Product Overview
The HZDZ-I Power Quality Online Monitoring Device utilizes an advanced 32-bit DSP processor to deliver comprehensive power grid analysis. It integrates high-speed sampling, calculation, statistics, and communication into a single robust unit.
Key Monitoring Capabilities
- Real-time tracking of harmonic content (up to 63rd) and total harmonic distortion (THD).
- Advanced analysis of three-phase voltage unbalance, flicker, and voltage fluctuations.
- Precision measurement of frequency, active/reactive power, and true power factor.
- Monitoring of true RMS values and sequence components (positive/negative).
Environmental & Operational Advantages
- Resists high heat, humidity, and salt spray for tropical island use.
- Runs stably at −40°C, cold-proof and anti-condensation.
- IEC compliant, complete calibration certificates provided.
- Local support: spares, on-site training, and instrument calibration.
