Maintenance

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

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

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...

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...

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

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...

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 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

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

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…

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...

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

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.

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...

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

- 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...

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.
