YCPQA-9901 Power Quality Analyzer
Power quality Analyzer can conduct online long-term or short-term survey about electric net voltage, current and power. It can also measure circuit loss, estimate electric system power quality, and examine functions of power correction instrument. Meanwhile, this instrument provides reliable detection means to help make an electric net harmonic pollution reducing plan by analyzing varied harmonic sources and choosing the proper harmonic filter. The floating-point Digital Signal Processing (DSP) enables entire data collected by power quality analytical instrument to be processed at the same time, that is, no time error. 32-bit 260M high speed ARM9 Central Processing Unit enables the instrument to have the basic functions of PC can conduct analyses independently without PC(laptop)
