Knowledge sharing by *AAROHI* Today's topic: *What is harmonics for the electrical system & and from what source is it generated ( Part-1)* In simple terms, harmonics refer to additional musical tones that can be heard along with the main or fundamental tone. These tones are usually higher in pitch and blend together to create a richer, more complex sound. The same way In electrical terms, harmonics are additional frequencies that can be present in an electrical system, apart from the fundamental frequency (usually 50 / 60 Hz in many other parts of the world) These extra frequencies can be multiples of the fundamental frequency and may result from non-linear loads, like computers or electronic devices, Inverters connected to the power system. Harmonics can cause issues in electrical systems, leading to increased heat, reduced efficiency, and potential equipment malfunction. Managing harmonics is important to maintain the reliability and performance of the electrical infrastructure. *To be continued* ...... Have a great day ahead.... 🙏🙏🙏🙏

Learn the essentials of transformer connections – vector groups. The course starts with the vector and phasor basics and their difference. What phase shift and phase angle are and how phase shift is created in a transformer are covered in detail in the following lessons. The course consists of 15 lessons and 1h 26 min. total duration. You will learn why transformers are connected to form specific vector groups, the delta and star connections, and the relationship between line and phase voltages and current. What are the advantages and disadvantages of connecting transformer winding in Star or Delta? The answers are covered in great detail. We will discuss the 26 MVA transformer nameplate. The course continues with defining vector group dy11, clock method, lead and lag concepts. Finally, you will learn to draw vector group and connections of dy11,dy1, yd1, yy0,dd0, yy6, and yz1 configurations.

I have a blog where I explain how electricity works using some basic math and tangible examples. Check it out if your interested in this stuff!

It is quite exciting explaining the basics of power electronic converters to my students in the course "Frequency Stability and Control in modern power systems" in Arequipa, Peru. Students used the Virtual HIL from my colleagues and friends of Typhoon HIL to see the performance of the grid following the converter. I am sorry for my very ugly handwriting on the whiteboard. #Relphie provide very strong support and he liked the Peruvian coffee. #digitalrealtimesimulation #realtimesimulation #powersystems #frequenccontrol #frequency #frequencycontrol #frequencyprotection #protectionsystems #relaying #powerconverter #lowinertia #netzero #energystransition #MSs #UNSA #digitalinertia #einertia #inertiaresponse #BESS #EV #lowcarbontechnology

🌟The vector group refers to a notation used to describe the phase relationship between the primary and secondary windings of a transformer. It helps in understanding how the transformer will behave under different operating conditions, particularly in terms of voltage regulation and phase shifts. Let's decode Dyn11. "Y" for a star (wye) connection. "D" for a delta connection. 🌟The first letter, 'D', represents the connection type of the primary winding, and the second letter, 'y', represents the connection type of the secondary winding. 'n' represents winding grounded. 🌟The numbers '11' represent the phase shift between the primary and secondary windings. This is usually expressed in terms of clock-hour positions. 🌟 Powerup Series - Mastering Transformers 🌟 📅 Date: 05th May 2024 🕰 Time: 06:55 PM IST 🌐 Platform: Zoom Speaker: Er.
