Apparent Power Converter

Do you own a stabilizer in your house? Well, a transformer works as a barrier between the appliance and the electrical source if you have a refrigerator. It then maintains the output voltage to keep it stable during brownouts. We can obtain the transformer rating by installing the stabilizer between the voltage supply and the refrigerator. Your electricity bill, for example, includes active power spent, but reactive power is free. However, the fitted stabilizer also accommodates reactive power, making up the apparent power and determining the transformer's rating.

Apparent power is a product of reactive and real power and is used to calculate transformer MVA rating. When the impedance is a pure resistance to an electric circuit or component to alternating current, the true power is the same as the apparent power. Reactive power, on the other hand, is the difference between perceived and genuine power when reactance exists.

How to calculate apparent power?

VA is the unit of apparent power computed by multiplying input voltage by input current or output voltage by output current.

S(MVA) = I(Primary) x V(Primary) / 1,000,000 where 

I(Primary) denotes the primary current in amps.

V(main) is the primary voltage in volts.

S(MVA) is the product of primary current and voltage divided by one million.
