Just out of interest and peace of mind for yourself, next time you chat to the Sandont CC guys, would you mind finding out what their available 3-phase power capacity is to you?Originally Posted by Blaze786
Power is our main concern, we are using the sandton convention centre and they have a 3 phase system, from what I have been told power will not be a problem
I'd like to run some numbers to see if you're covered.
Keep this in mind...it's pretty standard practice for a convention centre to have backup power...however as with most installations, the backup gennies do not cover the entire facility and your boards are divided up into normal / Standby & UPS supplies.
So you have 2 scenarios:
1) Mains power fails on that day. Result: Only essential services boards have power. Depending on their layout, 40% of your power might be gone. Even if by some chance the entire facility is supported, you now face running time VS Diesel costs. Those big gennies will drink diesel faster than you'll know what to do with yourself.
2) The facility's power is insufficient. Result: Circuits trip from overloading. No way around this but to reduce load after balancing phases. To avoid mass phase failures, you'll have to sub-divide clusters of people to localize faults.
I really like what you're doing, but as you can see my interests lie in the technical side of it.
