Worldwide countries like Bangladesh are also emphasize on the production of the electricity and at the same time they are giving emphasize on proper and precise uses of the produced electricity. That is why electricity saving issues are always more discussed among the concerned persons. Because costly produced electricity should not be wasted and should be used properly. To aware the mass people to proper and precise uses of electricity and to avoid electricity waste we need to work together in the public and private sector. If we save 1KW/Hour electricity that means it is equal to production of 1KW/Hour.

Besides the awareness of the electricity proper uses of electricity people are now starting to use energy saving technology and products to reduce the electricity consumption. Bangladesh also starting to use energy saving technology and products. Some projects already been done with this technology in the public sector and huge projects also been done in the private sector.

There are so many energy saving technology and products developed worldwide. For Bangladesh we can use very popular and cost effective daylight harvesting technology. This technology will ensure the constant lux level (required light level) inside the room while outside of the room is cloudy or sunshine. If we get the required level of light from outside, no light will turn on inside the room and if we will not get required or insufficient light from outside due to cloudy or rainy weather in that case all the lights will turn on automatically inside the room and maintain required lux level automatically. This is called daylight harvesting by dimming technology. We can use motion sensor in the stair case, toilet areas, lift lobby and store rooms. This motion sensor will turn on the lights automatically when you enter in the room or covered areas and switched off automatically when you left the room or covered areas within few minutes. We can also control air conditioners by this sensors by adding relays. This is how we can save energy at the same time electricity bills.

We have recently introduced a great innovative product called iVolt – that saves 30% electricity bills and at the same time it will work as Automatic Voltage Regulator which will ensure balanced output.

For sustainable development, Bangladesh needs to have the green and clean energy to ensure the ecofriendly environment for our next generation. For green energy we need to emphasize on renewable energy and for clean energy we need to emphasize on some correction products to ensure clean and uninterruptible energy. Power Generation Technology (PGT) – a leading importer, manufacturer and supplier of Automatic Voltage Regulator in Bangladesh for voltage correction to ensure required level of voltage for domestic and industrial uses.

Online term refers to the condition when converter is in operation when power in the line is present. Offline mode refers to a condition when converter operation start after the main line is off or not available. Therefore, online UPS is a stage which is introduced between the load and mains.

What is online and offline UPS?

Offline UPS’s are the Simplest and Least Expensive. When Mains is Present, it is Routed Straight through the UPS Bypassing the Inverter to the Output. Online UPS’s take the Incoming AC mains Supply and Convert it to DC which feeds the Battery and the Load via the Inverter.

What is the difference between online ups and offline UPS?

Off line UPS passes the AC Mains Supply directly to the output load if the AC Mains Supply is present.Only in the case of power failure, it switches to inverter within few miliseconds to give power to load until mains supply returns.

On the other hand On Line UPS always charges battery from incoming AC mains supply and supplies power to load via the inverter.Even if the mains supply fails, there is no interruption to the output load at all. Generally On Line UPS unlike off line UPS are expensive and inefficient as Inverter is continuously in operation. However it provides greater quality of power as compared to offline UPS.

How does battery backup work?

How does an Uninterruptible Power Supply (UPS) work? An uninterruptible power supply (UPS), also known as a battery backup, provides backup power when your regular power source fails or voltage drops to an unacceptable level. A UPS allows for the safe, orderly shutdown of a computer and connected equipment.

Distribution Transformer is an electrical isolation transformer which convert high-voltage electricity to lower voltage levels acceptable for use in homes and business. A distribution transformer’s function is straightforward: to step down the voltage and provide isolation between primary and secondary. Electrical energy is passed through distribution transformers to reduce high-distribution voltage levels down to end-use levels. Nearly all energy passes through at least one distribution transformer before being consumed by an end-use appliance, motor, or other piece of equipment. Distribution Transformers are found in all sectors of the economy: residential, commercial, and industrial.
Distribution transformers are generally categorized in several ways:

• type of insulation: liquid-immersed or dry-type
• number of phases: single-phase or three-phase
• voltage level (for dry-type): low or medium

General Purpose Distribution Transformers.

They are generally used for supply appliance, lighting, motorized machine and power loads from electrical distribution systems. They are either ventilated or totally enclosed, and are available with either aluminum or copper windings in standard ratings from 50VA up to 750 kVA.
Since small distribution transformers do not generate much heat, a higher proportion of theses tend to be dry-type. Dry-types are less flammable, and are therefore often selected for use when they must be located in confined spaces on a customer’s premises. Distribution transformers are used in electric power systems. The final part of the distribution system at medium voltage are the distribution transformers. Due to the low impedance voltage, this type of power distribution transformer will not substantially limit the short circuit current in the case of a fault on its secondary side. It is therefore common practice that power distribution transformers have to be type tested to their ultimate short-circuit conditions. Power distribution transformers may be oil filled or dry-filled. Distribution Transformers consist of two primary components: Core and Coil. Coil is a conductor, or winding, typically made of a low resistance material such as aluminum or copper. Copper or aluminum conductors are wound around a magnetic core to transform current from one voltage to another. Liquid insulation material or air (dry-type) surrounds the transformer core and conductors to cool and electrically insulate the transformer.
A core made of magnetically permeable material like grain oriented steel.
Distribution transformers are either mounted on an overhead pole or on a concrete pad at ground level. There is some evidence to suggest that pole mounted transformers dissipate heat more easily than pad mounted units and may therefore be more fully loaded.

What is Switchgear? Features, components and classifications

Switchgear plays a vital role in the overall power distribution and consumption system. Generally speaking, switchboards are the term one uses to designate low voltage switching whereas switchgear connotes HT usage scenarios.

The switchgear system

The term “switch” brings to mind a device that makes or breaks an electrical contact. In the industrial and LT/HT context switchgear is more complex as switchgear dealers will tell you. Switchgear is typically classified into categories like low voltage/low tension switchgear, medium voltage switchgear and high voltage-high tension switchgear. A typical system has the power components and control system with a variety of safety and monitoring features. One of the best names in the switchgear business is Larsen & Toubro. L&T Switchgears are the first choice of industries and power distribution companies for their total reliability and faultless performance.

The term switchgear refers to a collection of various devices such as:

• Fuses
• Circuit breakers
• Isolators
• Relays, coils
• Disconnect switches
• Current transformers for sensing and monitoring as well as protection

All these components of switchgear may be contained in a suitable metal cabinet that is usually earthed for safety reasons. However, HT distribution systems with large circuit breakers and switchgear are usually housed in a building.

Apart from switching on and off electricity supply, switchgear must also control power to the load, detect overload conditions and have features to automatically trip, such as circuit breakers. This protects the equipment that consumes power and it also keeps cables and switchgear protected. Switchgear may also have multiple sources of supply and automatically switch load in case one source fails.

Switchgear and protection may be automated or manually operated though the former is preferable since the automated system detects overloads and short-circuits and immediately disconnects supply thus preventing a major hazard.

Some more features of switchgear:

The household switch you are familiar with usually has air as the isolating medium since air is an insulator. However, when it comes to HT/LT applications where voltages and currents may be quite high then the circuit breakers may be oil immersed, gas or even vacuum insulated. Some switchgear makes use of the hybrid model incorporating air and gas technologies. The main reason for using gas, air or vacuum is to quench the arc caused at the time of pulling contacts apart. For instance, medium voltage switchgear operates at around 40000 volts and this high a voltage can cause quite a spark. Vacuum circuit breakers are usually employed here.

Switchgear may be classified according to voltage and current rating, by the choice of insulating medium and the interrupting rating or the short circuit current that the device can handle. Then there are further sub-classifications possible such as manual/motorized or solenoid operated as well as the transmission and distribution system. Switchgear may be purposed for isolation purposes, as load break switches and as grounding switches too in high voltage switchgear, medium voltage and low voltage switchgear.
