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.

When a 3-phase motor expirience phase failure, what a mess…
A phase failure is an interruption of a single conductor. The motor then continues running with two phases and can suffer damage. The cause is, for example, blown fuse. Small to medium sized motors are mostly stator critical – this… Read more

How electricians test continuity of protective conductors
For all protective conductors, including main and supplementary bonding conductors, electricians must perform continuity test using a low-reading ohmmeter. For main equipotential bonding, there is no single fixed value of resistance above which the conductor would be deemed unsuitable. Each… Read more

Where do electrical faults occur the most?
A fault is not a natural occurrence. It is an unplanned event which occurs unexpectedly. Electrical faults in an electrical installation or piece of equipment may be caused by: Negligence (that is, lack of proper care and attention), Misuse (that is,… Read more
