Auto Phase Selector Using Arduino With Voltage Sensing

Our project is auto phase selector. If we have 3 phase & we are using appliances load on phase-1. As phase-1 missed , our appliances load automatically shifted to phase-2.

If phase-2 missed,our appliances load automatically shifted to phase-3. If phase-1 goes normal, then our appliances load automatically shifted to phas1-1.

In this project you have one threshold level voltage, for example if you have select it to 220V. If phase-1 voltage is below then threshold level – 5 volt, then our load automatically shifted to phase-2 . Same working as phase-2 to phase-3. If phase-1 voltage goes normal then our load automatically shifted to phas-1.

Project customization is also available.
