Electrical Faults Detection System Using Arduino.

Arc faults detection system a system which will automatically detect arc faults, cuts power occurred at electrical circuit system in house and reports the situation to the appropriate personnel. In an electric power system, a fault is detected by any abnormal electric current follow. There are two types of arc fault, series and parallel arc fault.

System Requirement Analysis

Functional requirements 

1. The system shall be able to detect occurrence of arc fault

2. The system shall be able to provide mechanism for electrical disconnection to isolate the entire system on the occurrence of fault

3. The system shall be able to send SMS to consumer’s mobile phone reporting the occurrence of fault

4. The system should be able to respond on consumer’s commands whenever is necessary

 Non-functional requirements

  1. Performance: The system will operate in real-time environment i.e. the decision will be taken as quickly as possible.
  2. Reliability: The system will operate around 24 hours automatically

Hardware Requirement

  1. Arduino Un

It will be programmed to be able control the Ethernet shield to send report to the user through the internet.

  1. Arduino Ethernet shield

With the presence of this shield the Arduino data can be accessed anywhere in the world since the module can be programmed to have IP, MAC address, subnet mask and default gateway hence even telnet functionality is possible because of the module.

  1. Current sensor

Purpose of change those ac currents from ac to DC with same values it’s to enable us to control those accrued behavior of passing currents to determine presence of arc fault.

  1. Power supply design

Hardware requirement for power supply design: Transformer, Rectifier (bridge rectifier), Capacitor, Voltage regulator, Circuit board, Wires.

Software Requirement

  1. Arduino software

The software like Platform IDE used for writing and running (executes) codes during programming of Arduino microcontroller

  1. Proteus

This is used to simulate the circuit so that with the Arduino library in it could give the desired output.
