Overvoltage Induced in Overhead Power Lines by nearby Lightning Stroke
Published by Grzegorz MASŁOWSKI, Robert ZIEMBA, Tomasz KOSSOWSKI,Rzeszow University of Technology Abstract. The results of simulations of overvoltages induced in the overhead transmission line, caused by nearby lightning stroke are presented. Calculations were made using the LIOV module implemented in the EMTP-RV program. The influence of the distance of the lightning channel from the lineContinue reading “Overvoltage Induced in Overhead Power Lines by nearby Lightning Stroke”
Noise and Vibration Analysis of a Distribution Transformer
Published by Dániel MARCSA, eCon Engineering Kft., Hungary Abstract. Transformer noise is a significant contribution to unwanted ambient noise, especially in the vicinity of the electrical transmission facility. It is therefore very important to get to know the mechanism of noise generation of the distribution transformer. As outcomes of this work, a finite element basedContinue reading “Noise and Vibration Analysis of a Distribution Transformer”

Power Quality – IEEE 519-2022
Published by Comsys AB, website: comsys.se, ADF Technology: Power quality – IEEE 519-2022 A commonly used and very important standard is IEEE 519-2022 (previous versions IEEE 519-1992 and IEEE 519-2014). The standard, among other things, puts two requirements on harmonics; and absolute maximum THDU level, and a variable maximum TDD level. All limits are appliedContinue reading “Power Quality – IEEE 519-2022”
Tropical Climate Effects on Corona Power Losses on 275 kV Transmission Lines in the South Sulawesi System
Published by Ikhlas KITTA, Salama MANJANG, Ida RACHMANIAR, Faris MARICARElectrical Engineering Department, Hasanuddin University, Indonesia Abstract. Electricity losses are very dependent on electric current and loss of the corona phenomenon. It is very clear that losses depend on network parameters, load behaviors and climatic factors. South Sulawesi is a tropical climate. This sector must beContinue reading “Tropical Climate Effects on Corona Power Losses on 275 kV Transmission Lines in the South Sulawesi System”
