Description
UNI-T UT285C is an advanced three-phase power quality analyzer, combining multifunctionality with an intuitive interface. Its features include simultaneous measurement of four-channel current and voltage, assessment of peak values, imbalance factors, and various power parameters. The device displays real-time waveforms, harmonic ratio bar charts, and dynamically captures instantaneous changes. With a robust design and alarm generation capabilities, it offers comprehensive power quality analysis in a compact package.
Features
- Real-time waveform display (4 channels voltage/current);
- True RMS values of voltages and currents;
- DC components of voltages;
- Peak current and voltage values;
- Minimum and maximum half-cycle RMS current and voltage values;
- Measurement of each harmonic up to order 50;
- Bar charts show harmonic ratios of current and voltage of each phase;
- Total harmonic distortion (THD);
- Active, reactive, apparent power, by phase and cumulative;
- Transformer K factor, power factors (PF) and displacement factors (DPF or Cosφ);
- Short-term voltage flicker (PST);
- Three phase unbalance (current and voltage);
- USB interface/PC software
