Objectives Functions
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:
•
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, 5th,
7th, 9th, 11th, 13th).
•
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.

Quality:
Utmost attention to product quality and customer service are constants in DUCATI’s history
and the main factors contributing to its success worldwide
Ducati has always been one of the first companies in its field, in Italy and in Europe, to adopt
the most modern standards and procedures in order to assure the highest level of product
quality and reliability.
The QUALITY SYSTEM of Ducati Energy APSS, capacitor division, as described in the
Quality Manual, was one of the first in Italy to be approved by the BSI in accordance with
ISO 9002 (EN 29002) procedures: Certificate of Registration N.FM 22-04 All this has been
achieved thanks to fully automated and iterated production processes, completely new and
innovative machines, production process control methods based on accurate specifications
and the assigning of responsibility to operator at all levels.
Capacitors systems and relays comply with the requirements set forth in EC Directives
73/23 and 93/68 (“Low Voltage Directive”).
The harmonized European standards of reference are EN60861-1 and EN 60834.2.
Nearly all models are certified international institutes and all the manufactured in full
compliance with the requirements of said standards. The failure rate (for capacitors only) is
300 per 109 components hours (reliability according to DIN 40040).

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 current
signals = coos φ.
Power factor (Pf) = The cosine of
the angle between useful power and
Total power = coos φ = (P/S)

Why improve Power Factor?
The benefits that can be achieved by applying the suitable Power
Factor correction are:
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
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 and
electrical components

Penalty Equation
For 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 Example
For 500000 Kwhr with PF 0.8, we get
For 500000 Kwhr with PF 0.6, we get
Pen=30000 USD
Pen=160000USD
Electricity Bill!
Bonus
For 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.
So, what is happening?
System without Power factor correction
System with Power factor correction
Cosφ = (P/S)
P (Watts)
Cosθ = (P/S1)QC(VARS)
φ θ
QL-QC (VARS)
S1(VA)
QL(VARS)
S (VA)
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.
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
Power factor correction Failed in
1. Decreasing the active power “P”

APSS
Why 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
APSS
Why 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
