IntroductionWith the world growth and development, the problem of limited power became apparent. Limited energy became one of the main problems that scientists, engineers, and institutions worldwide worked to overcome. As it is known, electrical consumption operates mainly on Alternating Current (AC). All equipment that operate on AC currents consume two types of power:a. Active Power –measured by KWb. Reactive Power –measured by Kvar

In the final decades on the 20th century, we were introduced to Power Factor Correction technologies (PFC) that function by adding capacitor banks relative to the load requirements which add to the load a reactive current that is supplied by the source, leading to an increase in the consumed active power. That benefited the user by avoiding the payment of penalties on reactive power but on the other hand increased the cost due to increased consumption of active power.


Today, Basant Technologies presents the latest breakthrough in power saving systems, the APSS (Active Power Saving System).

Introduction

APSS is the result of 15 years research and development in the field of energy saving.

When applied to an electrical network, APSS reduces the amount of consumed active power and hence the operational cost of fuel and equipment.

APSS solves common network problems as illustrated in the following table:


Common Electrical Network Problems Contracted electricity bills, or the cost of power production (Fuel, Equipment usage etc.) , where applicable

The inefficiency of the Power Factor Correction Panels

The presences of Harmonics which adds losses and causes problems in the network

The unbalance of loads that leads to the increase of the current that goes through the neutral cable

Voltage drops and instabilities

APSS provides a saving between 20% and 40% of the consumed active power without affecting the load, rendering a saving of the same percentage on energy subscription/ production costs.

APSS achieves the best power factor relative to the load without additional modifications.

APSS treats in most applications the harmonics without adding additional components to the network.

APSS balances the network loads and provides efficient load‐sharing, therefore minimizing the current going through the neutral cable

APSS acts to a good extent as a voltage stabilizer which minimizes the occurrence of irregular voltage drops or increases.


The (APSS) unit uses components that go through ionic treatment with a combination of special materials creating super‐conductivity with a negative resistance, which act as a current source in the network , allowing 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.

WHAT IS APSS?

APSS is an internationally renowned state of art in energy saving and power conditioning system, with proven performance and satisfied customers in many countries worldwide. APSS is the only integrated modular system in the world specifically custom engineered to effectively and economically optimize power quality with guaranteed electric saving of up to 40%, and nominal payback of less than two years without any disruption to equipment or machinery. APSS is versatile and is available in different sizes based on your facility requirements. APSS multistage system is triple protected with each stage independently monitored, protected and activated, resulting in simultaneous addressing of multiples and functions. This eliminates the need to purchase a number of different devices to correct each anomaly.

APSS is a designed system which works in conjunction with sophisticated automation equipment.


This application is recommended when the loads of the network are not stable or are allocated away from each other. Basant Tech carries a site inspection and loads studies then recommends the best solution to the client.

Testimonials "Installing APSS System"

The cable losses are proportional to the square of the current value (this squared value is added to the counters readings of the KW. hr), i.e.: reducing the consumed current by 20% reduces significantly the cable losses. General compensation could be applied for a group of loads or a complete network by installing the system on the main feeders' bus bars as long as the network is stable.


We are all aware that energy saving through power factor Improvement mainly depends on Installing capacitors that adds current on load Increase and hence decreasing current from source. There are three possibilities for current added through capacitors:

1. Capacitors that are not equipped with any Internal resistance; In this case It adds to the reactive current without any Increase In active current. (This kind of device Is not available In the market)

2. Capacitors that are equipped with internal resistance and mainly function to decrease reactive current from source which Increase consumption, as shown In figure (b). According to IEC power factor correction panel should never be more 2 W/kVAr.

3. Capacitors that are equipped with a negative resistance (Introduced APSS system). It functions to decrease both active and reactive currents and hence decreasing consumption and power factor, as shown in figure (c).

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:

supports the voltages that must be controlled for system reliability

Real Power “P” (measured in watts)

It accomplishes useful work (e.g., running motors)

Reactive Power (measured in var).

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 and electrical components

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.

APSS relies on a new Technology that uses special capacitors, with unique specifications .

APSS Capacitors are chemically treated, such that they gain negative resistance

PSU


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.

1. Decreasing the shift between P and S, thus increasing PF

2. Decreasing the reactive power Q, thus reducing or eliminating
