The per unit system is a method of normalizing and simplifying the representation of electrical quantities in power systems. • This Tutorial shows the process of finding the per unit impedance values of an Electrical Network. • Doing a per unit system calculation is very important for finding your short circuit current. • It is commonly used in power system analysis and design to express the magnitudes of various electrical parameters in a consistent and dimensionless manner. The per unit system is particularly useful for comparing and analyzing different components within a power system without being concerned about the specific voltage or current levels. • All Electrical components on a network can be represented with an impedance value in per unit form that is the percentage form, this help a great deal to determine the value of the short circuit current. • Explore per-unit system calculations in electrical engineering with this comprehensive tutorial. Tailored for students, engineers, and professionals, this video covers the fundamentals of per-unit systems, including the importance of standardizing electrical quantities and the principles behind per-unit calculations. • Learn how to convert electrical values to per-unit equivalents, understand the formulae for impedance, voltage, and current transformations, and explore practical applications in power system analysis and design. Mastering per-unit system calculations is essential for ensuring consistency and efficiency in electrical engineering practices. • #perunit #powersystem #shortcircuit #fault #substation #mva #transformers #generator • Typo @5:55 The correct values are: Vbase(old) = 1000V and Vbase(new) = 800V • 01:00 - Zone 2 Line per-unit • 05:00 - Transformer T2 per-unit • 08:50 - Zone 3 Load per-unit • 18:50 - Impedance diagram and summary • 🔧 What You’ll Learn: • Basics of Per-Unit System in Electrical Engineering • Conversion Methods for Impedance, Voltage, and Current • Practical Examples and Case Studies • Applications in Power System Analysis and Design • 💡 Support the Channel: Knowledge Sharing • Help us create more in-depth tutorials and exclusive content by joining our channel membership or supporting us on Patreon.
