Power Factor: The electrical energy is almost exclusively generated, transmitted and distributed in the form of alternating current. Therefore, the question of power factor immediately comes into picture. Most of the loads (e.g. induction motors, arc lamps) are inductive in nature … (Read More)

Power Triangle: The analysis of power factor can also be made in terms of power drawn by the a.c. circuit. If each side of the current triangle oab of Fig. 6.1 is multiplied by voltage V, then we get the power … (Read More)

Low Power Factor: The Low Power Factor plays an importance role in ac. circuits since power consumed depends upon this factor. It is clear from above that for fixed power and voltage, the load current is inversely proportional to the power factor. … (Read More)

Power Factor Improvement: The low power factor is mainly due to the fact that most of the power loads are inductive and, therefore, take lagging currents. In order for Power Factor Improvement Methods, some device taking leading power should be connected … (Read More)

Power Factor Correction Circuit: To calculate Power Factor Correction Circuit, Consider an inductive load taking a lagging current I at a power factor cos Φ1. To develop Power Factor Improvement of this circuit, the remedy is to connect such an equipment … (Read More)
