Dubai Electricity and Water Authority (Dewa) is set highlight the services and mechanicsms used in transformer oil tests at its ‘Transformer Oil Test Laboratory’  at a leading exhibition in Dubai, UAE this month.

The Water, Energy, Technology and Environment Exhibition (Wetex 2015) will run from April 21 to 23 at the Dubai International Convention and Exhibition Centre.

The laboratory is operating with high-tech certified technologies to improve the efficiency and effectiveness of maintenance, which supports power transmission by providing analytical services and service-evaluation systems, said a statement.

Monitoring transformer oil helps maximise the operational lifespan of the transformer, which is reduced significantly if undiscovered faults inside the equipment start to occur, it said.

Saeed Mohammed Al Tayer, managing director and chief executive officer of Dewa, said: ” Dewa constantly strives to make our customers happier by adopting the most innovative mechanisms in the production, transmission, and distribution of energy. This supports our vision to become a sustainable innovative world-class utility and our commitment to become a global role model in performance, efficiency, productivity, and excellence in providing reliable and available electricity and water services according to the highest international standards.

“The internationally-accredited laboratory in Warsan provides transformer oil testing services for Dewa and other local and regional customers from the commercial and industrial sectors, according to the highest international standards and specifications.”

"Dewa has achieved outstanding results in efficiency and reliability that surpass even the private sector. Dewa increased efficiency of energy generation by 22 per cent between 2006 and 2014, using the latest technologies and adopting technological innovations. Dewa has surpassed leading European and American companies by reducing losses in power transmission and distribution networks to 3.26 per cent, compared to six to seven per cent in Europe and the US,” said Al Tayer.

“Water network losses decreased to nine per cent, compared to 15 per cent in North America, achieving global results in reducing water losses. Dewa's results are among the best internationally for customer minutes lost per year. Dewa's figures reached 4.9 minutes, compared to 15 minutes recorded by leading utilities in the European Union," added Al Tayer.

The laboratory checks the oil used in all kinds of electric power transformers. This oil also insulates parts that should be beyond the reach of electricity, and it is necessary that this oil remains at a fixed temperature in all circumstances, making it imperative to carry out continuous testing to ensure the stability and quality of the oil used to cool the transformer, said the statement.

Periodic testing of insulation oil quality is one of the most important factors to ensure safety of transformers, it said.

It performs over 25,000 tests annually and covers all Dewa’s power transformers in all sections, including over 40,000 units in production, distribution and transmission.

It will also help Dewa and its customers to avoid any potential malfunctions during the operating lifespan of the transformers. This in turn, reduces non-planned outages in an effective way, it added. - TradeArabia News Service
