Koorosh Moghadam

A senior power systems electrical engineer licensed in Ontario, working across power generation, transmission, and distribution for nuclear, heavy industrial, and utility-interface projects.

The work sits where the consequences of an error are expensive or worse: fault duties on equipment that has to interrupt them, relay settings that decide whether a fault clears selectively or takes the plant with it, ground grids that determine what happens to a person standing near a fence during a fault. These are questions with defensible answers, and finding them is the job.

The practice spans short-circuit and load-flow analysis, protection and coordination studies, arc-flash assessment, station and plant grounding, and medium-voltage cable systems — from the study that establishes the numbers through to the drawings that put them on site.

KM Engineering

KM Engineering is the practice behind this site: power systems studies and design, delivered as documents that survive review — a calculation someone else can follow, a stated source for every value, and an explicit note of where a method stops being valid.

These notes

The posts are working notes: problems that needed looking up twice, and answers that turned out to be less obvious than they first appeared. Corrections are welcome, and more useful than agreement — every post carries a comment box for exactly that purpose.

The tools

The calculators show their working, name the source of every value, and stop when a case falls outside what they cover rather than quietly interpolating. They are free and run entirely in the browser.
