This feature allows users to merge two EA-PSM schemes into one. First of all, open the scheme which you want to append into:
Then select File → button, “Open file” box will pop up. Select the scheme which you want to append (i.e. Figure 5.2 ) into the currently opened scheme and click “Open”. When file is chosen, a grey rectangle will pop up, which shows new scheme’s area. The rectangle will follow the mouse cursor's movement, allowing the user to position the new scheme.
By clicking left mouse button, user will put appending scheme into the main one. Once the appending scheme is inserted, user may connect the schemes with a line or transformer based on voltage levels and the actual (real) connection between schemes.
