Abstract
An integrated fracturing system includes a fracturing pump, an electric motor positioned to drive the fracturing pump, a variable frequency drive positioned to provide variable frequency power to the electric motor, a master controller, and a diagnostic sensor. The master controller is positioned to provide energize and speed commands to the VFD. The diagnostic sensor is coupled to the electric motor positioned to measure diagnostic data. The diagnostic sensor is in communication with the master controller.
