Error in the calculation of Unstable Power Swing Limit for phase overcurrent relays

We had discovered a calculation error in the Overcurrent Relay Curves window command Add | Unstable Power Swing Limit that caused the program to report the wrong result.

This issue had been fixed in OneLiner version 14.7 revisions with build number 62045 or higher (Program build number is displayed in the OneLiner Help | About dialog box). Users should contact ASPEN support to request program update with the bug fix.
