Electrical measurements
Power Quality Lab
How can sampled AC waveforms reveal power-quality problems?
Completed · Tested · 2026
Context
It turns sampled voltage and current into reproducible engineering evidence while documenting the gap between simulation and a safe, calibrated physical instrument.
Design problem
How can sampled AC waveforms reveal power-quality problems?
Approach
Preserve simultaneous voltage and current samples; interpolate positive-going zero crossings for frequency; classify against explicit thresholds.
Validation
Deterministic synthetic waveforms, explicit classification thresholds, and a public unittest suite.
Result
A reproducible report of electrical measurements and the classified condition for each synthetic scenario.
Limitations
Simulation only. ADC quantization, isolation, harmonics, calibration drift, and electrical safety are not modeled.
What I would improve next
A hardware extension would need isolated sensing and calibration in a safe low-voltage test setup.
