  • Why We Need Protection System? and What is Required from Protection Devices?14:46

    Understand why electrical power system protection is essential to protect equipment and ensure continuous power supply. Learn the basic requirements for protection devices, including selectivity, stability, and sensitivity.

  • Basic Protection Devices8:25

    Explore the basic protection components, including fuses, voltage and current transformers. Explain how relays trigger alarms and trips and how circuit breakers isolate faults.

  • Simple Distribution Systems10:07

    Compare radial distribution and two alternative feeds, showing how protection devices isolate faults and how a second cable maintains continuity of supply across two buses.

  • Different Types of Faults and Effects15:42

    Electrical power system protection covers active, passive, transient, and permanent faults, including phase-to-phase cases, and explains how overloading, overvoltage, and under frequency stress insulation.

  • Introduction to Short Circuit Analysis10:52

    Explore short circuit analysis in a radial distribution system, identifying the fault location, converting equipment to impedances, and calculating short circuit current using source and component impedances.

  • Fault Calculations - The Golden Equation11:32

    Learn to calculate short-circuit current and power on a radial power system using the golden equation, linking operating voltage, short-circuit impedance, and equipment ratings to determine percentages.

  • Fault Current Calculations - The First Method13:45

    Apply the first method to compute fault current using the transformer's percentage impedance. Relate short-circuit current to rated current and voltage with the three-phase formula.

  • Fault Current Calculations - The Second Method16:48

    Learn to calculate the short-circuit current with the second method by using base values, percent impedance, and transformer impedance to solve for fault current.

  • Minimum Time Required to Clear The Fault According to Short Circuit Level7:49

    Calculate the short-circuit current using the cable cross-sectional area and material constant k, then determine the minimum cable size and circuit breaker clearing time.

  • Power Fault Method - Part 116:35

    Learn to calculate short circuit current for each equipment in an electrical network and combine series and parallel results to obtain the short circuit current, with transformers, cables, and motors.

  • Power Fault Method - Part 214:12

    Learn to calculate total short-circuit power by combining generator, transformer, and cable impedances, then analyze faults at buses like PA and city hall and partition network into zones for protection.
