I am an electrical engineer that needs a little HVAC help. The guys I know hadn't done this before. I have a medium voltage generator control switchboard which utilizes resistors to disipate heat generated in case of a ground fault. My system is 2400/4160/3ph. The resistor can sustain 400 amps for up to 10 seconds. The calculated energy I need to dissipate is 960,000 watts which can be generated for up to ten seconds. Thats about 3.3 million btuh for ten seconds. Can anyone tell me the associated rise in the adjacent area? The resistors consist of stainless steel bars with ceramic insulators in a stainless ventilated enclosure on top of a switchboard in a room that's 60'x40'x 24'high. Oh yeah, there's a couple of 1000kw Generators and their silencer's in there too. But I am just concerned with the area around the resistors. How hot is it going to get? Any clues? Any help is appreciated. Thanks
