Effects of Harmonics
Effects of Harmonics: The relationship between line and phase quantities for wye and delta connections as derived earlier are strictly valid only if the source voltage is purely sinusoidal. Such…

Maximum Power Transfer Theorem: Here, the maximum power transfer theorem has been discussed for resistive loads. The maximum power transfer theorem states that the maximum power is delivered from a…
Phasor Diagram Sine Wave: A phasor diagram can be used to represent a sine wave in terms of its magnitude and angular position. Examples of Phasor Diagram Sine Wave are…
Measuring the Sine Wave: As the magnitude of the waveform is not constant, the Measuring the Sine Wave can be in different ways. These are instantaneous, peak, peak to peak,…
Sine Wave Equation: A Sine Wave Equation is graphically represented as shown in Fig. 4.10(a). The amplitude of a sine wave is represented on vertical axis. The angular measurement (in…
The Sine Wave: Many a time, alternating voltages and currents are represented by a sinusoidal wave, or simply a sinusoid. It is a very common type of alternating, current (ac)…
Indirect Testing of Circuit Breaker: With the increase in the breaking capacity of the HV circuit breakers, it has become uneconomical and unpracticable to increase the short-circuit capacity of testing…
Direct Testing of Circuit Breaker: The Direct Testing of Circuit Breaker in a plant enables us to test under conditions largely representing those in actual network as well as tests…
