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.

Inevitable in almost all electrical switchboards – Residual current device (RCD)
Technology that RCD uses is so simple and so magical. The residual current device continually measures the difference between the value of the outgoing and incoming currents in the circuit it is protecting. If this difference is not equal to… Read more

Maintenance
The art of transformer maintenance, inspection and repair (recommended practices)
The primary purpose of transformer maintenance is to ensure the internal and external parts of the transformer and accessories are kept in good condition and “fit for purpose” and able to operate safely at all times. A secondary and equally… Read more

Advice in choosing the right neutral earthing system for your installation
The choice of a neutral earthing system is dependent on requirements and objectives that are often contradictory to such an extent that sometimes several systems have to be created within one installation (islanding) in order to meet safety, maintainability, or… Read more

Eight criteria you should consider when choosing the right MV/LV transformer type
Although there are few common-sense rules that every electrical engineer follows when choosing the transformer type, it’s always a good idea to name the most important of them. This technical article will briefly explain the eight most common and essential… Read more

Connections and composition of LV/MV/HV capacitor banks
Compensation capacitors are installed in numerous locations in electrical installations. They are to be found in high voltage transmission and distribution systems, in transformer substations and also at various levels in low voltage installations. Capacitors therefore have to be made… Read more

Medium Voltage
IEC and NEMA/IEEE ratings of current transformers (CTs) in medium voltage applications
First, let’s remind ourselves of the basics in a few sentences. That is something you must know. A current transformer (CT) is designed to produce a secondary current which is accurately proportional to the primary current. It consists of a… Read more

The problem of induced voltages in control cables in high voltage substations
Cabling in power substations is very important due to the fact that they are the longest parts of a system and therefore act as efficient antennas that pickup and or radiate noise. In HV substations, there are different kinds of conductors… Read more
