Improve Power Factor & Reduce Electric Energy Costs
Determine Your Power Factor Objectives
1. Improve Power Factor for Individual Motors
Use Fixed Power Factor Capacitors
Power factor capacitors may conveniently be
switched on and off with individual motors. This
assures that the capacitor is energized only during
the times when the motor is energized - when you
need power factor correction. For this type of
application, typically a Fixed Capacitor Bank is used.
This is the simplest and most economical form of
power factor correction. Depending on the manner in
which you connect the capacitor, you may or may
not need to include fuses. See page 6 for more details.
Harmonics will reduce the life of power factor
capacitors. Whenever there are harmonic producing
loads on the power system, the capacitor bank
should include a capacitor protection reactor, that
will “detune” the capacitor bank to a frequency
where no harmonic energy exists. Consult factory
for “detuned” capacitor banks.
2. Improve Power Factor for Entire Facility
Use Automatic Power Factor Capacitors
When the load conditions and power factor in a
facility change frequently, the demand for power
factor improving capacitors also changes frequently.
In order to assure that the proper amount of power
factor capacitor kvars are always connected to the
system (without over-correcting), an Automatic Type
Capacitor System should be used for applications
involving multiple loads.
Harmonics will reduce the life of power factor
capacitors. Whenever there are harmonic producing
loads on the power system, the automatic capacitor
bank should include a capacitor protection reactor,
that will “detune” the capacitor bank to a frequency
where harmonic energy does not exist. Alternatively
it can be supplied as a harmonic filter that
will remove unwanted harmonic frequencies from
the power system. Consult factory for “detuned”
capacitors or harmonic filters.
3. Improve Power Factor for Large Induction Equipment
Use smARTvarTM
Dynamic Power Factor Capacitors
Large inductive loads (large motors, oil drilling rigs,
wind turbines, amusement rides, auto crushers, arc
furnaces, induction furnaces, etc.) typically have
dynamic requirements for reactive energy (kVARs),
these applications require more sophisticated
automatic type capacitor systems with extremely
fast response capabilities. Use smARTvar™ for
applications with large dynamic loads.

Power Factor Solutions from Arteche
Fixed Capacitor Banks (non-automatic)
Arteche Type CFB Power Factor Capacitor Systems offer a fixed
amount of kVARs. They can be supplied with or without fuses or with
circuit breakers. The internal circuit breaker can provide over current
protection as well as satisfy the NEC requirements for a disconnecting
means (when capacitor is not connected between motor and overload
relay). For applications where there may be harmonic producing
loads on the power system, “detuned” capacitor banks are available
to reduce the flow of harmonic currents into the capacitor. Arteche
also offers harmonic filters that will remove harmonics from the power
system.

of kVAR are
switched on-line as needed.
Arteche Type CAB Automatic Power Factor Capacitor Systems
automatically adjust the connected capacitor kVAR to the system
needs based on commands from the internal electronic power factor
controller. The total bank of capacitors is segmented into convenient
increments of kVAR which are switched on-line as needed. Automatic
capacitor systems can be supplied either with or without a main circuit
breaker or switch. For applications that have harmonic producing
loads, automatic capacitor systems can be supplied with an optional
detuning reactor to reduce the flow of harmonic currents in capacitors.
Arteche also offers harmonic filters that will remove harmonics from the
power system.
smARTvarTM Transient-Free Automatic Capacitor Banks
smARTvarTM Type SMV Automatic Capacitor Systems utilize power electronic
technology to achieve extremely fast switching of power factor capacitors. Not
only is this an automatic power factor system, it can switch capacitors on-line in
less than one cycle, to maintain designed power factor when large inductive
loads have very dynamic characteristics. It can respond to the most dynamic of
loads
including arc furnaces, amusement rides, wind turbines, etc. The total
bank of capacitors is segmented into convenient increments of kVAR which are
switched as needed using zero-cross switching thyristors. Capacitor switching is
accomplished rapidly but without transients. These systems can be supplied
either with or without a main circuit breaker or switch. For those applications that
have harmonic producing loads, these capacitor systems are available with an
optional detuning reactor to reduce harmonic currents in the capacitor. Arteche
also offers harmonic filters to remove harmonics from the power system.
Capacitor switching is accomplished
in less than one cycle without

Benefits of Improving Power Factor
Arteche PF Capacitor Systems Offer Rapid ROI
Raise Power Factor
Arteche Power Factor Capacitors will raise the power factor
of motors and other inductive loads. Type CFB capacitors
may be used for individual inductive loads, or to improve
power factor for an entire facility or electrical service.
Use Type CFB Capacitors for commercial, industrial or
municipal applications.
Precise Control of Power Factor
For large facilities or electrical services, consider Arteche
Type CAB Automatic Capacitor Systems. Automatic
capacitor systems are required for multiple loads so that
capacitance can be adjusted based upon varying load
conditions and varying reactive power demand.
Achieve Maximum Reduction of Power Losses
Capacitors should be connected as close (electrically) as
possible to individual inductive loads in order to recover the
highest percentage of branch circuit conductor power
losses. Properly applied capacitors can lower the power
system losses by reducing the circuit current and I2R power
losses.

Inductive loads can demand large amounts of reactive
power and reduce overall facility power factor. The power
factor of individual motors can range from 0.60 to 0.93 and
drops steadily as the load is reduced. Since many motors
are de-rated or operate well below full load conditions,
actual power factors are often lower than stated on the
motor nameplate.
When capacitors are added to power systems supplying
induction motors, the capacitor supplies the reactive power
needed by the motor, thus reducing the reactive power
demanded from the facility power source and improving
power factor upstream of the capacitor connection point.
Arteche capacitors improve the power factor, reduce kVA
demand, save energy and can reduce electric bills. By
reducing the reactive power demand, they can also
release capacity available from existing transformers.
How much is kVA reduced?
Raise PF from 0.80 to 0.95 => reduce kVA by 15.8%
Raise PF from 0.70 to 0.95 => reduce kVA by 26.3%
How Much is current reduced?

ROI for your Capacitor Investment
Capacitors improve the power factor of induction loads.
Additionally, they reduce current and kVA demanded
from the power sources. The payback period will depend
on your electricity rate structure and penalties associated
with low power factor. We can help you determine the
ROI of a capacitor investment. Contact our offices for a
ROI analysis based on your electricity rates and usage.

In electrical equipment, such as transformers or cables,
capacitors can release capacity and thus allow a greater
payload. By furnishing the necessary magnetizing current
for induction motors and transformers, capacitors reduce
the current drawn from the power supply. Less current
means less loading on transformers and feeder circuits. If
a system has an existing overload, the capacitor may
eliminate it. If the system is not overloaded, capacitors
can release capacity and postpone or avoid an
investment in more expensive transformers, switchgear
and cable, otherwise required to serve additional loads.

Excessive voltage sags can make your motors sluggish,
and cause them to overheat. Low voltage also interferes
with lighting, the proper operation of motor controls and
electrical and electronics instruments. Capacitors will
raise your plant voltage level, and can maintain it all
along your feeders, right out to the furthest motors.
How much energy will capacitors save?
By supplying kilovars at the point where they are needed,
capacitors will relieve the system of delivering reactive
current. Since electrical current in the lines is reduced,
the circuit I2R losses also decrease. Therefore, fewer
kWh need to be purchased from the utility. ROI will vary
depending on factors such as utility rate structure, load
conditions, old PF and new PF.

Understand Power Factor & Determine Capacitor Requirements
Power Factor Tutorial
Electrical systems perform with some degree of efficiency
ranging from poor to excellent. One measure of efficiency
compares the work produced (kW) with the apparent
power (kVA) that is demanded from the power source,
for the purpose of performing that work. The kW/kVA is
a measure of electrical efficiency and is known as
Power Factor (PF).
Motors need kVARs—Capacitors supply kVARs
Motors and other inductive equipment in a plant require
two kinds of electric power. One type is working power,
measured by the kilowatt (kW). This is what powers the
equipment and performs useful work. Secondly, inductive
equipment needs magnetizing power to produce the flux
necessary for the operation of inductive devices. The unit
of measure of magnetizing or reactive power is the kilovar
(kVAR). The working power (kW) and reactive power
(kVAR) together make up the apparent power which is
measured in kilovolt-amperes (kVA).
Capacitors most effective at the Load
Most AC power systems require both kW (kilowatts) and
kVAR (kilovars). Capacitors installed near the inductive
loads in a facility are the most effective way of supplying
these kilovars, and can provide the greatest reduction of
branch circuit power losses. If not supplied by local
capacitors, then these kilovars will need to be provided by
the electric utility. Arteche low voltage capacitors are a low
cost, high reliability and maintenance free means of
providing the needed kilovars.
Capacitors Relieve Power System of Reactive Current
If magnetizing current for inductive loads is provided by
capacitors, then those kilovars do not have to be sent all
the way from the utility to the inductive loads. This relieves
both your electrical system and your utility of the cost of
carrying these extra kilovars. The utility typically charges
for this reactive power through either a direct or indirect
power factor penalty charge. Capacitors can reduce your
electricity demand and can reduce your utility bill, gain
system capacity, improve voltage and reduce power
losses.
Induction motors, transformers and many other electrical
loads require working power (kW) as well as magnetizing
power (kVAR).
Considering kW and kVAR as the
sides of a right triangle, we can determine the
apparent power (kVA) based on the right triangle rule.

Thus eliminating these kVA

By supplying this
kilovars with capcitors
By supplying kVAR directly at the load, the motor receives
the reactive power that it needs and the capacitor relieves
the utility of the burden of carrying the extra kVAR.
This reduces both current and kVA in the branch circuit
conductors and in the upstream power system. This makes
the utility transmission and distribution systems more
efficient, reducing cost for the utility and their customers.
The ratio of actual power and apparent power is usually
expressed in percentage and is called power factor.

Determining your capacitor kVAR requirement
Find the kVARs you need in 3 easy steps.
Select Proper Capacitor (kVAR) in 3 easy steps:
1) Find your Desired Power Factor at top of chart.
2) Slide down to the row corresponding to your
Original Power Factor
3) Multiply your KW by this factor to determine the
required capacitor kVARs.
8
Example:
If Load is 720kW, 0.75 PF and Desired PF = 0.95 (95%)
1) Find 95% in top row.
2) Slide down that column to the row beginning with 75%.
Find factor = 0.553.
3) Multiply 720kW by 0.553.
Capacitor needed is 398.16kVAR (use 400kVAR).
