In previous studies, a formula to calculate exact THD of phase voltage has been emerged for multilevel inverter with equal DC sources. In this paper, line to line voltage THD formula for 3 and 5-level inverter instead of the past approximate methods is offered. For writing codes and ...

Calculate the line to ground voltage using the formula: V (line to ground) = (KVA x 1000)/(I x 1.73). Continuing with the example: V (line to ground) = (20 x 1000)/(30 x 1.73) = 20000/51.9 = 385.4 volts. Cite This Article MLA Chestnut, Dwight. "How To Calculate 3-Phase L...
For example, line voltage between yellow and blue phase (V_γB) will be given by Vγ - VB which is a vector difference that means the vector addition of VYand - VB. Now we know, VR=VY=VB=V volts as the magnitude of all phase voltages are the same. Therefore, VYB= √3 V, wh...
A 'Line Parameter' refers to the characteristics of a transmission line that can vary with the frequency of the voltage or current waveforms, such as series resistance, inductance, shunt conductance, and capacitance.

if two points ( x 1 , y 1 ) and(x 2 , y 2 )are said to lie on the same side of the line ax + by + c = 0, then the expressions ax 1 + by 1 + c a nd ax 2 + by 2 + c will have the same sign or else these points would lie on the opposite...
to learn goes up in an exponential curve, for it’s certainly true that most of us breathe a hefty sigh of relief when that particular course ends. It’s not impossible to understand waveguides though, and [Old Hack EE] is hereto slice through the formulae with some straightforward ...
