(1) the output of generatoractive power is reduced. (2) reduce the power supplycapacity of the transmission and transmission equipment. (3) increase in line voltageloss and power loss. (4) it causes low powerfactor operation and voltage drop, so that the capacity of electrical equipmentis no...
In nonsinusoidal systems, a commonly used formula for reactive power is Q equals SIGMA E//nI//n sin PHI //n where n assumes values from 1 to n. It is contended that this widely quoted formula is based on a fallacy. It is an arbitrary mathematical value that does not represent any phy...

Active power, P = (Current)2x Resistance = I2R If the circuit is a purely reactive circuit (resistance=0), active power shall be zero. Reactive power in a purely reactive circuit can be calculated using the following formula: Reactive power, Q = (Current)2x Reactance = I2X ...

(1) corresponds to the relationship ** Formula ** in which u1 and u2 are the phase voltage values of the two-component system, and b 'Y w' are the asymmetric components, - in which the phase voltage values (U2 to U4) multiplied, weighted with the weighting factors (ga to gc), and...
In order to investigate the correlation between active power and reactive power losses, it is assumed that the system operates under normal conditions with voltage levels approximately being maintained around the per unit value of one. Additionally, it is also assumed that the power factor at the ...
