Simultaneous Power Factor Correction and Harmonic Filtering.
The power factor correction is a technique of increasing the power factor of a power supply. Switching power supplies without power factor correction draw current in short, high-magnitude pulses. Displacement PF is defined as the cosine of the angle between fundamental voltage and fundamental current of the load. The presence of Harmonics increases the RMS current and voltage relative to their respective fundamental values. This increases the KVA of the Load. The Power Factor correction capacitor taking into account the effect of the Harmonics is called the true power factor..
True PF ≤ Displacement of the factor by which Displacement PF is related to the True PF is called the Distortion PF
The power factor of your installations can be improved by the placement of power factor capacitors where they work as reactive generators of power. This is required when you notice that the apparent current is superior to the working current that you are getting.
Only Power Factor Correction Capacitors can improve Displacement in Power Factor
The application of shunt capacitors to industrial power systems has several benefits. Among these are:
Benefit 1 — Reduce Power Bills
Benefit 2 — Gains in System Capacity
Benefit 3 — Improve Voltage Conditions
Benefit 4 — Reduce Line Losses
Listed below are various installation options. Care must be taken in sizing and placing power factor correction capacitors. Leading power factor, greater than 100%, must be avoided. The capacitors should only be online when the load requires kVAR and disconnected when the load is reduced.

What is KVAH Billing?
In kVAh (kilo volt ampere hour) based billing system, the fixed charges or demand charges are levied on apparent power (kVA) and energy charges are levied on apparent energy (kVAh). Because of kVAh billing system, Real and Reactive energies need not be charged separately.
Penalty on electricity bill
The paradigm shift in the tariff structure is going to have a huge impact on the way the power quality is maintained in any organisation having huge consumption of power in India.
Lot of states like Himachal Pradesh, Delhi, Uttar Pradesh, Jammu & Kashmir, Andhra Pradesh, Chhattisgarh, Bihar, Haryana, Punjab etc. have already introduced kVAh based tariff for various categories. This has made consumers focus of Power Quality or their organisations much more seriously.
The new structure is based on monitoring KVAH (the apparent energy) lead in totality instead of charging active and reactive energy separately. This billing is associated with an in-built PF incentive /penalty mechanism.
The implantation of KVAH billing will not only assure near unity Power Factor but also ensure a check on harmonic generation and pollution of the electrical grid, as harmonics have a direct effect on KVA which in- turn will reflect in the bill and warrant a penalty. Thus, encouraging consumers to retort to adopting energy efficiency programs.

Refurbishment Service
Harmonic create higher heating losses, causing harmonic voltage and current distortion so to solve this problem, we need Harmonic Filters.
Let’s understand what is harmonic before going ahead. The Non-linear load that comes on the power supply unit which leads to an uneven amount of power supply from the power supply units, which affects the health and life span of your Machines and Electronic equipment.
To Get rid of this problem there are filters which are known as Harmonic filters. These harmonic filters reduce the distortions in the power supplies so that there is no power distortion.
Generally, there are 3 types of Harmonic filters
Active harmonic filters
Active filters are those devices used to reduce the harmonics and improve the power flow.
Passive harmonic filters
Passive filters are resistors that resist the increasing flow of Non- linear power load
Hybrid Harmonic Filters
Combination of Active and Passive harmonic filters are called Hybrid Harmonic Filters. One of the best instruments to reduce harmonics is to have Hybrid Harmonic filters. Hybrid filters are Cheaper and more reliable as compared to Active and Passive harmonic filters.
Power Factor Correction (PFC) equipment is a technology which if installed enables the customer to decrease their electricity bill by maintaining the level of reactive power consumption reduced.
If a sites Power Factor falls below a predetermined figure then the electricity company adds reactive power charges to your bill. In general, the strain on the electrical infrastructure is controlled if the Power Factor is good.
So the main role of power factor correction is to correct the power factor to avoid excessive power bills.
Before understanding the types of filters and how they control harmonics, it is important to understand, what are harmonics?
Harmonics occur when there is an overload on the source from which the power comes. Excessive load on power supply creates distortion in which are known as harmonics.
There are 3 types of Harmonic Filters that reduce harmonics
Active Harmonic filters
Passive harmonic filters
Hybrid harmonic filters
And here's how they reduce the harmonics in the power supply system.
Passive Harmonic Filters
The Passive Harmonic filters are of 3 types series tuned, double bandpass and damped filter.
Out of these three filters Some filters are used to reduce single tuned harmonic filters whereas some filters are used to reduce two frequencies of harmonics.
A passive filter consists of a series circuit of reactors and capacitors. Harmonic currents generated by, for example, a frequency converter are rechanneled by passive harmonic filters which are designed to have low impedance at a given frequency.
Active Harmonic Filters
Active filters are systems which are installed in the manufacturing units, where there is high harmonics in power supply. Active filters controls the nonlinear loads that arise due to pressure on power supply.
Hybrid Harmonic Filters
Hybrid Harmonic Filters are a unique combination of Active and Passive technologies being offered in a single system, thereby maximizing the benefits of both technologies at the same time eliminating the shortfalls.
APFC Panel is Automatic power factor correction panels. These APFC panels are Installed in the place where there is a large electric load and high amount of Power supply.
Today as the Cost of Electricity has increased it is important to make optimum use of electricity.
This is where APFC Panel helps us; These Panels are required to improve the power factor in the electrical system.
Harmonics increase the measure of power required by the system because of a decrease in power quality, adding to a lower power factor and higher energy costs because of the diminished effectiveness of the system. Harmonic filters act to channel through the electrical sounds in a system. This can diminish the overheating of hardware, decrease irritation stumbling of circuit breakers and intertwines, and improve power quality adding to decreased energy costs.
The inside of a harmonic filter is comprised of a variety of resistors, inductors, and capacitors that are equipped for redirecting undesirable consonant flows, sending them to ground. A portion of these channels is intended to avoid sounds of a particular recurrence or frequencies.
Harmonic Filters are more proficient for power factor relief due predominantly to its adaptability.
As power factor issues are generally brought about by harmonic produced by non-direct gadgets. The best way to deal with alleviating the issue is by counteracting it by delivering an equivalent yet inverse impact to enable its cancellation.
The harmonic filter being effortlessly tuned-capable can be changed in accordance with produce a similarly balancing and out of phase harmonic. That in actuality will drop and stifle any commotions present in the lines, hence improving the power factor.
So in the event that one is utilizing Power Factor correction and the heap has a high symphonious substance than one may consider utilizing both Power Factor and Harmonic Filters], in any case, the harmonic may cause the Power Factor revision capacitors to overheat and in this way, one would need to oversize the Power Factor correction capacitors. For this situation, they may supplement one another.
It is consistently hard to choose tuned Power Factor capacitor frameworks when the harmonic substance is high. The tuning will, in general, be troublesome because of the plentifulness of the harmonic current that moves through the capacitor circuit. The arrangement is to make the Power Factor capacitor VARs bigger so as not to over-burden the capacitors. This may protect the capacitors however can cause driving Power Factor now and again. The active harmonic filter won’t cause driving Power Factor whenever and couldn’t care less if harmonic are available while performing PF correction.
Passive harmonic filters:-
Uses a mix of reactors and capacitors to shift through consonant frequencies. These filters help in reducing current distortion that could lead to overheating of equipment and cause circuit overload.
Active Harmonic Filters:-
Provides symphonious pay by being introduced on the line side of the culpable burden (for instance, VSD). They present current waveforms which offset undesired harmonic parts. Also, these filters are used in a commercial installation.
Hybrid PQ filters:-
Hybrid harmonic filters are used to combine passive and active filters for industrial installation.
Every one of these options has its place in the market. It is significant that a client recognizes the measure of harmonic distortion that should be killed before a filter is picked. Active filters, for instance, are ideal when there is more than one sort of burden present, for example, UPS, VFD, and DC drive.
Passive filters can be very effective in reducing harmonics in your power supply network. The Passive Harmonic filters are a series tuned filter double bandpass filter and damped filter.
This series tuned filter is applied to compensate a single tuned harmonic frequency and double bandpass filter is used to compensate two harmonic frequencies. These filters will reduce the lower-order harmonics.
The cost of the Passive harmonic filters is very low as compared to that of Active Harmonic filters and it is easy to reduce the harmonics to a particular level.
APFC panels are used to Supervise and Manage the voltage and reactive power of the control system.
We manufacture and provide a qualitative range of APFC panels that are extensively used in many industries. Those automatic power factor control panels (APFC) are created and developed using advanced techniques and are capable of saving maximum power and energy.
These APFC panels are very efficient and accurately control the reactive power in control systems for storing energy and can alter the system voltage as well as flow.
These APFC panels are also produced with capacitors along with a series of reactors to reduce the harmonic current.
Passive filters can be very effective in reducing harmonics in your power supply network. The Passive Harmonic filters are a series tuned filter double bandpass filter and damped filter.
This series tuned filter is applied to compensate a single tuned harmonic frequency and double bandpass filter is used to compensate two harmonic frequencies. These filters will reduce the lower-order harmonics.

Power factor correction allows you to calculate apparent power, real power, reactive power, and your side angle. Consider the comparison of a right triangle. So to calculate the angle you want to know your Cosine, Sine, and Tangent laws. You also wish to know The Pythagorean Theorem ( c² = a² + b² ) for determining the magnitudes of the sides of the triangle.
You will also be required to know what units each kind of power is in. Possible power is measured in Volt-Amps. Real power is measured in Watts and your Reactive power is marked in the units called Volt-Amp-Reactive (VAR’s). There are many equations to calculate. You now have the basis of the Power factor you are trying to calculate.
Generally, the Power factor of all the machines is Lagging in nature. We can see this in our home digital energy measure as 0.8 or 0.9 pf. The lagging power factor is due to the inductance present in all the devices such as windings in the fan’s armature, compressors in AC and Fridge, etc. All these appliances consume Lagging VAR for their operation. If the appliances consume more VAR then the response of the device is poor and failures occur.
Capacitors ideally only draw Reactive Power. They don't regularly receive electrical energy as radiators and motors. Rather, they charge and then release. They skip the energy back to the source.
Capacitors supply the Lagging VAR required by the appliances. So, the Reactive power drawn from the Mains amount gets reduced. And the power factor of the way gets developed.
In a capacitor, Current leads Voltage by 90 degrees. Therefore Current power drawn by the capacitor is zero. Capacitors both supply Lagging VARs or Consume Leading Vars.
It all has to do with overtones. In a nutshell, the sound is a concentration wave. ... Every tone is at a set frequency, so the high mark in the wave occurs every so often. An overtone, which is what a harmonic filter is, occurs when you have two sound loops whose high points overlap at certain intervals.
APFC Panel has a microcontroller-based programmable controller that switches the capacitor banks of proper capacity automatically in various stages by directly showing the reactive load (RKVA) which runs in the system of VAR sensing tends to control the PF to 0.99 Lag. The capacitor banks may be elected in several stages as 4/6/8 according to the load model.
APFC Panels become real handy in the success of this purpose Use of these command panels becomes necessary in those industries where electrical connections are meant to satisfy a large electrical load.
A dip in Power Factor can attract operational losses and a fine from the electricity board, responsible for power supply
Harmonics generated by equipment such as VSDs can cause changes in the electrical grid that will not only affect things in the related installation but besides other consumers fed from the equal transformer. Unfavorable effects of harmonics including extra heating and power losses in transformers, motors, and wires; accidental circuit breaker tripping; and checking with and damage to capacitor banks.
As a result, power experts usually require harmonics to be kept to a minimum – typically <5%. To do this where nonlinear parts are involved, harmonic filtering is usually required.
Filtering plans are more important to various electronics designs because they kill unwanted frequencies. They are modern forms because both do not need a power supply and depend on passive elements rather than existing components. This column gives knowledge about the advantages and disadvantages of passive filters to properly explain this topic.
Advantages of passive filters:
It is safe
They can manage large voltage flows and power
There is no limitation on the frequency range
They do not need the additional dc power supply for their operation
Easy to form
Cheaper as analyzed to active filter
No amplifying elements
Disadvantages of passive filters:
Fixed reactive power compensation
Large in size
There is no separation between input and output
The circuit converts bulky if inductors are used
There is forever some loss of sign it can be in the passband
This course can not provide each gain
Source filling can take place
There is no clear demarcation within passband and stopband but really, it gets tangled up
The simplest way to increase power factor is to add PF correction capacitors to the electrical method. PF correction capacitors work as reactive current dynamos. They better offset the non-working energy used by inductive loads, thereby increasing the power factor.
