## A (50/60 Hz) Transformer. Which one will give more Output?

- Operates on 50 Hz
- Operates on 60 Hz

**Obviously!** It will give more out put when we operate a transformer (of same rating) on 50 Hz instead of 60 Hz.

*Suppose,**When Transformer operates on 50 Hz Frequency*

**Transformer = 100kVA, R=700**

**Ω**

**, L=1.2 H, f= 50 Hz.**

_{L}= 2πfL = 2 x 3.1415 x 50 x 1.2 = 377 Ω

^{2}+X

_{L}

^{2}) = √ (700

^{2}+ 377

^{2}) = 795 Ω

*Now,**When Transformer operates on 60 Hz Frequency*

**Transformer =100kVA, R=700**

**Ω**

**, L=1.2 H, f= 60 Hz.**

_{L}= 2πfL = 2 x 3.1415 x 60 x1.2 = 452.4 Ω

^{2}+X

_{L}

^{2}) = √ (700

^{2}+ 452.4

^{2}) = 833.5 Ω

*If we do the same (As above) for the power transformer i.e, for 500kVA Transformer, the result may be huge, as below.***JLCPCB - Prototype PCBs for $2 + Free Shipping on First Order**

Wrong unit in the last row!<br />440kW – 419.5kW = 20500W = 20kW

20500W … We assume that 20.5kVA = 20kVA … for calculation purpose only ….

How to calculate the induction value resistance value and amps value of transformer and how calculate the winding turns based on voltage

Thanks to give basic and extra knowlege.
