Computer Aided Design of Transformer Station Grounding System Using CDEGS Software

Acta Polytechnica, 2004
This paper presents a computer-aided design of a transformer station grounding system. Fault conditions in a transformer station can produce huge damage to transformer station equipment if the grounding system is not designed properly. A well designed grounding system is a very important part of the project for transformer station design as a whole ...

Insights into cucumber (Cucumis sativus) genetics: Genome-wide discovery and computational analysis of the Calreticulin Domain-Encoding gene (CDEG) family. [PDF]

Saudi J Biol Sci
Cucumber is an essential vegetable crop throughout the world. Cucumber development is vital for accomplishing both quality and productivity requirements. Meanwhile, numerous factors have resulted in substantial cucumber losses. However, the calreticulin domain-encoding genes (CDEGs) in cucumber were not well-characterized and had little function.

Measurement and calculation method of substation grounding system parameters based on CDEGS

Journal of Physics: Conference Series, 2022
Abstract Indoor substations are often located in areas with intensive power consumption, and its grounding design has become a very important task. In this paper, the whole process of grounding design is studied from the grounding resistance measurement obtained in the early geological exploration to the final grounding resistance, touch

Design of distribution substation earth grid in high resistivity soil using CDEGS [PDF]

2014 IEEE 8th International Power Engineering and Optimization Conference (PEOCO2014), 2014
Design of distribution substation earthing grid can be very challenging in high resistivity soils especially in two layer soils where the top layer resistivity is lower than the bottom layer. This paper presents the design of a distribution substation earth grid using Current Distribution Electromagnetic Field Grounding Soil Structure Analysis Software

THE Simulation Study of DC Grounding Electrode Based on CDEGS and ANSYS

Journal of Physics: Conference Series, 2018
When the UHVDC project was put into operation, grounding electrode grounding current may affect the transformer in the substation near the pole, it will cause transformer DC bias saturation, which leads to higher transformer temperature rise, too high harmonic and reactive power consumption, which will cause transformer damage or power grid blackout ...

Electromagnetic Field Calculation of Transformer Station 400/110 kV Ernestinovo Using CDEGS Software

Journal of electrical engineering, 2007
This paper presents calculations of the electric and magnetic fields of complex busbars, transformers and transmission line structures at the transmission power station 400/110 kV Ernestinovo. By constructing and bringing the TS 400/110 kV Ernestinovo in operation, it was expected that electric and magnetic fields would arise within and outside the ...

Research on the Effects of DC Grounding Electrode of Yanmenguan Converter Station on the Earthing Network of Substation and Windfarm Based on CDEGS Software

Journal of Physics: Conference Series, 2021
Abstract It is of importance to assess the electromagnetic influcence of HVDC converter station on buried metal facilities of AC substations, fossil-fuel plants, windfarms and pipelines. Electromagnetic interference model was established based on the experimental measurement of soil resistivity and actual physical location.

Evaluation of steady-state ground resistance by field measurement and CDEGS computation

Bulletin of Electrical Engineering and Informatics
In addition to the soil resistivity and size of the grounding system, grounding system configuration can influence the steady-state resistance (RDC) of a grounding system. The RDC of four to six configurations in three distinct soil conditions (sites 1 to 3) is measured using the fall-of-potential method and computed using the current distribution ...

Palynological and palynofacies analysis of early Silurian shales from borehole CDEG-2a in Dor el Gussa, eastern Murzuq Basin, Libya

Review of Palaeobotany and Palynology, 2012
Abstract This work presents palynological and palynofacies analyses from early Silurian Tanezzuft Formation shales recovered from core material of borehole CDEG-2a drilled in Dor el Gussa at the eastern margin of the Murzuq Basin, southern Libya. The material has yielded well-diversified palynomorph and chitinozoan assemblages and organic matter from
