Phasor analysis, power factor, and the calculation of three-phase
҉ Fasor sinusoid wave
In the field of electronics, bearan-scale current and voltage can be calculated by measuring because these quantities do exist and manifest in a series. But in the calculations are often settled by way of abstraction because in addition to simplify calculations, the concept of abstraction phasor important in electronics education. Phasor state transformation of a function of time into a complex field that contains information about the amplitude and phase angle.
Analysis of the spin vector at specified intervals called phasor analysis which, if associated with sine wave form will allow the depiction of phasor sinusoids are very important in an electronic problem.
1. There are many phenomena in nature which can be described as a sinusoidal wave.
2. Because of easy pembangktannya, then the current and voltage in the power generation shaped sinus.
3. Appropriate description of Fourier series, all other periodic waves, with certain conditions can be decomposed into the sum of sine waves with varying frequency.
In a linear circuit consisting of resistance (R), inductor (L) and capacitor (C), if a current or voltage is a sinusoid, then semuja currents and other teganagan dengaan sinusoids also shaped the same frequency.
Through the Kirchoff law there are 3 ways to addition and subtraction sinusoids forms:
1. Graphical way, by describing the wave after wave and added all the time. It's time consuming and not precise.
2. How to trigonometry, using the arguments of trigonometry to add and subtract two sinusoids. This method is difficult and time consuming.
3. How da complex algebraic phasor analysis as described earlier. Aiani is the easiest way.
҉ power Fasor and power complex
From the preceding discussion can be seen that the average power is not a function of current and voltage rms, but there are distinctive elements of the current and voltage phase angle.
Voltage multiplied by current is called pseudo-power. The average power divided by apparent power is called power factor.
If a given load voltage, the impedance of the load, the impedance of the load will determine the amount of current flowing and the phase angle on the load. Power factor is an indication that states the nature of a burden.
҉ Calculation of three-phase
Almost all the electricity used by industry, generated, transmitted, and distributed in 3 phase system. These systems have the same magnitude for voltage or current but have different angles of 120 ˚ antarfasanya.
If the source supplies a balanced load, the current flowing in each of the Conductor will have the same magnitude and phase angle different from 120 ˚ to each other. This current flow is called balanced.
