Vary parameters, start simulation and export scope waveforms by script
Description:
This script is a simple example to learn how to script.
The script is started from the EMTP design by double clicking on the 'Script1' grey button.
The script example:

- varies a fault resistance
- runs a simulation for each value
- exports results of a selected list of scope in MAT and ASCII formats
- returns Min and Max
Tag(s): script, script, ASCII, MAT, parametric, minimum, maximum
DC component suppressor
Description:
This model suppresses the DC component in the measure of a fault current to keep only the permanent part.
AC and DC components meter
Description:
This example contains a device which calculates the DC and AC components.
- The DC component is available in the DC control scope with half
a cycle delay versus the simulation time
- ... see moreThe AC component is available in the DC control scope with one
cycle delay versus the simulation time
Once the maximum DC magnitude is reached, the time constant is
determined assuming the DC decay is exponential and uninterrupted
Tag(s): DC, AC, exponential, meters, zero-crossing, asymmetry, fault
Zero-crossing fault
Description:
This example provides a device which is a 3-phase bolted fault.
Once the simulation time has passed faultTime, the first phase voltage
crossing zero triggers the fault on the 3 phases simult... see moreaneously.

Fault on a line
Description:
This model is a faulty line. The distance of the fault from the origin is a parameter. CP or PI models are used on each side of the fault according to the time step. If the time step is small enough t... see moreo simulate the propagation in the line with at least 10 time steps, CP is used, else it is PI.
