Model Equations and/or Block Diagrams

Parameters:

NoTrip	No Trip Flag. Set to > 0 to disable breaker tripping. Note: relay signal will still update.
Shape1	Shape of Impedance Zone 1. 0 means a circle, lens or tomato. 1 means a rectangle
Shape2_Relay	Shape of Relay End Impedance Zone 2. 0 means a circle, lens or tomato. 1 means a rectangle
Shape2_Other	Shape of Other End Impedance Zone 2. 0 means a circle, lens or tomato. 1 means a rectangle
Shape3_Relay	Shape of Relay End Impedance Zone 3. 0 means a circle, lens or tomato. 1 means a rectangle
Shape3_Other	Shape of Other End Impedance Zone 3. 0 means a circle, lens or tomato. 1 means a rectangle
Tcb	Breaker Operating Time (in Seconds)
Ang1	Angle (in degrees) of Impedance Zone 1
Rf1	Forward Reach Impedance (in per unit) of Impedance Zone 1
Rr1	Reverse Reach Impedance (in per unit) of Impedance Zone 1. (Note: For backward reach, specify a POSITIVE number.)
Wt1	Total Width (in per unit) of Impedance Zone 1. If Width > Rf + Rr, then use union of circles (tomato). If Width < Rf + Rr, then use intersection of circles (lens). If Width = 0 or Rf + Rr, then just use one circle (circle).

Wt2_Relay	Total Width (in per unit) of Relay End Impedance Zone 2. If Width > Rf + Rr, then use union of circles (tomato). If Width < Rf + Rr, then use intersection of circles (lens). If Width = 0 or Rf + Rr, then just use one circle (circle).
Wr2_Relay	Right Width (in per unit) of Relay End Impedance Zone 2. (Only used for rectangular shape)
T2_Relay	Pickup Time (in Seconds) of Relay End Impedance Zone 2
Ang2_Other	Angle (in degrees) of Other End Impedance Zone 2
Rf2_Other	Forward Reach Impedance (in per unit) of Other End Impedance Zone 2
