Petrochemical industry, two UPS dual-machine hot backup power supply for the instrument, this part of the load how to calculate the need to account for the total capacity of the load?
UPS for the instrument power supply need to join the load!
Double machine is hot backup, the capacity of each machine should be greater than the total capacity, otherwise it will lose the role of hot backup.
No, what do you mean when the UPS is powered by the load, and then calculate the total load when you add the UPS capacity to the load?
Can not be calculated, UPS is only the transmission part of the electricity, UPS own load should be (1 - output power) * UPS capacity
