1. A hydraulic fracturing system for fracturing a subterranean formation comprising:

  • an electric motor;

    a pump coupled to the motor, and that has a discharge in fluid communication with a wellbore that intersects the formation, so that when the motor is activated and drives the pump, pressurized fluid from the pump pressurizes the wellbore to fracture the formation;

    a variable frequency drive in communication with the electric motor, and that controls the speed of the motor, and performs electric motor diagnostics to prevent damage to the electric motor;

    a source of electricity that is disposed a long distance from the electric motortransmission lines that connect the source of electricity to the electric motor and that span the long distance between the source of electricity and the electric motor; and

    a switch gear between the transmission line and the source of electricity, and another switch gear between the transmission line and the electric motor.
