1750 awesome technical articles
Hi, I'm an electrical engineer, programmer and founder of EEP - Electrical Engineering Portal. I worked twelve years at Schneider Electric in the position of technical support for low- and medium-voltage projects and the design of busbar trunking systems.
I'm highly specialized in the design of LV/MV switchgear and low-voltage, high-power busbar trunking (<6300A) in substations, commercial buildings and industry facilities. I'm also a professional in AutoCAD programming.

Measurement of residual currents on a distribution feeder
The measurement of the earth fault or residual currents on a distribution system feeder can be done by the so-called summation connection, where the three current transformers, one in every phase, are connected and the summated current is brought to… Read more

When You Ground Ungrounded System With Grounding Transformer
The common grounding assumes a wye-connected neutral to ground. As this is not always the case, and in some cases it is not a three-phase system that it is desired to be grounded. For situations of this kind a grounding… Read more

Underground substations – Out of sight, out of mind
Underground substations help to bring high voltage electricity directly into the city center. The stations are environmentally friendly, almost unnoticeable, and have none of the planning problems encountered by surface-built solutions. Building new transformer substations in inner-city zones or expanding… Read more
