With the excessive needs for energy, the limited powerre sources became the main problem that pushed scientists to work hard on finding solutions for energy saving, and many engineering institutes, labs and research agencies are working hard in the same direction as well.
As known, all electrical equipments that operate with ac current consume two types of power: First: Active Power measured by KW Second: Reactive Power measured by KVAR.
In the eighties of the last century, we knew the Power Factor Correction panels (PFC). The function of the PFC is based on adding capacitor banks relative to the load requirements and adds to the load a reactive current that is supplied by the source, which leads to an increase in the consumed active power.
The client then profits from not paying penalties over the reactive power but pays more for the consumed active power.
Today, our Company is presenting in the market its unique APSS (Active Power Saving System) panels.
* This innovation is the result of 15 years of researches and modifications in the field of
the energy saving.
* APSS when was applied lately added a new economic value as it reduced the amount of
consumed active power and hence reduced the cost of the production and operating
Expenses.

APSS PANEL (Concept of Operation)
The (APSS) unit had ionic treatment with a combination of special materials creates super-conductivity with a negative resistance which acts as a current source in the network that allows us to add the current component in the direction of the active current and another one in the direction of the reactive current, therefore, we reduce the power consumed (KW) from the source without affecting the load.
Negative resistance or negative differential resistance (NDR)
is a property of electrical
circuit elements composed of certain materials in which, over certain voltage ranges,
current is a decreasing function of voltage. This range of voltages is known as a negative
Resistance region.
The basic idea behind negative resistance
Negative resistance phenomenon is a process of injecting an additional excessive power to an existing power source proportionally to some disturbance. A negative resistor acts as a proportional additional power source.
1
Achieves saving from 25 – 50 % over the consumed active power for networks that are
supplied through transformers
2
Achieves saving from 15 – 30 % over the fuel consumption for networks that are
Supplied through generators.
3
Power factor improvement that reaches up to 99% which makes the client benefits
from avoiding paying penalties over the reactive power.
4
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.
5
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.
6
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.
7
APSS unit minimizes, in some applications, the harmonics in the network (3rd, 5th, 7th, 9th, 11th &13th).
8
APSS unit is a tailor-made panel that is designed according to the network conditions, the capacity of each unit can vary between 50 KVA to 2000 KVA.
9
In order to achieve the required saving in the big networks, we can use several APSS panels.
10
APSS unit can handle each phase separately APSS panels are of suitable size and don’t need any additional facilities.
11
APSS panels can be designed to work in any environment.
12
With the use of the APSS panels, client saves location and expenses of new equipments and additional devices he might have spent to increase his network capacity without using APSS panels.
