    > Hello, 

         I want to design a circuit for protecting single phase motors against under voltage which is the big
    problem in my area, also to protect in case of over voltage which may be caused with anything like 
    lighetining, please I need your support as soon as you can and if possible a circuit diagram which I will 
    develop. Single phase supply in my area is 220v – 240v.

    To protect your single phase motor i give you a solution, you can find the AVS(Auto Votage Stabilizer)the could find any electrical shop in your area, but to protect the over voltage such as lightning you must consult with electrical company that supply Surge Arester, it is a similar kind of circuit breaker but different function. for circuit diagram will included with their product.

     

    Thanks

    You can use ordinary 3f under and over voltage relay on busbar, and use that voltage status for 1f aplication

    you should use undervolatge and overvoltage relays accordingly.
