1. A method for analyzing effects of electrical perturbations on load(s) in an electrical system, comprising:
processing energy-related signals from at least one intelligent electronic device (IED) in the electrical system to identify an electrical perturbation in the electrical system, the electrical perturbation including at least one of a sag, a swell, a transient, an interruption, and a long-duration root-mean-square (rms) variation;
determining an end time of the electrical perturbation;
analyzing electrical measurement data from prior to, during and/or after the end time of the electrical perturbation to identify and quantify the effects of the electrical perturbation on load(s) in the electrical system, the effects of the electrical perturbation on the load(s) including load restarts due to the electrical perturbation; and
taking one or more actions to reduce the effects of the electrical perturbation on the load(s) and extend the life of the load(s), the actions including at least one of communicating the load restarts and controlling at least one component in the electrical system.
