Consumers have also complained of low voltage situations, which can cause damage to household appliances. The Power department admitted that the voltage has been fluctuating at various points in the last 10 days. “When the load increases suddenly, the voltage dips. Because of the delay in monsoon, motors are running overtime in states like Punjab and Haryana where the harvest season is on. In other northern states, increased use of air-conditioners is contributing to the load. Given the situation, when the load reaches a certain point, the voltage dips automatically to prevent the Grid from damage,” the Transco official said.
