Smriti Kak Ramachandran Discoms asked to ensure the Capital's residents are insulated from cuts caused by frequency problems "There is no reason why paying consumers should face power cuts' NEW DELHI: The Delhi Government's Power Department has asked the power distribution companies in the city to speed up installation of under-frequency scheme to ensure that the residents are insulated from power cuts caused by frequency problems. The Department has asked all three discoms -- NDPL, BYPL and BRPL -- to speed up the process of installing under-frequency schemes at all 66 kV, 33 kV and 11 kV sub-station systems. "The scheme should have long been in place but the discoms are yet to implement the same. We have now asked them to take action on this front in the next few weeks, failing which Delhi Transco will file a petition with the Delhi Electricity Regulatory Commission to issue a directive to the discoms to comply with the orders,' said sources in the Power Department. Implementation of the under-frequency scheme is made mandatory in the connectivity code issued by the Central Electricity Authority. "There is no reason why paying consumers should have to face power cuts. If the under-frequency scheme is operational at the 11 kV level, then it becomes easier for the discoms to insulate the paying customers from power cuts. At the moment, the scheme is operational at Transco's 66 kV sub-station level,' said sources. Power discom NDPL claimed that technical trials are currently being carried out and the company will soon be ready to implement the scheme. BYPL and BRPL, on the other hand, are still working on installation of the scheme at the 66 and 33 kV sub-station levels. A company official declining to comment on the time frame for implementation of the scheme said: "As far as implementation of the scheme on the 66 kV and 33 kV levels is concerned, we have covered about 50 per cent of the area.' "Discoms have to plan for installation of under-frequency relays and ensure improvement in the distribution system to reduce frequent fault tripping and their impact on the transmission system,' he added.
