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.

Geothermal Energy
How a Geothermal Plant Works?
Understanding geothermal energy begins with an understanding of the source of this energy – the earth’s internal heat. The Earth’s temperature increases with depth, with the temperature at the center reaching more than 4200 °C (7600 °F). A portion of… Read more

Power Substation
Why and how much for fire protection of power plant?
Fire protection measures can be subdivided into life-safety and investment categories. Life-safety measures are considered to be mandatory by fire codes, building codes, or safety codes. As such, the codes mandate specific types of substation fire protection, with very little… Read more

Electric Motor
5 steps to choose the best motor for your application
For line-operated motors, loads fall into three general categories: constant torque, torque that changes abruptly, and torque that change gradually over time. Bulk material conveyors, extruders, positive displacement pumps, and compressors without air unloaders run at relatively steady levels of… Read more
