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…

Study of Inrush Current

The selection of over-current protection devices such as fuses and circuit breakers is made more complicated when high inrush currents must be tolerated. The over-current protection must react quickly to overload or short circuit faults but must not interrupt the circuit when the (usually harmless) inrush current flows…

Transformers Noise Level Analysis & Reduction Techniques

The subject of deciding such as the most appropriate method and conditions for accurately measuring the noise level of a transformer has been discussed in this article...

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…

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)...

“Smart Cities project will generate opportunities for Dry Type Distribution Transformers”

The area of concern is the falling tariffs within the renewable energy sector which is affecting the cost of transformers, states Manjit Singh Sethi, Local Business Unit Manager - Transformers, ABB India & Chairman, IEEMA Transformer Division in an interaction with Supriya Oundhakar…

An Overview of Superconducting Transformer Technology

Electrical energy is a major source of the entire process of evolution and modern lifestyle. This paper highlights the developments of the high temperature superconducting (HTSting) power transmission and distribution equipments such as transformer. Demand of energy, electricity generation and power transmission and distribution system require energy efficient equipments and machines...  - Hambir Singh, Muvendra Kumar Singh

Curse of Dual Certification for Distribution Transformers

There is a  conflict, the  manufacturers are requesting Govt. of India to allow  them the  compliance of one of the authorities/  agencies directive i.e. BIS or BEE  for the  same goal  of  producing Energy Efficient DTs,  and should not insist upon  as in both the cases, they have to manufacture Energy Efficient Distribution Transformers as per only one standard  IS:1180 Part 1/2014… - B Lal

Strengthening Power Distribution Systems

If we look at the huge costs of maintenance, repairs & replacements for oil type transformers spent every year, then the differential cost between oil type and dry type transformers should not be a too big amount, if it helps reduce transformer failures… - Aviral Gautama, Sailesh Purohit
