Dear Sir
I have designed the circuits for 50 HZ ,440 AC voltage i.e three phase . I have done only connecting two phase only like RYB:- RB , BY and RY so I have connected X rated capacitaor 470K/250 volts is series connected with each phase to 5408 diode bridge rectifier circuits to run 0.2 mili amps rely ON like this i am using 3 relays like RB , BY and RY . its working fine but whenever power is failure after the power is come it will damage the circuits . please help me
