Volt amperes are a unit utilized to describe the electrical load in engineering. Volt amperes can be abbreviated VA. You can also utilize metric prefixes such as "kilo-" and "mega-." It takes 1,000 volt amperes to rise to one kilo-volt ampere and 1,000,000 volt-amperes to equal one mega-volt ampere. Therefore, it takes 1,000 kilo-volt amperes to get one mega-volt ampere. Divide the number of kVA by 1,000 to convert to MVA. For example, in case you’ve got 438 kVA, isolate 438 by 1,000 to get 0.438 MVA

MVA stands for Mega Volt Amp or Volts X Amp /1000,000. In case your add up to load necessity is 1000 volts and 5000 amps (1000 x 5000 = 5000,000 VA) it can be communicated as 5MVA. Usually called "apparent power" since it takes into thought both the resistive load and the reactive load. We generally indicate load by MVA, KVA or VA as any specific appliance of power framework generally absorbs active power as well as reactive power. ( Eg: transformers).
Partition the number of kVA by 1,000 to convert to MVA. For illustration, in case you have got 438 kVA, isolate 438 by 1,000 to induce 0.438 MVA.Multiply the number of kVA by 0.001 to change over to MVA.
10 MVA = 10000 KVA

Transformer oil (moreover known as insulating oil) may be a uncommon type of oil which has fabulous electrical protection properties and is steady at high temperatures. Transformer oil is utilized in oil-filled electrical power transformers to insulate, stop arcing and corona release, and to disseminate the heat of the transformer (i.e. act as a coolant).

The impedance of a transformer is the entire restriction offered to substituting current. This may be calculated for each winding.However, a rather basic test gives a practical strategy of measuring the comparable impedance of a transformer without isolating the impedance of the windings.
Calculation of Percentage Impedance
In arrange to decide proportionate impedance, one winding of the transformer is short-circuited. And a fair sufficient voltage is connected to the other winding to make full load current to stream within the short-circuited winding.This voltage is known as the impedance voltage.

kVA stands for Kilovolt-Ampere and is the rating regularly utilized to rate a transformer. The size of a transformer is decided by the kVA of the load. In numerous circumstances the power required by the load is proportionate to the rating of the transformer communicated in either VA or kVA. For case a 1KW (1000 Watts) load would require a 1kVA transformer @ unity power factor.
KVA calculation
For three phase KVA= (V*I*1.732)/1000
For single phase KVA= (V*I)/1000
MVA calculation-
For three phase MVA= (V*I*1.732)/100,000
For single phase MVA= (V*I)/1000,000
