Power System Stability Monitor Kit with Arduino Mega
Build a Real-Time Three-Phase Power Stability Monitor with Arduino Mega
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform three ZMPT101B voltage sensors into a laboratory-grade power system stability monitor that captures 10,000 samples per second. Designed for B.Tech power systems labs and Smart India Hackathon energy challenges, this kit detects frequency deviations, total harmonic distortion (THD), and voltage unbalance across a three-phase source in real time.
What You'll Build
You'll assemble a DIN rail-mountable instrument that displays live frequency, THD, and phase voltage balance on a 1.8-inch TFT screen while timestamping every grid anomaly to a microSD card. The result is a tool that rivals benchtop power quality analyzers in functionality, built by your own hands and ready for field measurements or lab demonstrations.
What You'll Learn
- Sampling AC waveforms at 10 kHz with ZMPT101B sensors and zero-cross detection
- Computing RMS voltage and running Fast Fourier Transform (FFT) to extract THD
- Implementing three-phase voltage unbalance algorithms per IEC standards
- Logging time-stamped power events using DS3231 RTC and microSD data storage

| Time to first working build | Days of debugging | Hours, with step-by-step guidance |
| Shipping coordination | Multiple sellers, multiple delays | One shipment from Bengaluru in 3-5 days |
Who This Kit Is For
Ideal for B.Tech ECE and EEE students working on power quality analysis for Smart India Hackathon or final-year projects. Also suits research scholars at IITs, NITs, VIT, and BITS needing a portable three-phase monitor, and ATL Tinkering Labs mentors demonstrating real-world grid instability concepts. The advanced nature demands prior soldering experience and familiarity with Arduino IDE.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to talk to the AI companion that knows every wire and line of code; WhatsApp backup is available 12x7 for stubborn hang-ups.
Can I use this kit with a single-phase supply?
Yes, by connecting just one ZMPT101B, but the unbalance detection and three-phase THD averaging features will be disabled in the code.
Do I need external isolation transformers?
No. The ZMPT101B modules contain onboard voltage transformers that provide galvanic isolation rated for 250V AC.
Is calibration required after assembly?
The open-source sketch includes an auto-calibration routine that you run once using a known 230V reference source to set scaling factors.
ZMPT101B samples voltage at 10kHz. Detects frequency deviations, THD and voltage unbalance in real time.
