Maintenance

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...

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

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...

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

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

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

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

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

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

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

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

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

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...

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...

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
