Therefore, Yanotti suggested that users make “claims to distributors” because, probably, for these damages it is necessary to “do manual repair” regardless of what happened in the high voltage lines. which is not what happened yesterday under high tension. “Today we are going to have people without service.

Yesterday, the company Transener declared at 7:50 p.m. the “end of the risk” due to the massive power cut which originated in a field fire which from 3:59 p.m. “disturbed a 500 kw high voltage line that connects Campana to General Rodríguez.” In the last hours, the authorities have sought to identify those responsible for the incident, which they believe was sabotage.

Among the effects of the outage, one of the generators which left the interconnected system as a safety measure was Atucha I, the nuclear power plant located a few kilometers from the fire. Typically, in the event of an incident of this nature, the power stations have backup devices that disconnect them when traffic on the national network is obstructed.

As the Undersecretary explained Santiago YanottiAtucha will take time to return to 100% operational capacity.

“Atucha worked very well but now only injects inside 48 hours. It does not go out suddenly, but gradually with systems of backup, it lights up little by little and after it enters (in the interconnected system), the power it injects requires a few days until it reaches 100%, but the important thing is that there were no failures”, a- he mentioned in a comment to GlobeLiveMedia.
