BOOM! Transformer repair expected to take two weeks in Heredia

The transformer that blew up Saturday in Heredia was not one of the white cylinders found on a utility pole. This was a  138,000-volt device at the San Miguel substation in Santo Domingo de Heredia. The Instituto Costarricense de Electricidad said that repairs would cost 81 million colons, about $153,000.

The outage involved customers of the Compañía Nacional de Fuerza y Luz and those of  Empresa de Servicios Públicos de Heredia. Service was out from about 7 p.m. Saturday until 1:30 a.m. Sunday, the state power company said.

The explosion damaged other parts of the substation, and repairs will be completed in about two weeks, estimated the Instituto Costarricense de Electricidad.

Here are the remains of the exploded transformer.
