Creating the Bergeron model 24

Testing the Bergeron model • Line Model Frequency scan. Model OK for 50 Hz. 25

26 Line Check • The user selects a group in the circuit • ATPDraw identifies the inputs and outputs (user modifiable)

27 Line Check cont. • ATPDraw reads the lis-file and calculates the series impedance and shunt admittance
