Event Navigation

Synopsis
A continuation of part one, this class builds upon the per unit system and takes you to the next level with symmetrical components and unbalanced power system calculations. Learn how to more easily use positive, negative and zero sequence components and draw zero sequence diagrams.

Description

Impedance Data, Geometric Mean Radius, Geometric Mean Distance, Capacitive Line Charging, Skin Effect

TRANSMISSION LINES
Short, Medium and Long Transmission Line Models, Voltage Drop, Sending End and Receiving End Voltage, Conductor Data a.k.a. “The Birds” Wax Wing, Blue Jay, Partridge etc.

MOTOR STARTING
Using the Per Unit System to Solve Motor Starting Problems, Voltage Flicker Analysis

SYMMETRICAL COMPONENTS
Positive, Negative and Zero Sequence, Zero Sequence Diagrams, Effect of Grounding on Zero Sequence Impedance, Solving Symmetrical Component Problems Painlessly! Transmission Line Problem and Examples, Solving Three Phase and Line-to-Ground Short Circuit Problems with Positive, Negative and Zero Sequence Impedances.

SHORT CIRCUIT CALCULATIONS
Ohmic and Per Unit Calculations, Symmetrical Component Calculations for Balanced and Unbalanced Faults

POWER FACTOR BASICS
