ransformer's formula
Transformer's formula
TVP=turns per volt (parti volt lapeto ki sankhya)
BMAX = The maximum magnetic force lines (Kilo per square Itch)
A=Core Area (Square inches) F=Frequency
108=The final number! Turns out the Volt is used!
4.44 (1.11×4)= The final number! Turns out the Volt is used!



1.     Watts out of secondary formula
V×A=W
2.     Formula to get the core area
√WS  (Secondary Wattage  )
5.58
3.     Primary wattage  extract formula
Primary wattage= 
           Secondary wattage (WS) ÷ Transformers work flexibility
4.     KVA primaries get formula
Primary AMP=primary wattage ÷ primary volt
5.     Turns out the Volt formula
108
                                                            1.11×4×Bmax×A×F
6.       Turns out the formula of total primary
Volts per turn × Primary Volt
7.       turns out the formula of total secondary
Volts per turn× secondary  Volt

For Examples
8.       220 volt primary and secondary voltage of 10 volts and a current of the transformer secondary wending Amperes formula 4!

First Secondary watts to know

10×4=40
Output volt amperes multiplied by the output of the output Wattage would know!

The core area is to know

√40÷5.58=1.133Sq  (5.58) fix number

Primary wattage to know

40×100÷90=44.4
Multiply 100 wattage give output, divide by 90 to get the number. Here has been so generally run from 90 to 90 percent of the transformer calculation functions are powered.


Primary amps to know
44.4÷220v=0.02018A    Primary wattage divided by the primary.

Turn the Volt to know!
                                                108÷1.11×4×60000×1.133×50=6.62

The total turnover of primary
220×6.62=1456.4 or 1460

The total turnover of secondary
10×6.62=66.2 or 66 tarn
