Rome, a first example of perceived power quality of electrical energy: The telecommunication point of view

A monitoring of power quality parameters it is been effected inside four medium/low voltage transformer rooms of telecommunication power substations of the biggest Italian telecommunication society. The measurements have been realized by means of an appropriate self-made instrument that samples the three-phases with neutral lines of the mains for a total period of about two years. By the analysis of the parameters it is possible to determine which are the power quality parameters which the society is more sensible, so to suggest which are the parameters to monitor and to ask with more quality to the energy supplier society.
