A number of areas in the city on Wednesday faced power cuts for varying durations due to disruptions in the distribution network caused by kite-flying.
A BSES official said 14 incidents of tripping of power supply line were reported from various parts of the city.
The affected areas were Mayapuri, Janakpuri, Mukherji Park, Udyog Nagar, Paschim Vihar, Nand Nagari, Yamuma Vihar, Karkardooma, Minto Road and Preet Vihar.
BSES had issued an advisory last week, asking people to fly kites carefully and guard against disruption in power supply.
Officials said power cuts happened after kite strings got entangled in transmission lines. Several such incidents had been reported in the run up to the Independence Day.
Can affect many residents
According to officials, tripping of just one 33-66 KV overhead line can disrupt supply to over 10,000 residents. Metal or glass-coated manjhas (threads) are good conductor of electricity and they lead to tripping.
There is also a risk of electrocution.
Last year, at least 23 incidents of tripping of power supply on Independence Day due to kite-flying were reported.
