I have 30 years of experience, and specialize in the field of electrical power systems with specific knowledge in the areas of cables, transformers and other electrical machines. I have published on such topics as transformer modeling for electromagnetic transients, cable and transformer thermal rating and power system studies including smart grid. I have made contributions to the solution of the problem of power definitions in non-linear circuits. I have obtained a solution to the theoretical problem with the definitions of power in nonlinear circuits. When this theory becomes fully developed it has the potential to change the way electricity is measured and billed.
