In our land we are using 15HP submersible pump, we use capacitor for run the pump in 2Phase.

every time when power changeover from two Phase to three phase we need to add and remove the capacitors and start the pump.

so i want automatic changeover of 3Ph to 2Ph circuit, please help

Where do you have 2 phase available? o_O

Do you mean split single phase like is standard in the North American power systems?

Please make a few drawings
a:in star 3Ph
b:in star 2ph
c & d for Delta
This to allow us what you want.

I guess the OP's problem is that he has a 15 HP 3 Phase motor; and when 1 phase fails, to "generate" the missing phase by setup of capacitors.
He wants to automate the process.

As Picbuster said, let's have the schematic for the 2 phase and 3 phase operations.
