DTL develops disaster resilient infra, moving towards smart grids

Friday, 06 December 2019 | Staff Reporter | NEW DELHI

Delhi Transco Limited has developed disaster resilient infrastructure and has retrofitted existing infrastructure for resilience during the last few years and it is also moving towards smart grids, said Padmini Singla, Chief Managing Director of Delhi Transco Limited (DTL).

Singla was speaking in a global symposium organised by ‘Special Centre for Disaster Research’, Jawaharlal Nehru University.

“The smart grid concept integrates 21st century technologies with the 20th century electrical grid.

In Delhi, works are being done towards making the our grids smart and are using new technologies such as automation, intelligent monitoring, control and communication, information technology system  which enables information flow  in a controlled manner on real time basis.

Recalling the incidents of 2014 when Delhi and its adjoining areas were badly hit by high storm due to which eight towers of 220 KV were toppled down and the power supply in some part of the city was affected for one or two days, she said that to deal with such situations Delhi Transco Limited has procured ‘Emergency Restoration System’ (ERS). 

ERS is a temporary tower which is erected pending permanent repair of the damaged tower.

She further added that the tripping of power line due to fog has also been a matter of concern for Delhi Transco in the past.

The dust and other pollutant gather on the insulators and when it is moist with the fog, the line trips due to short circuit resulting in long power cut.  In order to deal with the problem of frequent power cut, Delhi Transco has replaced all the porcelain insulators with polymer insulators to avoid any further eventuality in foggy condition.
