3 Phase Auto Transformer Calculations. Hence the nearest available size of the fuse is 710Amps. Auto Transformer winding diagram Transformation ratio k is equal to the ratio between secondary output voltage V 2 in Volts to primary input voltage V 1 in volts or ratio between primary current I 1 in amps to Secondary output current I 2 in amps or the ratio between secondary turns N 2 to primary winding N 1. Electrical Conductive Transferred kVA P. Then each corresponding secondary winding will then have this same voltage induced in it and since these windings are delta-connected the voltage 1 3 V L will become the secondary line.
V k x 1000 A x Ph A k x 1000 V x Ph k Ph x V x A 1000 Where V Volt A Amps k kVA Ph 3 phase 3 1732050808 Example. V x I 1000. Therefore 250kVA transformer can be charged with the 710A fuse. Find kVA Current And Windings for 3 Phase Transformers February 21 2021January 1 2019 by Electrical4U The ideal transformer equation relates to the primary and the secondary voltage Vs Vp Ns Np. This comes useful when the supply voltage or line voltage available to you does not match the input voltage requirements of the device you want to operate. The primary current can be computed by using the same formula that was utilized to calculate primary current for an isolation sort of transformer.

I personally designed and used it. V k x 1000 A x Ph A k x 1000 V x Ph k Ph x V x A 1000 Where V Volt A Amps k kVA Ph 3 phase 3 1732050808 Example. Therefore 250kVA transformer can be charged with the 710A fuse. The transformer calculator uses the following formulas. This comes useful when the supply voltage or line voltage available to you does not match the input voltage requirements of the device you want to operate. Hence the nearest available size of the fuse is 710Amps.
