## Power Factor Correction Circuit

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 in parallel with the load which takes a leading reactive component and partly cancels …

## Power Factor Improvement

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 in parallel with the load. One of such devices can be a capacitor. The …

## Low Power Factor

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. Lower the power factor, higher is the load current and vice-versa. A power …

## Power Triangle

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 triangle OAB shown in Fig. 6.2 where The following points may be noted form …

## Power Factor

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 and hence have low lagging power factor. The low power factor is highly undesirable …
