Highlights
The April issue of Eletricidade Moderna is online. The article “Connectors for direct current systems”, on page 20, shows that, with the evolution of the load characteristics, the discussions on the replacement of the current CA systems by CC networks are intensified. But installing DC connectors involves certain risks and requires specific solutions. See on page 24 the article “A study on the mitigation of capacitor switching transients”, in which 12 computational simulations were performed considering three solution alternatives for the reduction of perturbations, involving reactors and resistors in series with capacitor banks and vacuum disconnecting switch with system closure at zero crossing. Read on page 38 the article “Management of the consumption in installations during periods of inactivity”, which deals with hourly segmentation, considered as an adequate tool for analyzing the use and consumption of energy during periods of inactivity or reduced activity. This issue also introduces brands news “Power and distribution Transformers" and “Energy storage systems” buyers’ guides.
