I work for municipal that distributes electrical power. Voltage is 12,470 phase-to-phase. Understanding/calculating transformer inrush for a single transformer is pretty straightforward -- 12X rated load for 0.1 second.
We have fused sections of distribution where the connected transformer...
A practical question:
What is the most common short circuit rating of 120/240 volt service panels for 100 amp, 150 amp and 200 amp services? What should be done if the available short circuit exceeds this rating?
