Issue in OneLiner simulation of SEL distance relay directional element

ASPEN Support
Jul 9, 2019
1 min read

We found that the program did not correctly calculate the directional element of distance relay types: SEL311P__, SEL311G__, SEL421P__, SEL421G__, SEL411P__ SEL411G__ when the value of the E32 setting is AUTO.

This error had been fixed in OneLiner version 14.7 with build number 58027 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.
