I have an old relay settings file that is referrring to the 'Winter DAL'rating (given as 32MVA) and has the Inverse Time-overcurrent element pickup set above it. Can someone explain this a little bit. I searched online and I saw apost saying that you shouldnt load the line for more than 5 mins ovee the DAL rating. If that's the case, then why is the ToC element set ABOVE the rating?
