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.

Where and Why Do We Use Grounding Transformer (zig-zag, grounded wye-delta)
Grounding transformers are sometimes used on distribution systems. A grounding transformer provides a source for zero sequence current. Sometimes they are used to convert a 3-wire, ungrounded circuit into a 4-wire, grounded circuit. Figure 1 (see below) shows the two most common grounding transformers. The… Read more

Where Do We Use Arc Suppression Coil (Petersen Coil)?
The arc suppression coil (ASC), also known as Petersen coil, is used to compensate the capacitive earth fault currents supplied by outgoing feeders at a substation. The compensation can be either centralized or distributed. With the centralized design, one ASC… Read more

Tips For Successful Energy Efficiency Of Centrifugal Water Chillers
Centrifugal water chillers comprise a significant portion of industrial and large commercial electrical load. These machines are efficient, typically producing a cooling effect two-to-three times greater than the required energy input. Centrifugal water systems were the focus of cholorfluorocarbon (CFC)… Read more
