Published by Dranetz Technologies, Inc. Below are three situations aviation teams often face, and how the HDPQ Xplorer 400 helps resolve them. Jetway keeps resetting when an aircraft connects What’s happening: During bridge movement or aircraft power-up, the 400 Hz supply dips. Sometimes it is a brief sag, other times a fast transient that trips protection.Continue reading “Practical 400 Hz use Cases for Aviation Teams”

Modeling of Overvoltages in Gas Insulated Substations
Published by Tomasz KUCZEK, Marek FLORKOWSKI, ABB Corporate Research Center in Krakow, Poland Abstract. Gas Insulated Substations (GIS) are broadly used for transmission and distribution of electric power. Due to the interactions with a network and various environmental phenomena like lightning the GIS are subjected to the Very Fast Transients (VFT). Such VFT can beContinue reading “Modeling of Overvoltages in Gas Insulated Substations”
