1758 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.

Protection
Using earth & phase directional protection where power flow direction might change
Directional protection relay is often used in all network parts in which the direction of flow of power might change, notably in the instance of a short circuit between phases or of an earthing fault (single phase fault). Directional protection… Read more

Energy Generation
Typical electrical distribution scheme and SCADA system of an oil/gas production plant
Power can be provided from mains power or from local gas turbines or diesel generator sets. Large facilities have high power demands, from 30 MW and upwards to several hundred MW. There is a tendency to generate electric power centrally… Read more

Fire behaviour and construction safety precautions for installation of cables and conductors
Although the type of cable and conductor is the determining factor in the fire behaviour of ducts and conduits, the choice of cable tray type and the installation of the latter in line with installation precautions are just as crucial…. Read more

Protection
What is the unit protection and why it’s widely used in transmission networks
The whole power system must be protected. This is achieved by dividing it into overlapping zones. If a fault occurs in a particular zone, only the protection system covering that zone should operate. Those systems relating to other zones should… Read more

Integration of IEC 61850 in power plant automation, control, and protection systems
IEC 61850 is much more than a protocol. The general scope of the standard is designed to support the communication of all functions being performed in a substation. Its main goal is interoperability and this is the ability for IEDs… Read more

Protection and control logic: Optimize it, but don’t complicate
This technical article discusses some of the basics of protection and control as successfully used for decades. Majority of these general requirements will have to be retained by new communication-based solutions. It is important to distinguish between the key need,… Read more

The theory behind reactive energy compensation that every engineer should know
Reactive energy compensation is an essential process in improving energy efficiency. It reduces the power consumption and thus its cost, enables optimum use of installations by preventing them being oversized, and more generally it improves the quality of energy systems…. Read more

Six tools you MUST learn before programming numerical protection relays for real
Developing basic setting specifications for numerical relays is a boring process for most electrical engineers, but not for the protection engineers! It requires significant input data but, for the most part, is exciting and relatively straightforward. A basic understanding of…...

The case of phase-to-phase fault in a 13.8 kV switchgear caused by heavy rain
In this case study we describe a 13.8 kV switchgear phase-to-phase fault due to by heavy rain evolving into a three-phase fault that was cleared by transformer numerical relays. The generator was out of service and the fault was fed…...
