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.

Practical lesson in grounding and bonding of Gas-Insulated Switchgear (GIS)
With the exception of SF6-to-air bushings terminals, all active portions of gas-insulated switchgear (GIS) are contained within grounded enclosures, which means that they are not susceptible to inadvertent contact. This makes gas-insulated switchgear intrinsically safe. In addition, numerous grounding procedures… Read more
