Power Quality in Telecommunication Exchanges Delivery Points

摘要

Power quality is an important subject to correctly dimension protection devices and back up power systems for next generation of telecommunication network. In this paper it is presented an overview of some power quality data obtained using integrated instruments put inside Chloride's UPS, widely distributed in the world and active for quite a few years, allow statistical evaluations to derive some important convictions about the power quality situation, which are the electrical energy parameters particularly important for the design of new generation tlc apparatuses. The article is focused on the Italian situation and in detail analyzes the mains failures for each Italian region.
