Trees, storms, etc.
If there is a harsh reality that we have in Brazil, in the electricity sector, it is the difficulty of learning from problems that have been established for a long time.
Trees and branches that always fall on electrical grid causing ("unplanned") interruptions due to rain and wind are a systemic phenomenon that lasts for decades.
Our regulations and laws are great on paper. They foresee a maximum of 20 hours/year of interruptions. In real life, in the neighborhood where I live in the south of S?o Paulo, the observation is that there are interruptions with an extra zero!
All institutions involved in this matter are truly incompetent and unprepared.
After all, this is not an episodic, “force majeure” case. It's all strictly predictable.
When will we become aware of this reality and in the same vein, when will we demand the preventive attitudes that established practices of good engineering recommend?
