Your transformer should have a namplate on it that states how many amps or fractions of amps it can produce. You would then multiply that number by your secondary voltage to get your VA rating. sec. voltage 12v X .05 amp = 12 X .05= .6va

How many watts does a 22VA transformer have?

A 22VA transformer has a power rating of 22 watts. VA (volt-ampere) is a unit used to measure the apparent power in an electrical circuit.


What does 40 VA mean in a transformer?

In a transformer, 40 VA refers to the apparent power rating of the transformer. VA stands for volt-ampere, which is a unit used to measure apparent power in an electrical circuit. A transformer with a rating of 40 VA can handle a maximum apparent power of 40 volt-amperes, which is the product of the voltage and current it can handle. This rating is important for determining the capacity and suitability of the transformer for specific applications.


Can 24v 40va be used for24v 1 amp?

Yes, a 24V 40VA transformer can be used for a device that requires 24V 1A. The VA rating (volt-ampere) is a measure of the overall capacity of the transformer to deliver power, so the 40VA transformer has the capacity to supply the 1A required by the device.


What is the current carrying of an 1000kVA transformer?

You cannot answer this question without knowing the rated secondary voltage. Once you know this, divided the voltage into the volt ampere rating.


What is mean KVA Rating of transformer?

copper loss is directly propostional to I (AMPERE) and iron loss directly propostional to V (VOLTAGE) then total losses is equal to volt ampere hence the rating of transformer in KVA. SULTAN


Volt ohm ampere and watts are terms associated with what?

ohm is used to measure resistance of electric current. Ampere is used to measure electric current. volt is used to measure voltage.


What is the same on both sides of any transformer?

frequency. KVA is also same in both side of a transformer!!! KVA means Kilo Volt Ampere.


The unit to measure current is the volt?

The unit of current is the ampere. The unit of potential difference, or electromagnetic force is the volt.


Why is the rating of transformer in kVA?

kVA is essentially power rating (capacity) of a transformer. Since power is equal P=I*V, so P=kV*A, with I measure in Amps or denoted as A.AnswerA transformer's iron losses depend on the magnitude of the flux which, in turn, is proportional to voltage, while its copper losses depend on the winding currents. As both iron and copper losses contribute to the maximum operating temperature of the transformer, it follows that a transformer must be rated in terms of voltage and current. In alternating current systems, the product of voltage and current is apparent power, expressed in volt amperes.As a transformer's secondary voltage is kept approximately constant, it is its 'volt ampere' rating that determines its maximum (secondary) load current.Expressing a transformer's rating in watts (i.e. true power) would be completely meaningless because, with a highly-reactive load, it will be supplying practically zero watts while still having to supply its rated current.


What is the full load loss of a 630 kilo volt ampere and primary voltage is 11000 VOLT and secondary voltage is 440 VOLT of a distribution transformer?

That type of transformer normally has about 99% efficiency so the full-load loss would be 1% or 6 kW.
