Power System Analysis

Build a single-line diagram, enter equipment data, and study the operating and fault conditions of your electrical network.

  • Load flow, voltage profile and equipment loading
  • Short-circuit currents and source contributions
  • Relay coordination and study reports

ENGINEERING STUDIES, PERFORMED FOR YOU

A tool for your desk.
A study team for your project.

ZeroRiskk also provides engineering study services. Discuss your network, operating question or relay event with us, and define a scope around the data and decisions that matter to your project.

A PRACTICAL PATH

Start with the question.
Build the evidence.

Whether you run the tools yourself or request a study, the starting point is the same: a clear scope and traceable engineering inputs.

01

Define the task

Choose a network study or a disturbance-record investigation.

02

Prepare the inputs

Gather the SLD and equipment data, or the matching COMTRADE files and event context.

03

Analyze & review

Examine results against your operating cases, protection settings and assumptions.

04

Document the findings

Keep the inputs, study scope and evidence together for engineering review.

LEARN BY DOING

Build your first
power-system study.

Follow the SLD Studio course with a downloadable training network and parameter worksheet. Work through drawing, load flow, fault studies, relay coordination and report preparation.
