  • Patent number: 11411389
    Abstract: Systems, methods, and computer-readable media are disclosed for identifying a fault using systems and methods for a controlled dynamic MHO characteristic. Particularly, the systems and methods described herein may automatically control the dynamic expansion of the MHO characteristic based on the estimation of uncontrolled dynamic MHO expansion estimation and maximum allowable expansion set by a user. This may provide flexibility in that, the MHO can be allowed to expand to a maximum level, when the estimated MHO expansion value is below the user defined maximum allowable expansion level, but also provides a controlled dynamic MHO when the estimated values are above the maximum allowable level.
