A small case study using PSCAD

Using PSCAD software, we simulated a small example with a section of Australia’s actual power network, complete with transformers, overhead lines, underground cables, and power sources as shows in above figure. Within this model, we introduced a three phase to ground type of electrical fault for a brief 0.25-second period. The figure below illustrates the immediate impact this fault had on voltage and current levels at the fault location. This example highlights how PSCAD helps analyze power system behavior during disturbances.

PSCAD makes power-system simulation clear: build detailed models with advanced controls, run lightning-fast electromagnetic studies, and visualize results instantly. Engineers are relying on PSCAD for its accuracy, clarity, and effortless workflow.
