Fault Analysis Kit: Symmetrical and Unsymmetrical Fault Currents

Approx. component budget: Rs. 4,000 - 8,000

Objective

Verify fault current calculations with measurements on a small system.

What you will build

A 3-phase low-voltage model with a switchable fault box (L-G, L-L, L-L-G, 3-phase), current sensors and software to compare measured fault currents with calculated ones.

Results you can expect

• Measured vs calculated fault current for 4 fault types
• Percentage error
• Sequence-component calculation in Python
• And a voltage sag profile

What you will learn

Symmetrical components, fault calculations and the connection between theory and measurement.

Tools and notes

3-phase variac, small transformer, current sensors, data logger, Python or MATLAB. Use a current-limited, low-voltage test and fuses on every phase.

Resume points from this project

• Built and tested Fault Analysis Kit: Symmetrical and Unsymmetrical Fault Currents; objective: verify fault current calculations with measurements on a small system.
• Measured and analysed measured vs calculated fault current for 4 fault types and percentage error; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
