Error in SEL distance relay load encroachment simulation

We had discovered that OneLiner simulation of SEL distance relay setting NLAF (negative angle of forward load encroachment region) was not done correctly. This error could cause the program to report relay trip in correctly in some cases.

This issue had been fixed in OneLiner version 14.5 with build number 43533 and higher (Program version and build number are displayed in OneLiner Help | About dialog box).

Users should contact ASPEN support to request program update with the bug fix.
