Sri Lanka: German transformer experts are due to arrive in Sri Lanka on Monday 21 March to inspect some 30 electrical transformers and recommend ways to prevent countrywide power failures after two identical transformers exploded and caught fire at Biyagama and Kotugoda substations last week, causing island-wide blackout.
The main task of the expert team will be to inspect the two transformers and assess how these isolated incidents affect the entire electricity distribution network, recommending short-term and long-term solutions, reports the Sunday Times.
According to Ceylon Electricity Board’s initial investigations, both explosions were caused by a failure in the transformers’ tap changers, which need to be replaced.
These vital transformer components cost around $1.5 million each, but the figures will be definite after the report from the expert team.
