Jomotshangkha Dungkhag under Samdrupjongkhar Dzongkhag, located at the south-eastern corner of the country, shares its border with Assam and Arunachal Pradesh in India. The three gewogs of the Dungkhag, namely Langchenphu, Serthi and Lauri had to stay without electricity supply for 18 days starting from 10th September 2020. The supply could be restored only on 27th September 2020. The supply interruption affected a total of 2645 customers.
The electricity to Jomotshangkha Dungkhag is supplied through a 33 kV line emanating from the 132/33 kV substation in Phuntshothang (Bhangtar). With over 260 km in length and traversing through rugged terrain, dense vegetation and several river on the way, the line has 175 transformers connected to it.
When the above line tripped on 10th September 2020 at around 9:22 pm, the electricity supply to all three gewogs under Jomotshangkha got interrupted. Early morning on the following day, two teams were dispatched for patrolling the line, one from Phuntshothang and other from Jomotshangkha to find out the fault. The patrolling effort was hampered in the initial two days due to continuous downpour and swollen rivers and extra reinforcement had to be made.Read more »
