Maintenance

With a view to achieving its goal to become a decentralized global technology company, recently ABB has disinvested 80.1 per cent of its Power Grids...

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...

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...

If an LTC fails, the entire transformer will shut down. Transformer failures can cost your utility millions of dollars, adding overtime pay for workers...

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…

Due to use of better grade materials and optimum design, sudden failures are reduced along with lower cost of maintenance, leading to increased life expectancy. These benefits add up and balance against the inevitable increase in purchase cost – as additional copper in the windings and better materials in the core will be used in the manufacture of high efficiency transformers... - S V Varadarajan

Periodic inspection of power transformers and their accessories contributes to their trouble-free operation. These inspections may identify nascent problems before they become serious enough...

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…

When unexpected results are obtained while testing the dielectric breakdown voltage of transformer dielectric fluids, the cause can often be traced to inadequate preparation...

A significant proportion of failures in electrical devices result from the deterioration of insulation. The implementation of routine, straightforward tests, along with prompt maintenance...

Utilities and transformer manufacturers focus on the design and manufacture of environmentally-friendly transformers that are nonhazardous while offering improved life cycle costs with minimal maintenance. These transformers offer reduced carbon footprint, reduced levels of pollution (water, soil, noise), enhanced lifecycle costs, enhanced product lifetime, and enhanced fire safety…

Generator, transmission and distribution transformers are some of the most critical and expensive assets in a power network. - Setu Vora

The life-expectancy of Power Transformers, is assumed to be 35-40 years. However, there is no literature expressively quantifying the same. Unforeseen failures of old...

To aid in the organization of a corporate or personal library, Megger is introducing a comprehensive series of Transformer Life Management bulletins that broadly cover the fundamentals of managing the life of a transformer.

Causes of transformer failures include imperfection in design and environment. One of the main causes of failure of a transformer is the insulation failure. - D M Srinivasa, Dr. Usha Surendra

A Distribution Transformer (DT) is an electric machine that works on the principle of electromagnetic induction, and is used to transfer electrical power over...

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

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

A distribution Transformer does not get much attention after installation — until something goes wrong. Getting the selection and maintenance basics right from the...

This article explains how 'condition monitoring' of transformers ultimately increases the life expectancy and renders trouble free service to the customer – and helps economic development of the country... - S Kundu
