Abstract
Technologies for detecting cyber-attacks against electrical distribution devices include a controller. The controller includes circuitry to determine a first measured value of a first operational parameter of a transformer based upon one or more signals received from one or more sensors of the transformer. The circuitry is also to determine a second measured value of a second operational parameter of the transformer based upon one or more signals received from the one or more sensors of the transformer, calculate a first expected value of the first operational parameter based on the second measured value of the second operational parameter and a model of the transformer that relates the first and second operational parameters, compare the first measured value of the first operational parameter to the first expected value of the first operational parameter, and identify when a difference between the first measured value and the first expected value exceeds a first threshold.
