 To adjust the component’s tolerances:
1. Double-click on the placed component and click the Value tab.
2. Change the following values as desired:
•
Animation Delay Factor — increase this number to slow the speed of animation of the
symbol blowing. This is not a real-time value.
•
Resistance — set as desired.
•
Maximum Rated Power (Watts) — If this value is exceeded during simulation, the
resistor blows.
•
Tem pe rat u re — set as desired.
•
Temperature Coefficient 1 — set as desired.
•
Temperature Coefficient 2 — set as desired.
•
Nominal Temperature — set as desired.
3. Click OK.
2.2.16 Rated Transformers
The transformer is one of the most common and useful applications of inductance. It can step
up or step down an input primary voltage (V1) to a secondary voltage (V2). The relationship
is given by V1/V2 = n, where n is the ratio of the primary turns to the secondary turns.
Note Refer to the Component Reference Guide for a more detailed discussion of
transformers.
