APFC stands for ‘automatic power factor correction’. An APFC panel consists of multiple capacitors of different ratings whose switching can be controlled as per requirement. An APFC is effective as a single-point installation which can be used to control the power factor for a large number of loads, instead of installing capacitors at the individual locations of each load. An APFC panel consists of multiple […]
A low power factor is a burden on transmission company. Earlier, they used to adjust pwoer factor losses in transmission losses, however, since the inception of kVAh billing, the companies pay for the low power factor through their pockets. In a thermal power plant coal is burnt to produce electricity. Now as we all know, […]
In all industrial electrical distribution systems, the major loads are resistive and inductive. Resistive loads are incandescent lighting and resistance heating.At low power factor, the current is high which gives rise to high copper losses in the system and therefore the efficiency of the system is reduced. Typical inductive loads are AC motors, induction furnaces, transformers and ballast type lighting. Inductive loads require two […]
Before answering this question, we must understand what power factor and the harmonic spectrum mean. The powerfactor is the ratio of real power to the magnitude of apparent power consumed by a load.pf=P/SWhere the apparent power is the vector sum of real and reactive powers consumed by the load. S=VI* Now we know that the harmonics are integral multiples of the fundamental frequency,Since reactive power is directly proportional to the frequency ( in case of lagging loads)Higher the frequency implies higher the reactive power consumption. Hence the ratio of reactive power to the real power (or) ratio of reactive power to apparent power is quite high for harmonics , In other words reactive power would dominate the real power (for harmonics). This CLEARLY […]
Electricity is arguably the most valuable resource we have in our modern society. Without electricity, most of the things we do and rely on on a daily basis wouldn’t be there.
