1758 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.

The art of arc-protection relaying in MV applications
Arc-flash detection relays are superior and provide much faster arc-flash detection times compared to the differential relays. With modern arc-flash detection technology, this detection time is of the order of ¼ cycles or even lower, based on 50/60 Hz. High-speed…...

The analysis of MV/LV incoming supply configurations for large industrial plants
The metal-processing industry is an excellent example where you can find specific large industrial plants. Why specific? Maybe because in such plants, there are only a few individual large loads that have to be connected directly to the MV system…....
