Respected sir, |
I want to know about my own distribution transformer design some given red value are I know, but I am not sure my design is correct. |
| How can it be rechecked? The design which is make by me give the output good. | But I am already check the design by FORMULA |
| Q = Rating of t/f in kva = | (3.33x f x Bm x δ x Kw x Aw x Ai )/1000 in given formula I am no know the Aw what value filled .so please tell me |
| How can recheck the output of transformer in kva is right. What figure to be match with each other or equal to when I am cross check of my design |
| all data given below in which we cross checked it :- |
| KVA | 16 | 11000/433V |
| δ | CURRENT DENSITY-A/mm2- ----LV | 2.304 | A/mm2 |
| Ai = | 0.0046 |
| Kw = | 0.0111 |
| frequency | 50.00 | Hz |
| FLUX DENSITY-TESLA = | 1.554 |
| NO OF LV TURNS = | 156.0 |
| WINDOW HEIGHT-mm = | 205.00 |
| CORE CENTER-mm = | 179.89 |
| STRIP size bare = | 4.05 x 2.40mm |
| Wire size Bare = | 0.560mm |
| CORE DIA- | 81.6 | mm CL | 179.89 | mm |
| KVA | 16 | W/H | 205.00 | mm |
| Sr No. | STACK | THICKNESS mm | AREA |
| 1 | 75 | 32.10 | 2407.61 |
| 2 | 70 | 9.80 | 685.81 |
| 3 | 60 | 13.38 | 802.67 |
| 4 | 55 | 4.98 | 273.74 |
| 5 | 50 | 4.21 | 210.48 |
| 6 | 40 | 6.64 | 265.55 |
| 7 | 30 | 4.76 | 142.89 |
| Total | = | 75.87 | 4788.75 | mm2 |
