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.

Tips for power factor correction and good protection of capacitors
Loads such as induction motors draw significant reactive power from the supply system, and a poor overall power factor may result. The flow of reactive power increases the voltage-drops through series reactances such as transformers and reactors, it uses up… Read more

Paralleling and ferroresonance as special problems with transformers
Occasionally, crews must install distribution transformers, either at a changeover or for extra capacity. If a larger bank is being installed to replace an existing unit, paralleling transformers during the changeover eliminates the customer interruption. In order to parallel transformer… Read more

Guidelines for good consumer unit design and low electric fields in the house
The consumer unit is the “fuse box” which goes between the electricity meter and all the electrical circuits in the house. Modern units do not contain fuses, but miniature circuit breakers (MCBs) which have replaced them. They often also contain… Read more

Best practice for using surge protective devices (SPDs) and RCD together
Where the power distribution system incorporates RCDs transient activity could cause RCDs to operate and hence loss of supply. Surge protective devices (SPDs) should wherever possible be installed upstream of RCD to prevent unwanted tripping caused by transient overvoltages. Where… Read more
