Chandigarh, Feb 6 (UNI) Due to dense fog, there have been sudden breakdown of major 400 KV transmission lines of the Power Grid in the northern region.

Disclosing this here today, a spokesman of the Haryana Power Utilities said that with the non-availability of these major arteries, the power availability to a major part of the state had been adversely affected. This resulted into less availability of electricity from the northern grid during the last two days.

He said on the intervening night of February 04 and 05, thick fog engulfed Delhi and parts of Haryana and Uttar Pradesh, which coupled with high pollution level in some areas led to flash over on many 400 KV transmission lines of Power Grid.

As a result, about 40 transmission lines of 400 KV level broke down at different times during the night, leading to disruption of supply in major parts of Haryana and in neighboring states. Haryana Power Utilities made strenuous efforts to prevent complete blackout in the area.

He also said that the transmission system of Punjab, Haryana, Himachal Pradesh and Jammu and Kashmir was separated from the northern grid yesterday.

Due to the sustained efforts of these states, State Load Despatch Centres and the Regional Load Despatch Centres it was possible to contain the problem. However, power supply remained affected more or less in Kurukshetra, Panipat, Sonipat, Hisar and Bhiwani districts.

The supply to these areas was restored at 0930 hrs.

The spokesman said that heavy fog was again experienced today morning in the region and the transmission system, already under stress, got further stress leading to disruption of power supply in Gurgaon, Bahadurgarh, Manesar and Palwal.

However, with the combined efforts of Haryana and Power Grid Corporation of India Limited the supply was restored in phases in affected area.

He said that all out efforts were being made to minimize the outage period and consequent power cuts. The Utilities deployed about 400 employees to restore the supply system on priority basis.

He urged the consumers to bear with the situation.
