String Efficiency of Insulator: As stated above, the voltage applied across the string of suspension insulators is not uniformly distributed across various units or discs. The disc nearest to the…
Line Support: The supporting structures for overhead line conductors are various types of poles and towers called line support. In general, the line supports should have the following properties :…
Requirements of Satisfactory Electric Supply Connection: The Electric Supply Connection in India is 3-phase a.c. operating at a frequency of 50 Hz. The power station delivers power to consumers through…
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…
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…
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…
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.…
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…
