Assumption:
F= 60Hz
V= 1v is equal also to I=1amp.
PF= 0.85
Single Phase: Three Phase:
S = IV pf / 1000 S = 1.73 x I x V x PF/1000
= 1 x 1 x 0.85/1000 = 1.73 x 1 x 1 x 0.85 /1000
S = 0.00085KVA S = 0.0014705KVA

How do you calculate the output voltage of a transformer if kva rating is known?
You can't determine the output voltage of a transformer by knowing kva. Transformers will be marked as to input and output voltages. Some will have multiple input and output voltages. The output voltage depends on the ratio of coil turns between input and output.
What is the formula to calculate load voltage?
Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula. KVA = Volts * Amps / 1000
What is the kva for 138kv?
KVA is a measurement of power; kV is a measurement of voltage. You're asking "What is the power for voltage?", which makes no sense. Power = Voltage times current.
200 amp equals how much kva?
200 amps is equal to zero kva. To answer this question a voltage is needed.
What are three requirement for connecting the transformer in paralle?
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
How do you calculate kva from amps?
At what voltage? If you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
How do you calculate KVA when you know amps and voltage required?
Use the link below and scroll down.
How do you calculate the voltage that has to be kept for a 150 KVA solar power conditioning unit?
The voltage is not 'calculated', it's determined from the specifications of the unit you are going to use.

What size wire 100 kva transformer?
Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
What is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage

What are three requirement for connecting the transformer in paralle?
Transformer capacity (kvA) shall be identical, Both transformer impedance, secondary voltage and frequency shall be identical.
What are primary parameters of power transformers?
Input and output voltages, maximum current rating, often expressed in VA or kVA as the voltage rating times the current rating. Operating frequency is the next important parameter because if the frequency is lower, the voltage must be reduced in proportion.
Two and an half kva equals how many ampere?
2.5 kVA means 2500 VA (volt-ampere). To calculate the amperes you need the voltage. 2.5 kVA x cos (phi) = 2.5 kW (kilowatts) if phi is 0 or power factor (phi) is unity.
