The analysis was based on a list with 54 verification items and on an inspection of the electrical installations in ten substations. According to the items used, here was an average of 65% of adequacy . Besides, 20% of the verified items partially fulfilled the standards. If those items were adapted, the evaluation of the substations would be considerably improved.
