• 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
