. The communication module transmits the information to nearby communication substations.

atmega8-328 prototype board: good voltage filtering function

This board was created for the mcudude library and has good voltage filtering, reducing reset time via a c10 capacitor (10nF!!) on the dtr line of a ch340 system. It would be nice to solder a precision socket under the x1 oscillator, it gives you the opportunity to try different frequencies (useful for rs232 communication for example)​
