1. A system for making real-time predictions about an arc flash event on an electrical system, comprising:

  • a data acquisition component communicatively connected to a sensor configured to acquire real-time data output from the electrical system;

    an analytics server communicatively connected to the data acquisition component, comprising,a virtual system modeling engine configured to generate predicted data output for the electrical system utilizing a virtual system model of the electrical system,an analytics engine configured to monitor the real-time data output and the predicted data output of the electrical system, the analytics engine further configured to initiate a calibration and synchronization operation to update the virtual system model when a difference between the real-time data output and the predicted data output exceeds a threshold,a decision engine configured to compare the real-time data output against the predicted data output to filter out and interpret indicia of electrical system health and performance; and

    an arc flash simulation engine configured to utilize the virtual system model to forecast an aspect of the arc flash event; and

    a client terminal communicatively connected to the analytics server and configured to communicate the forecasted aspect.
