Highlights
The June issue of Eletricidade Moderna is online. The article “Systems and applications of DC experience a rebirth”, on page 22, shows that the use and storage of renewable energy and the demand for energy savings impose new requirements for designing and operating data centers and office buildings. As the rapid development of information and telecommunication technologies requires flexibility of physical infrastructure, full DC application is a possible solution to this challenge. See on page 28 the article “Fire safety lights - comparative analysis - Part 2”, where the costs of a hypothetical example are quantified, making it possible to compare relative costs for general applications. Furthermore, on page 36, the article “Overcurrent protection with undervoltage monitoring”, focusing on the adaptation of protection functions used in electromechanical relays using the standards of IEC 61850. This issue brings also the new “Cable & wire accessories” buyers’ guide.
