Transformers are simple, yet sophisticated devices which play more than just a crucial part in our electrical system. Without the development and use of transformers, we wouldn’t be able to live the same effortless lives that we are living. Transformers are often overlooked but these amazing machines play a vital role in ensuring and keeping our electrically charged digital world up and running full pace. Transformers can also be differentiated into various types as the tasks that transformers may need to do vary according to the situation they operate on. Don’t be surprised when we tell you that we use various types of transformers in Nepal too, according to the need and surroundings it has to work in.
Power transformers and distribution transformers are two of the most common transformers used in Nepal. Among these two types of transformers, distribution transformers are the ones that are used to safely circulate the electricity to the people, their homes and offices. The high voltage electricity that are sent from power plants will not be suitable for common uses in homes and offices. It is the distribution transformers that helps in converting high voltage electricity to lower voltage electricity suitable for common use. Distribution transformers have a straight forward function of providing isolation and not only acts as but are a type of step down transformers.
Distribution transformers make us, our homes and work places safer and we should be grateful towards distribution transformers. Such transformers in Nepal are also found in every part of our industrial, commercial and residential areas. We should know about these versatile and useful devices, their importance and know about them to keep them in top condition and make the most out of them.
Uses and Application of Distribution Transformers
Distribution transformers are probably the most commonly and extensively used transformers. These types of machines are used in all types of assorted fields such as consumer and domestic transformers, wind mill power transmissions, electricity boards, industrial hubs and even in a big area having many properties, houses or buildings inside a perimeter. Few of its common applications are listed down as follows
Transmission lines
After converting high voltage electricity to low voltage electricity, the current is passed for use through transmission lines. Due to this, several power issues that may arise will be prevented. Voltage drops that can seriously harm our electric devices and electric systems can be prevented as power transmitted through transmission lines is equal to product of voltage and current.
Safety alarm
Distribution transformers also act as an alarm in many cases where there might be hazardous voltages passing. These devices will let the power stations know if any sort of abnormal activities or flow or power is occurring then necessary actions can be taken to prevent the damages that may occur.
Sensitive electric equipment
Most electric equipment are sensitive and prone to damage when they are put against unsuitable voltages. Distribution transformers act as the savior to these volatile devices and offer them protection. Transformers avert excessive voltages to pass through the electric systems allowing these devices to work in a safe environment.
Test and control systems
Transformers are used for testing and also helps in enabling control systems to function properly. Transformer turn ratio tests, power factor tests, resistance and polarity tests, phase relation tests and oil tests are carried out on transformers. By conducting these tests, we can find out the electrical, thermal and mechanical suitability for the systems where they will be used. The control systems also monitors and carries out the temperature rising tests which makes the device more reliable.
Telecommunications
You may not know this but transformers are widely used in telecommunication sector. In telecommunications, transformers are used in operations which require high bandwidths along with very fast switching speed. There are a lot of transformers to choose from according to the task in hand. They are DSL, xDSL, E1, ISDN, LAN, WAN, ATM and Modem transformers.
Lighting plants
It is a well-known fact that transformers are used in lighting plants for the generation of power. The power generated is then used for basic commodities. Without transformers, we won’t be having all these facilities and won’t be able to carry out even the basic tasks like using lights, fans and other electrical tasks and devices.
Classification of distribution transformers
Oil cooled transformers are smaller and also more efficient. Oil cooled units work on and consume less power and also they don’t create much problems in the environment. These transformers will also be able to handle heavy loads, so high voltage applications can be carried out using oil cooled transformers. Oil cooled transformers are used outdoors due to possible leakage which pose fire risks, but are more friendly.
Dry units are very resistant to chemical contaminants and do not require frequent maintenance like in oil cooled transformers. However, dry type transformers generally are a bit louder and produce more noise than oil cooled type. Dry transformers are designed to handle small to medium voltages making them ideal for smaller applications. Hence, dry type transformers suitable for use in or near buildings, infrastructures or properties. Dry transformers are less flammable and pose less fire risks, making them ideal for commercial as well as residential areas.
Distribution transformers play a huge impact in the overall efficiency, reliability and network’s cost. Hence, choosing an energy efficient distribution transformer is absolutely crucial to gain optimized load conditions, service, and ample benefits for both utilities as well as their customers. Today, it has even become a regulatory requirement to install a distribution transformer that gives minimum energy loss and lesser pollutants in order to raise awareness and to protect the environment.
Use of distribution transformers in Nepal is also increasing day by day as people are starting to know about its advantages and also its outstanding capabilities of surviving overloads helping us to conduct basic and simple electric tasks and making our lives simpler and easier.
