• Energy saving panels to save in electric consumption (kwhr) (active power) by an amount
ranging not less than 20% reflected on monthly electric bills.
• Special motors (chocks) for harmonic reduction.
• Special ant resonance harmonic fillers with electric regulators for the adoption of their
characteristics to harmonics creation sources.
• Raise the power factor to 0.99, as a result of optimisation of power factors with regard
to the harmonic and the restive contents.
• Reduction of current-voltage harmonics.
• APSS unit minimizes, is some applications, the harmonics in the network (3red, 5 th,
7th, 9th, 11th, 13th).
A scientific project for power factor quality improvement and saving, by the reduction of current voltage harmonics, the improvement of electric motors efficiency and the reduction of active power consumption ( kwhr ) and currents at the building.
The project includes the scientific study, design, and installation of:
Objectives Functions
• APSS panels are of suitable size and don’t need any additional facilities.
• APSS panels can be designed to work in any environment.
• Improvement of motor’s efficiency.
• Reduction of supply currents and considerable saving.
• Reduction of the requested apparent power.
• No negative impact on the network, according to authorized certificates.
• The network resistance is reduced due to the energy exchange between the APSS
unit and the different loads; therefore, the consumed current from the source is
reduced.
• APSS unit works on minimizing the network losses and acts as
A VOLTAGE STABILIZER to a certain extent which leads to reduce the consumed
current from the source.
• APSS unit can handle each phase separately which leads to balance the load of the
network, therefore it minimizes the current flow through the neutral cable of the
network.
The Advantages of the APSS Panel
Egyptian product. Achieves saving not less than 20% over the consumed active power
for networks that are supplied through transformer. Achieves saving not less than 30% over the fuel consumption for
networks that are supplied through generators. Power factor improvement that reaches up to 0.99 which makes the
client benefits from avoiding paying penalties over the reactive power.
The network resistance is reduced due to the energy exchange between APSS unit & the different loads; therefore, the consumed current from the source is reduced.
APSS unit works on minimizing the network losses and acts as a voltage stabilizer to a certain extent which lids to reduce the consumed current from the source.
APSS unit can handle each phase separately which leads to balance the load of the network, therefore it minimizes the current flow through the neutral able of the network.
• APSS unit minimizes, in some applications, the harmonics in the network (3rd, 5th, 7th,
9thy, 11th, & 13th)
• With the use of APSS panels, client saves location and expenses of new equipments and additional devices he might spent to increase his network capacity without using APSS panels.
• AME provides monthly check-up and preventive maintenance by a highly qualified technical teams for projects inside Egypt and Trains qualified technical staff on site for projects abroad (optional for Egypt).
• APSS panels are of suitable size and don’t need any additional facilities.
• APSS panels can be designed to work in any environment.
APSS panels can be easily installed and dismounted only by Bassant-Tech. Team, or by any team certified from AME
S.N. Networks’ Common Problems APSS Solution
1The amount of the monthly electricity
invoices
APSS salves 20 - 30% over the consumed
active power without affecting the load, therefore
saves the same percentage over the electrical
invoices amounts
2The insufficient efficiency of the
Power factor Correction Panels
APSS achieves the best power factor relative to
the load
3The increase of the power
consumption in the peak intervals
APSS minimizes the increase of the power
consumption in the peak intervals by achieving
more saving proportional to the load demands as
it brings more phases into operation
automatically
4The increase of the different types of
losses (thermal…)
APSS decreases the consumed current from the
source (without decreasing the load current)
which leads to the losses decrease in the
network.
5 Voltage dropAPSS acts to a certain extent as a
voltage stabilizer
6The presence of Harmonics which adds
losses and causes troubles in the network
APSS treats in most of the applications
the harmonics without adding more
equip- mints to the network
7
The unbalances of the loads, that leads to
increase of the current that goes through
the neutral cable
APSS balances the net-workloads,
therefore minimizes the current going
through the neutral cable.
8The repetition of the troubles due to the
different problems of the network.
APSS improves the network efficiency
and leads to have a clean, clear and
stable network.
9 The obligation of buying additional
APSS allows the client to use the saved
energy for load increase within the saved
range without adding more devices or
buying more power from the electricity

Electrical Power Types
Almost all bulk electric power is generated, transported and consumed
in an alternating current (AC) network.
Elements of AC systems produce and consume two kinds of Power:
Real Power “P” (measured in watts)
It accomplishes useful work (e.g., running motors)
Reactive Power (measured in vary).
supports the voltages that must be controlled for system reliability
Power Factor
Power factor (Pf) = The cosine of the angle between Voltage and currentsignals = coos φ.

Environmental benefit. Reduction of power consumption due to improved energy efficiency. Reduced power consumption means less greenhouse gas emissions and fossil fuel depletion by power stations
Why improve Power Factor?
The benefits that can be achieved by applying the suitable Power
Factor correction are:
Reduction of Electricity Bills
Extra kVA available from the existing supply
Reduction of I2R losses in transformers and distribution equipment
Reduction of voltage drop in long cables
Extended equipment life – Reduced electrical burden on cables

Electricity Bill!
Penalty EquationFor a PF between 0.72----0.92, the penalty per year in L.E (Pen.) is calculated as follows:
Pen.= Kwhr per year × (0.92-average PF) × 0.5 USD
For a PF below 0.72, the penalty per year in L.E (Pen.) is calculated as follows:
Pen.= Kwhr per year × (0.92-average PF) × 1.0 USD
Numerical ExampleFor 500000 Kwhr with PF 0.8, we get Pen=30000 USDFor 500000 Kwhr with PF 0.6, we get Pen=160000USD
Electricity Bill!
BonusFor a PF above 0.92, the Bonus per year in L.E is calculated as follows:
Bonus = Kwhr per year × (PF-0.92) × 0.5 USD
Numerical Example
For 500000 Kwhr with PF 0.96, we get
Bonus=10000 USD
How to improve Power Factor?
Power factor correction is achieved by the addition of capacitors in
parallel with the connected motor or lighting circuits and can be applied
at the equipment, distribution board or at the origin of the installation.
Capacitors contained in most power factor correction equipment draw current
that leads the voltage, thus producing a leading power factor. If capacitors
are
connected to a circuit that operates at a nominally lagging power factor, the
extent that the circuit lags is reduced proportionately.
So, what is happening?

Now; we can say that
Power factor correction succeeded in the following:
1. Decreasing the shift between P and S, thus increasing PF
2. Decreasing the reactive power Q, thus reducing or eliminating
the penalty from the electricity bill

APSSWhy APSS ?1- When used with loads supplied from an electrical network, it can
save up to 40% of the Active Power
2- When used with loads supplied from Diesel generators, it can
effectively save the amount of used fuel
3- When used with inductive loads, it can safely improve the PF, thus
eliminating any penalties and gain Bonus
4- It has much less dimensions compared with PFC units
5- It operates automatically to suit different load variations
6- It has much simple design, and needs much less maintenance
APSSWhy APSS ?7- Our clients no longer need to increase their input power for
further loadings, they can increase their loads up to 40 % without
any changes in the feeders.
8- PSU is being Guaranteed by B-Tech for five complete years, through
which professional maintenance and supervision is given
9- Has much competitive Price compared to the percentage saving,
where the client mostly regain his investment in about one year
10- The usage of PSU simply reduces the end production marginal cost
