10.4 SP2 Release Notes

EasyPower 10.4 Service Pack 2 includes the following bug fixes.

Arc Flash

  • The Open Air 70E 2009 Annex D8 method was using 3-phase fault type multipliers for single-phase buses. Single-phase arc flash no longer uses multipliers from the Advanced Arc Flash Options.

  • The downstream protective device is shown as the main device on the Arc Flash Hazard report when calculating arc flash using the Momentary method and the Output is set to Including Main. With the fix, protective devices with currents less than 1 Amp are ignored by default.

  • The program terminates unexpectedly without displaying an error message while attempting to run an arc flash analysis.

  • The lower limit voltage for arc flash method IEEE 1584 2018 was removed to display arc flash results for less than 208V while using the Momentary method.

  • Incorrect results were given when using the Momentary method when the faulted out of range bus kV <208V and current >65 kV and <106kA.

Connection Data

  • The phase connection data does not get set properly on an LV breaker in an ATS.

  • The phase connection data does not get set properly to main breakers in panels.

Coordination

  • Plotting a TCC when the license does not include Short Circuit caused the program to terminate unexpectedly.

  • The TCC for ATS breaker curves do not shift based on the reference voltage in a single-phase TCC plot.

  • The program detects an internal issue while inserting an existing item into a TCC one-line.

Database Files

  • Unable to save files due to a generic DLL error. To resolve this issue, temporary files that the program creates are stored in the user's Documents folder (for example, My Document/EasyPower 10.4/Temp).

Panels/Schedules

  • Incorrect total VA values in the code factor table in the schedules for single-phase panels.

  • Load amps are incorrect for 2-pole circuits in the Simplified view on a panel when converted from VA.

Short Circuit

  • The program displays an unhandled exception message while printing or exporting the LV Interrupting report using the GE format.

  • An incorrect unit is showing on remote DC branches in IEC, displaying kV instead of kA, MVA, or PU.

  • Zero fault current is displayed for a DC motor when faulting a DC bus.

  • Remote voltage is displaying zero on a single-phase AC bus while faulting a DC bus on the rectifier side.

  • An incorrect DC remote bus voltage is displayed on the one-line.

Tabs

  • When tabs are enabled in Tools > Options > General, the user should not be able to edit the Tab Location text directly.

Translation

  • This release includes documentation updates for the Spanish, Portuguese, and Chinese versions of EasyPower.
