Short Circuit Analysis for Railway Power Supply Systems

 

Short-circuit analysis at railway power supply systems is a typical application for the Transient recording function of the Dewesoft power analyser. At the expansion of short-circuits in railway power supply systems it is often assumed that the short-circuit current is split in thirds. 

 

One third flows via the return conductor, one third via the rail track and one third in the earth. In reality, the results differs a lot and strongly depends on the ambient conditions (soil, grounding, etc.). 
 

The Dewesoft Power Analyser allows measuring the expansion of the short-circuit with automatic evaluation. Parameters like peak current, AC and DC part of the short circuit, time of the short circuit and a lot more can be calculated. Furthermore high-speed cameras and thermal imaging cameras can be connected to the system for comprehensive analysis.
