Outstanding

Thanks

Hi, could you please tell me why is the voltage divider with the capacitor (R3, R4 and C1) connected to the common pin of the transformer and R2? I guess R3 and R4 are there to get (rise) the middle point of the waveform. But what is the purpose of the capacitor? Thank you for sharing.

[@thebrightlight9472]

All these components are combined to make a complete circuit in order to measure the AC Voltage. The resistors are used to divide the voltage and capacitors are used to store the charge.

Thank You

very informative video bro, I am working on 3phase DOL auto starter, whenever there will be voltage in 3phase pump should start, any idea where i get such project

[@thebrightlight9472]

You can make your project while keep in mind this video. In this just add pump to it. Because it already sensing the voltage.

@@thebrightlight9472 But, we dont have neutral connection, i mean only 3 phases, so i have to chech voltage between phases A,B,C then between A-B, A-C,B-C

[@thebrightlight9472]

Got it. You will need Delta connection then.

@@thebrightlight9472 ok, let me check that, if you know anything, any link please do share

[@thebrightlight9472]

I don't have it now. But if found, will share with you. Thanks

[@halimmudia5451]

Thanks brother

[@thebrightlight9472]

You Welcome brother.

[@AbdiasIr-h5z]

Can you send me your code, please?
