ONE NETWORK MODEL
From single-line diagram
to engineering results.
Power system analysis examines how a network operates in normal and fault conditions. SLD Studio connects the electrical diagram, equipment data and study cases so you can review the network in context.
Load flow analysis
Review bus voltage, angle, active and reactive power, branch current, losses and equipment loading. Compare operating cases and identify voltage or loading concerns.
Short-circuit analysis
Study fault currents at selected locations, examine source contributions, and review current through interrupting devices against the supplied equipment data.
Relay coordination
Review time-current relationships and grading for the modeled protection devices. Examine proposed settings and operating sequences with the project’s protection requirements in mind.
Operating scenarios
Change service states and study cases to examine different network conditions. Check topology and missing parameters before interpreting results.
Reports & drawing exports
Keep the diagram, input schedules and study outputs available for review. Export supported drawing and report formats from the workspace.
PREPARE A USEFUL MODEL
Good inputs make
results reviewable.
Start with an up-to-date single-line diagram and the operating case you want to investigate. Required data varies with the study and equipment type.
Network & sources
Voltage levels, frequency, connectivity, grid fault data and generator information.
Equipment
Transformer ratings, impedance and grounding; cable or line data; motor and load information.
Protection & scenarios
Device ratings, CT/VT data, relay settings, normal and contingency operating arrangements.

A WORKED PRACTICE NETWORK
Learn the complete
SLD Studio workflow.
The 16-chapter tutorial follows a training network through model preparation, operating studies, fault studies, coordination and exports. The model uses provisional training inputs.
Inspect the network
Download the practice SLD and review equipment schedules in the worksheet.
Follow the course
Open SLD Studio and use the tutorial button to follow the chapter relevant to your task.
Check the results
Compare cases and use the worksheet’s practice checks. Replace provisional values before applying a model to a real project.
BEFORE YOU BEGIN
Power system
analysis questions.
Can I run power system analysis online?
Yes. SLD Studio provides a browser-based drawing and study workspace. Open the tool to create a network, supply equipment parameters and review the available study options. Account and payment requirements are shown in the workspace.
What is the difference between load flow and short-circuit analysis?
Load flow studies the operating condition of a network, including voltages, power flows and loading. Short-circuit analysis examines fault currents for a selected fault and network condition. They answer different engineering questions using related model data.
Can ZeroRiskk perform the engineering study for my project?
Yes. Contact us with your study objective, single-line diagram, voltage levels and available equipment data. We can discuss a study scope and the information needed to prepare a proposal.
How should I assess the methods and results?
Check the study scope, equipment inputs, operating case and method assumptions. The tutorial and worksheet provide a reproducible training example, not independent validation of every network or protection scheme. Final design and settings decisions require qualified engineering review.
Can I investigate a relay trip as well?
For a recorded event, use COMTRADE file analysis to inspect waveforms and digital timing. A network model and a disturbance record provide complementary evidence.
