PQ Terms & Definitions

Published by Dranetz Technologies, Inc. Website: Dranetz.com PU (Per Unit) Explained PU stands for Per Unit. It is a term that electric utility engineers frequently use, and it was incorporated into IEEE 1159. PU is the percentage formed by dividing the actual voltage by the nominal. For example, a sag to 0.8 pu on a 480V circuitContinue reading “PQ Terms & Definitions”

Non-Standard Solutions for Supports of High Voltage Overhead Lines in the Aspect of Landscape Protection and Electromagnetic Field Impact

Published by Marek JAWORSKI, Politechnika Wrocławska, Katedra EnergoelektrykiORCID. 0000-0002-6537-050X Abstract. The article presents issues related to choosing an overhead line route in the aspect of landscape protection. The possibility of using nonstandard supports, which task is to replace traditional electricity pylon and better integration into the surrounding landscape, was pointed out. The paper describes theContinue reading “Non-Standard Solutions for Supports of High Voltage Overhead Lines in the Aspect of Landscape Protection and Electromagnetic Field Impact”
