KGZW-30B Power Harmonic Tester

Produk Inleiding
With the vigorous development of China’s national economy, the power load increases sharply, especially the impact and nonlinear load capacity continues to grow, resulting in power quality problems such as waveform distortion, voltage fluctuation and flicker and three-phase unbalance.
The KGZW-30B harmonic tester introduced by our company is a high performance multi-function harmonic tester. Using DSP+ARM+CPLD core, 3.2 “Groot skerm LCD (320×240 lattice) display, so that the structure is more compact, more powerful, more convenient display. Background management analysis software, rich functions, maklik om te bedryf.

KGZW-30B Power Harmonic Tester

Produk Eienskappe
1, Veilig en betroubaar
The voltage input adopts a high voltage isolation module (2000V, response time ≤2μS), and the current input adopts a AC current clamp (0 ~ 50 KHZ,0 ~ 5Arms) to isolate the input signal from the measurement system. This not only makes KGZW-30B safe, reliable and convenient in use, but also greatly improves the anti-interference ability.
2, maklik om te gebruik
Portable structure, klein grootte, ligte gewig, one person can carry the instrument to the field test; Built-in high-performance lithium battery, no external power supply.
3, hoë akkuraatheid
Harmonics meet the national standard A level instrument requirements. For harmonics, three-phase unbalance, flicker and fluctuation, the benchmark algorithm is adopted without approximate calculation, high-precision A/D (16-bit) is adopted, and the collection rate is 12.8 kHz.
4. Strong software function
Using DSP+ARM+CPLD kernel, the processing speed is fast, and the software functions are rich, which makes ZKD35-1 suitable for complex test work and data processing work, and greatly improves the test efficiency and level.
