How do I find out the loading factor of a UPS on the power supply?

We own a 90 KVa UPS system. We draw only more or less 15 KVa power from the UPS to meet our wants. Our premises has a 250 KVA supply, what is the nouns of the UPS on the supply. Is it 90 KVa or 15 KVa?

How do I find out the loading factor of a UPS on the power supply?

Just follow the link.
90 at the most and with the sole purpose if it is completely flattened in use. 'cos the UPS will lone draw what it needs
How did you trade name the assumption that you draw only 15KVa

power from the supply.



I infer that suppose you hold installed say some 270 computers assuming 3computes per kva and you are

switching on lone 45 computers then the nouns on the

power supply will be 15kva under absolute conditions like



1. assuming an online ups the current needed to charge

the battery.

2. the load factor is also dependent on the existing charge

on the battery.

3. some ups have a speedy charger then the nouns will be

marginally higher.



but if largely the noload factor(no computers switched on

only the ups is switched on) is specified then it will be

easier to subtract the loading factor.\





A crude method would be if you have a unswerving electricity

board meter then you can switch on the ups (no load)

take in the meter reading.

Then switch on computers gradually increasing the nouns

and observe the meter reading.



An easier method would be using a tong tester calculate the

amps flowing through the power cable under different

nouns conditions and calculate watts. :-)
