Low power factor in a system arises from unavoidable inductive loads consisting of lighting fixtures, motors, transformers, electromagnets etc. The way to improve power factor and go for better utilization of generation and distribution facilities involves the following— Use of more efficient motors with high power factor. Select optimum sizes of equipment/ motors. They have […]

By installing suitably sized switched capacitors into the power distribution circuit, the Power Factor is improved and the value becomes nearer to 1 thus minimising wasted energy, improving the efficiency of a plant, liberating more kW from the available supply and saving you money!The purchase cost of the installation is usually repaid in less than […]

Increased system capacity and reduced system losses in your electrical system By adding capacitors (KVAr generators) to the system, the power factor is improved and the KW capacity of the system is increased.Uncorrected power factor causes power system losses in your distribution system.By improving your power factor, these losses can be reduced.With the current rise […]

(Note that all these issues result in a change of reactive/ real power) Inductive loading – 90% of the industrial load consists of induction machines (single and three phase). Such machines draw magnetizing current to produce the magnetic field and hence work at low power factor. Variations in power loading – When the system is […]

Higher current is required by the equipment, due to which the economic cost of the equipment is increased. 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. In Points Cross section of conductor increases: As power factor […]

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 […]
