Power Systems Technical Articles

Our experts continuously work on power systems problems, and we share solutions with Practical Reference Articles.

The main topics are earthing system modeling, power cable ratings, HV/LV electrical design, protective device coordination, and arc flash studies. We cover IEC and IEEE standards.

Sign up for my email newsletter and I will send you the latest technical articles as they are released – Jayson Patrick.

Derating of 400 kV Buried Cables from Ventilated Trough

New 13 kV power circuits will be installed in an unfilled trough with ventilated covers. These new circuits will cross with existing buried 400 kV cables at approximately 90 degrees with a continuous current rating requirement of 1136 MVA (1640 A) per phase for all seasons.

Comparison of SafeGrid with XGSLab and CDEGS Results

We have benchmarked our SafeGrid Earthing Software results for a 60 x 60 m grid against well-known software XGSLab™ and CDEGS™. We show that the results for grid resistance in multilayer soils up to 5 layers are virtually identical.

Soil Frequency Dependency During Lightning Strikes

The effects of lightning strikes on earthing or protection systems designed to IEC 62305 can be modelled using an equivalent single frequency from 25kHz up to 1MHz which gives similar results to a time-domain approach. This article provides the frequency and current values to be used for modelling lightning.
