Maintenance

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

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

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…

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...

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.

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

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...

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

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...

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

- By Ranjana Konatt, Editor (Brand Positioning) On Wednesday, May 13th 2020, Finance Minister Nirmala Sitharaman announced a special scheme for the power distribution sector...

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

To prove that the transformer meets customer’s specifications and design expectations, the transformer has to go through different testing procedures in manufacturer premises... - D A Suthar

Since oil does not come in contact with external air, there is hardly any deterioration of oil over a period of time and hence such transformers are virtually maintenance free... - Mukesh D Mulchandani

On-line dielectric condition monitoring of bushing and transformer insulation is essential for managing transformer health. MONTRANO continuously monitors the condition of insulation in bushings and transformers...

A few tips which can be useful in maintenance of power and distribution transformers.

- The article is authored by Dr Iyad Al-Attar Dr Iyad Al-Attar is a Mechanical Engineer, and business innovator. He is also a Visiting Academic...

The article explores the sources of noise in Amorphous and CRGO core distribution transformers and the ways in which it may be controlled.

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...
