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.

Electrical installations where use of TN-C-S system is prohibited
A real danger can arise when the non-current-carrying metalwork of an installation is connected to the system’s neutral, as is the case with a TN-C-S-fed system. The ground system is effectively in parallel with the neutral and can thus share… Read more

Balancing of single-phase loads to achieve energy efficiency
All single-phase loads, especially those with non-linear characteristics, in an electrical installation with a three-phase supply should be evenly and reasonably distributed among the phases. Such provisions are required to be demonstrated in the design for all three-phase 4-wire circuits… Read more

Seven Methods To Avoid Insulator Flashovers
Contamination caused insulator flashovers produce frequent outages in severely contaminated areas. Lines closer to the ocean are in more danger of becoming contaminated. Several countermeasures have been proposed to improve insulator performance. The most frequently used methods are: Increasing leakage… Read more
