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.

How heat pump works?
The heat pump transfers the heat between the heating/cooling distribution system and the earth connection. It is the basic building block of the GSHP system. The most common type of heat pump used with GSHP systems is a “water-to-air” unit… Read more

Renewable Energy
Stand-Alone PV Systems
Stand-alone PV (photovoltaic) systems are used when it is impractical to connect to the utility grid. Common standalone systems include PV-powered fans, water pumping systems, portable highway signs, and power systems for remote installations, such as cabins, communications repeater stations,… Read more

How to determine the hydropower available at site
To determine the power available at a site, head and flow measurements must be taken. Flow is the rate at which water moves, measured in liters per minute (I/m) or gallons per minute (gpm). This can be measured by channeling… Read more

How contactor controls an electric motor?
When a relay is used to switch a large amount of electrical power through its contacts, it is designated by a special name: contactor. Contactors typically have multiple contacts, and those contacts are usually (but not always) normally-open, so that… Read more

Wind Power
Integrating wind energy into the electricity network
One of the most frequent misunderstandings occurring in the public discussion about integrating wind energy into the electricity network is that it is treated in isolation. An electricity system is in practice much like a massive bath tub, with hundreds… Read more

Transformers
GEAFOL – cast-resin transformer
The Siemens’s transformer GEAFOL principle has succeeded in producing transformers with excellent electrical, mechanical and thermal characteristics, which have also proved to be particularly compatible with the environment. GEAFOL transformers are insulated with an epoxy resin/quartz powder mixture. This is… Read more
