The electrical devices that are operated at high voltage then chances of losses are really higher and transformers are no exceptions. When excessive heat is generated inside transformers then it will cause sudden temperature rise that may disturb internal structure of device. For premium efficient transformers, chances of temperature rise are really low. It also depends on winding materials used inside transformers that control transformer load ratings and its operations too.
Overload voltage Capacity and rating
Transformers are divided into different categories like low voltage transformers, high voltage transformers, dry type transformers or liquid filled transformers. Temperature rise for all of these transformers is also different and transformer manufacturers India have to design products accordingly. Temperature rise values should be set carefully without causing any damage to transformer insulation or without affecting its overall life.
This is always good to obtain real load or no-load losses details in watts from leading transformer manufacturers India otherwise it may cause problem later. In few cases, when complete details are not available then temperature rise is considered rough indicator for transformer efficiency. The transformers with high temperature rise generally results into low operating efficiency and high transformer losses.
For premium efficient transformers, chances of heat wastage are generally less in earlier stages. Premium transformers not only account for how much heat has been generated but how much heat has been removed during high temperature rise or transformer losses. In case, transformer you are installing on to your industry location is not energy efficient then extra cooling devices are attached with the transformers. Extra cooling devices result into extra cost that is completely annoying.
SO, it is clear standard transformers may have low initial investments but shorter paybacks. At the same time, energy efficient transformers are little bit expensive but assure attractive paybacks in long run.
Transformers are virtually essential for all kind of commercial building, malls, hospitals etc. For different industries, client generally required differently sized transformers that can suit their requirement the best. People always look upon durable products are reliable and highly cost effective too.
For certain time period, premium efficient transformers may cost extra than your budget but they are generally effective in long terms. Moreover, selection of right transformers largely depends on properly sized transformer and its capacity. For efficiency, you should look upon both transformer losses and winding materials.
In simple words, transformer losses are divided into two categories – core losses and coil losses. The core losses are caused due to laminated steel core that is energized due to high magnetic current flowing inside. Energy continues to get wasted for the time transformer is energized. Losses generally vary with transformer size and type of core selected. This is the reason, Power transformers manufacturers focusing on size of transformer in this blog.
Load losses are generally created inside primary or secondary coils and this is the result of winding material resistivity. So winding material should be copper that can make a difference to losses.
When requirements are not clear, engineers may get confused about actual loading requirements that will be placed on unit. In this case, transformer may get damaged when load exceeds the defined limit. So, it is necessary to discuss on project requirements carefully to ensure minimum losses inside core.
Once engineers are sure on voltage load requirements then size of transformers are also set accordingly. Large sized transformers for small transformers may result into heavy losses and unwanted project costs. A table is also designed to check or verify different specifications of transformers that suits particular application or industry the most.
Consider one transformer has been installed around 40 years back but it meets all necessary clearances and maintenance standards. After careful observations, it was concluded by experts that transformer is still in proper condition as required.
The unit was operated at high temperature but surface of transformer was not really hot. Obviously, this transformer was less energy efficient than current ones but only energy efficient characteristics is enough to consider for replacement for old transformers. Do you need to consider anything else too?
Each transformer has certain losses associated with it. Few transformers have larger losses while others have negligible. You have to pick the best product that suits your requirements the most. For this purpose, energy saving light transformers has to be tested on different temperature and loadings. One performance sheet is prepared by team that is reviewed by clients for final decision.
The modern transformer units are more protected and efficient than traditional ones. Energy losses have also minimized with continuous practice and efforts of expert team. The losses are generally calculated in the form of heat that is cooled by HVAC system further. Fans, chillers or other utilities are also added to the product to balance heat inside transformers. TO know more on transformers and to get energy efficient products, it is always better to discuss with leading manufacturers or suppliers in the transformer industry.
When transformers are installed indoor then it needs proper enclosures for best protection schemes. For indoor installation, you are advised to use aluminum windings because space is not an issue and aluminum windings are generally more cost effective than other materials. Further, transformer should also be sized properly to avoid significant losses and heat releases.
You should also consider high current protection for energy saving light transformers in selective coordination with other components. The transformers should be reviewed from different prospects – its damage curve and transformer inrush. SO this is the right time to move out in transformer world and check for highly efficient and protected energy efficient transformers.
