Reduction Of Losses
Technical losses in Distribution Transformers (DTs) occur because of the physical nature of the equipment and infrastructure of the power systems, i.e., I2R or copper loss – in the conductor cables, transformers, switches etc., High Technical Losses (No Load & Load losses) persist in DTs of all major utilities across India – and their losses are very high when compared to the Ideal losses for the same capacity...

Losses in Distribution & Transmission Lines
It is fact that the unit of electric energy generated by power station does not match with the units distributed to the consumers. Some percentage of the units is lost in the distribution network. This difference in the generated & distributed units is known as transmission and distribution loss…
Easing Multi-function Testing
There is only one instrument to unpack, power up and configure; the same cable set is used for a whole range of measurements, so the connections only need to be made once; and, when carrying out a range of tests, users of multifunction instruments move quickly and easily from app to app, rather than having to go from instrument to instrument... - Peter Fagerström
Fault Level Role in Selection of Protective Equipment in Power System
Almost after a decade, US economy on rising trend, a very good news for all of us. India is also an emerging economy, where power sector has to play crucial role. - Aqeel Ahmad
Smart Transformers Market worth USD 2.43 bn by 2022
The global market is set to witness a significant growth due to increasing emphasis on alternative energy production across the globe, digitalization of power utilities, and huge investments in smart grids and energy systems...
Overvoltage Mitigation Techniques for PV Grid
In this case study, the authors have reviewed the conventional techniques used to mitigate the overvoltage problem and observe that they have several disadvantages. So, it is suggested a novel technique that relies on a minor modification made to the secondary windings of the distribution transformer: an extra tapping is pulled out from each of the secondary windings into a separate PV junction box which is the modified Point of Common Coupling (PCC)...

Towards Making Resilient Grid
GE Research and Prolec GE have teamed with Cooperative Energy to develop and install the world’s first flexible large power transformer at the utility’s...
Preventing Failure
Selection of the Circuit Breaker has to be done carefully, so that it does not allow the transformer to exceed the permissible winding temperature. The built-in Bi-metallic strips mounted in the Circuit Breaker, located below the top oil, achieve the temperature sensing function. The circuit breaker thus provides Thermal matching with the transformer & protects it against over loads... - C.V.Govinda Raju
How To Achieve Transformer Reliability
Transformer failures can potentially lead to unplanned power outages, in addition to costly and time-consuming repair and replacement. - Dr. Murhari Sopanrao Kele, Chairman-cum-Managing Director, Tripura State Electricity Corporation Ltd

Aspects Of Loss Reduction
Though Distribution Transformer (DT) technical loss reduction can also be achieved through replacement of the DTs altogether, the cost of new DTs do not justify the savings from loss reduction...
Reducing Stray Losses in Transformer
This article explains how stray losses in the transformer play a vital role in increasing the total losses of transformer and also suggests how the same can be reduced significantly to lowest most value by using magnetic shield which ultimately increased the life expectancy of transformer…
