and the reactive power formula in both connections is: Q = √3 × Vline× Iline× sin φ ⚠️ Though we can use the same power equations for both three-phase systems, the line quantities are not the same. For example, if the phase voltage is 400 V, the phase current is 10 ...

According to the principles of three-phase theory, the line voltages can be expressed based on the phase voltages. Specifically, the voltage between phases \(a\) and \(b\), denoted as \({V}_{ab}\), can be calculated using Eq. (6), which states that it equals the difference between...

However, most of them do not comply with the standard definitions for the effective values of three-phase voltage and current. Furthermore, extensive investigations are not performed for the calculation of the decomposition factors in three- and four-wire three-phase systems. In this paper, ...
To find the rated current of the pump, use the formula I=P1.732×V×pf where P is 16 kW, V is 400 V, and the power factor (pf) is 0.75. Ans:) Power of the 3 phase motor, P = 16 kW Voltage supply, V = 400 V Power facto...
