An inverter has a periodic output voltage with the output waveform as shown in figure

When the conduction angle $$\alpha = {120^0},$$ the $$rms$$ fundamental component of the output voltage is

An inverter has a periodic output voltage with the output waveform as shown in figure

With reference to the output waveform given in figure, the output of the converter will be free form $${5^{th}}$$ harmonic when

A $$3$$-phase, $$11$$-$$kV$$ generator feeds power to a constant power unity power factor load of $$100$$ $$MW$$ through a $$3$$-phase transmission line. The line-to-line voltage at the terminals of the machine is maintained constant at $$11$$ $$kV$$. The per unit positive sequence impedance of the line based on $$100$$ $$MVA$$ and $$11$$ $$kV$$ is $$j$$ $$0.2$$. The line to line voltage at the load terminals is measured to be less than $$11$$ $$kV$$. The total reactive power to be injected at the terminals of the load to increase the line-to-line voltage at the load terminals to $$11$$ $$kV$$ is

Bundled conductors are mainly used in high voltage overhead transmission lines to
