Jan 21, 2008 (LBO) — Power supply to most parts of Sri Lanka failed as a transformer in a transmission line just outside the capital burst in the early hours of Monday, officials at the state power utility said. A current transformer in the Kotugoda grid substation had burst tripping off the adjacent Biyagama substation which received power from the generation system in the Mahaweli river system setting off a chain reaction, a Ceylon Electricity Board (CEB) official said.
However, some generators in the Mahaweli complex and systems in areas like Badulla remained energized, and engineers were quickly restoring power to the country.
Sri Lanka has experienced island-wide blackouts earlier.
The grid failed in the early hours of December 07 after a thermal generator tripped .
Power failed island-wide on May 10, 2007 and also on April 15. .
