Equation for finding current

WebThe full load current for a 3-phase generator specified in kVA is calculated as: Where, S va is the generator rating in kilo-volt-ampere (kVA). V LL is the generator line-to-line rated voltage in volt (V). For example, calculate the full load current of a 50 kVA, 480 V, 3-phase generator. . I = 60.1 A. WebSep 12, 2024 · From the right-hand rule, the magnetic field d→B at P, produced by the current element Id→l is directed at an angle θ above the y -axis as shown. Since d→l is parallel along the x -axis and ˆr is in the yz -plane, the two vectors are perpendicular, so we have dB = μ0 4π Idlsinπ / 2 r2 = μ0 4π Idl y2 + R2 where we have used r2 = y2 + R2.
