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.

Lightning Protection System – Germany Regulations
The purpose of a lightning protection system is to protect buildings from direct lightning strikes and possible fire, or from the consequences of the load-independent active lightning current (non-igniting flash of lightning). If national regulations, e.g. building regulations, special regulations… Read more

The Rheostat In Few Simple Words
A variable resistor can be made from a wirewound element, rather than a solid strip of material. This is called a rheostat. A rheostat can have either a rotary control or a sliding control. This depends on whether the nichrome… Read more

Starting Motor With Auto-transformer
An auto-transformer starter makes it possible to start squirrel-cage induction motors with reduced starting current, as the voltage across the motor is reduced during starting. In contrast to the star-delta connection, only three motor leads and terminals are required. On… Read more

Torque Of Three-Phase Induction Motor Explained
The rotating force that a motor develops is called torque. Due to the physical laws of inertia, where a body at rest tends to remain at rest, the amount of torque necessary to start a load (starting torque) is always much greater than… Read more

Sources and Contributors To Short Circuit Current
Every electrical system confines electric current flow to selected paths by surrounding the conductors with insulators of various types. Short circuit current is the flow of electrical energy that results when the insulation barrier fails and allows current to flow… Read more

Working principle of thermal motor protection relay
Thermal motor protection relays contain three bimetal strips together with a trip mechanism in a housing made of insulating material. The bimetal strips are heated by the motor current, causing them to bend and activating the trip mechanism after a… Read more

Transformer Routine Test – Measurement of Voltage Ratio and Check of Phase Displacement
The no-load voltage ratio between two windings of a transformer is called turn ratio. The aim of measurement is: Confirming the no-load voltage ratio given in the customer order specifications, determining the conditions of both the windings and the connections… Read more

Transformer Routine Test – Measurement Of No-Load Loss And Current
The no-load losses are very much related to the operational performance of a transformer. As long as the transformer is operated, these losses occur. For this reason, no load losses are very important for operational economy. No-load losses are also… Read more
