who knows 30kva means 30000 volts per ampere so if the output is 100 volts the amps will be 300 amps so do the math.

What is the breaker size for a 10 KVA electric heater?
What size breakers are needed for a 30kva transformer 208 volt feed 600 volt out put
Can 2 transformers of 30KVA 60 Hz run 100 kw machinary?
Think about it. Assuming a total transformer capacity of 60 kV.A, how could it possibly supply a load of 100 kW?
How many 16 Amps per phase welding outlet can you install to a 30 KvA rating transformer?
..the questions does not say wether the 30kVA transformer is 3 phase transformer or single phase transformer..but it is implying that a single phase welding load at 16A per phase is to be connect to it, it is assumed then that the transformer is 3 phase transformer..we assume load is rated 240V.. ..though not much details is given about the transformer voltage specs. but if is rated 3 phase 415/240V, the approx full load current per phase is given by 30KVAx1.3912=41.736A.. ..but if the transformer was rated single phase 240V say, the approx full load current FLC=30000/240V gives 125ampers.. ..if you further devide the FLC by the intended load current.. ..Recommended no of welders per for a 3 phase 415V transformer and assuming single welding sets =41.736/16=2.6..so you can connect max two welding sets to this transformer per phase,..max 6 weld sets can connect at an approx load factor of 76%.. ..for the single phase transformer, FLC/16=125/16, gives 7.8 but is also recommended not to connect more than 6 welding sets to such transformer for the same reasons..
What is the importance on transformer utilization factor?
Ulitization factor is how much of the designed total is used. My house is fed off a 50KVA transformer. It's capable of supplying 50KVA continuously, but it's probably only gets used at its' full potential every once in awhile (when my neighbors and I wake up in the morning, and when we get home from work and eat dinner, perhaps). Say it only gets used at 30KVA on average. The utilization factor would be 30/50, or 60%.
What kilowatt of AC generator will drive a 18 kilowatt ac motor?
30kva generators ,it can be able to run the 18kw ac motor
How many amps can 30 kva transformer 575 volts to 480 volts gives?
for three phase the calculation is 30,000 = 1.73*V*I - simple as that. For single Phase the calculation is 30,000 = V*I - simple as that It is important to note the voltage in the first line is Line to Line (typically how it is specified in three phase power systems), and the second line it is Line to neutral. A 30KVA transformer is the same as 30,000VA to find out the Amps you need to divide the voltage if the transformer is single phase for example: 30,000VA / 480V = 62.5 Amps The calculation for a 3 phase transformer is the VA / voltage / 1.73 for example: 30,000VA /480V / 1.73 = 36.12 Amps

How does a computer's UPS work?
It is a secondary battery it stores enough power as in case of yr emergency lamps and utilise it later. UPS is for the purpose to give un-interruptible power supply. This stores the energy in the form of DC by the controlled rectifier (AC - DC converter) and discharge the energy in the form of controlled AC by inverter (DC - AC converter) so as to provide continuous power supply. Here the back up is derived based on the requirement. types: 1. Online Double convertion UPS (Normal High capacity UPS) 2. Online Delta convertion UPS (New technology offline using buck boost Transformers) 3. Offline UPS (economical UPS medium capacity UPS 3 - 30KVA also available in higher capacity) 4. Line Interactive UPS (lower capacity UPS 300VA - max5KVA output will be Squasi Sinewave). UPS are used in home, medical, IT and industrial where the critical load is used.
