Cause : DC short circuit comes when closing the charging contactor, the voltage did not rise above 10% from nominal voltage in 0.2 seconds (can be set in service level), but the current rose above level set by parameter 120.22 Max current for MCB closing.
- There is a short-circuit in DC busbar.
- Check DC busbar.
