Three-Phase Measurement System (LabVIEW Project)

This repository contains a LabVIEW-based measurement and visualization system for analyzing three-phase electrical signals.
The project was developed as part of a Masters course final project.

📖 Project Overview

• Objective
  Design and implement a LabVIEW system that measures and visualizes three-phase voltage and current signals in both time domain and phasor (vector) representation.

• Features

  • Real-time oscilloscope plots of three-phase voltage and current.
  • Phasor diagram visualization (vector representation).
  • Adjustable phase shift & scaling for simulation and testing.
  • Degree ↔︎ radian conversion for angular math.

⚡ How It Works

1. Inputs: u1, u2, u3 (phase voltages) and i1, i2, i3 (phase currents).
2. Processing (selected stages):
   • Current/voltage scaling and splitting.
   • ±25° phase shifting blocks for test scenarios.
   • Degree→radian conversion for vector math.
3. Outputs:
   • Oscilloscope View: time-domain waveforms of voltages & currents.
   • Phasor Display: vector magnitudes and relative angles.
