I'm trying to learn a little bit more about three phase current, power and KVA.
We currently have some hi-tech UPS power systems at work and I'm trying to ensure that they are adequately provisioned to cope with a power outage.
The UPS's are rated to about 200KVA.
For simplicity imagine that two distribution boards are connected to the UPS. Each distribution board is capable of recording the current of each of the three phases.
Switch Board 1
Switch Board 2
We are in Aus where the devices typically run at 230-240V. Take the higher voltage please 240.
How do I use the known currents of each phase and switchboard to calculate:
A) The KVA of Each switchboard
B) The Power of each switchboard in KW
Please show any calculations in the solution. If I'm missing any vital information please ask and I'll attempt to find out more.
