Maintenance

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...

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

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

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…

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

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...

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...

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

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

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

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
