Abstract:
Auto Restart Circuit solved the sudden start of the motor which cause the
breakage of the shaft which connect the motor to the pump due the reversal
rotation of the shaft, and will also solve the time loss caused by the operator (if
we consider that there was an operator who operate and perform the restart of
the pump) because the wellhead is far away from central process facility.
Here comes the smart relay part to solve the above problems we need to set the
smart relay to start the pump after specific time ( when reverse rotation stop ) ,
so by connecting smart relay with the Variable Speed Drive (VSD) to perform
the auto restart operation we will cause a reduction in the errors
