I am working with one of my friend's project. Who requested me to find out the appropriat circuit diagram for this.
The goal of this project is satisfying the following tasks:
1. Connect the loads to the PDB supply when supply is available on PDB.
2. When supply failure occur on PDB line, start up the standby 3 phase alternator automatically and switch the loads to the alternator.
I have given here the developed ladder diagram designed by me. I am using relay, magnetic contactor and timer for this propose. But one problem is that I noticed here, when power failure will occur, the timer will be no longer getting the supply. I am looking for any kind of help, recomandation, or even better practical circuit diagram for this project. I will be thankful if anyone can help me.
