1. An electric driven hydraulic fracking system to pump a fracking media into a well to execute a fracking operation to extract a fluid from the well, comprising:
a Variable Frequency Drive (VFD) is configured to drive an electric motor that is associated with the VFD to control the operation of the electric motor to drive a hydraulic pump associated with the VFD and the electric motor; and
a controller associated with the VFD is configured to:
monitor a plurality of temperature parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether at least one temperature parameter deviates beyond at least one corresponding temperature parameter threshold, wherein each of the temperature parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system, and
initiate at least one corrected action when each temperature parameter deviates beyond the at least one corresponding temperature parameter threshold, wherein initiating at least one corrected action when each temperature parameter deviates beyond the at least one corresponding temperature parameter threshold maintains the operation of the electric driven hydraulic fracking system.
