Power Transformer Market worth US$ 29.91 Bn by 2020

The growth is due to the increase in HVDC transmission projects mainly in the Asia-Pacific region. HVDC, EHV, and UHV projects being undertaken for reducing transmission losses during transmission over large distances is the major growth driver of the large power transformer market.

Smart Monitoring

An in-depth analysis on how IoT based monitoring system enhances performance of distribution transformers.

Best ways to test transformer oil

Testing of oil plays a vital role in keeping transformers running efficiently and effectively. Here’s a comprehensive analysis on the different ways to test transformer oil.

Smart Transformer for Smart Grid Operation

As an integral part of the Smart Grid, smart transformers work independently to constantly regulate voltage and maintain contact with the smart grid in order to allow remote administration if needed and to provide information and feedback about the power supply and the transformers themselves.

Innovative Current Transformer Testing

This article describes an innovative solution to test current transformers at all lifecycle stages by using a sophisticated testing method known as “the modeling concept”.

Benefits of HVDS for Agriculture

Implementation of high voltage distribution system (HVDS) for agriculture consumers will result in reduction in losses, increase in energy saving and improve voltage profile.

Condenser Bushings

The article focuses on basic design changes and materials being addressed to bushing apparatus used on power transformers in high voltage substations.

CT Analyzer for Current Transformer Testing & Assessment

To keep the device’s technology at the high level required by its continuously changing working environment, the CT Analyzer has been reworked once again.

ABB Launches World’s First Digitally Integrated Power Transformer

The ABB Ability™ Power Transformer, unveiled at the 2018 Hanover Fair, in Germany, will be the world’s first integrated solution for digitally enabled power transformers, fundamentally changing the transformer paradigm.

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...

Smart Transformers for Energy Sector

The smart transformers are used to provide additional flexibility to control power distribution networks, thereby, facilitating the smooth conversion of AC to DC and DC to AC, as per requirement. Smart transformer caters to a wide variety of applications, ranging from alternative power generation to traction locomotives, power grid and electric industries, and others…

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...

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…

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…

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…

Smart Maintenance of Power Transformers

State-of-the-art test systems and a smart software solution for diagnostic testing, condition assessment and easy data management help to evaluate the status of a power transformer faster and more reliably than ever before…

Common Errors While Designing an Electrical Protective Scheme

If the selection of inappropriate specifications switchgears go unnoticed, it may jeopardize safety of man and machines both. Therefore, utmost care is required, while designing an electrical protective scheme as far as selection of CTs of correct specifications, switchgears, etc is concerned.

Diagnostic Testing On Transformers

Performing a range of standard electrical tests on a regular basis has proven to be an effective way of gaining reliable insight into the operating condition of transformers. But, this has been a time- and cost-intensive job in the past. A true three phase test system can really make a difference.

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)...
