According to the technical requirements of GB/T 17215.302—2013 for 0.2S class electricity meter calibration devices, a comprehensive power quality analyzer must meet indicators such as voltage/current measurement error ≤±0.1% and harmonic analysis order of no less than 50. The TX-8200 Comprehensive Power Quality Analyzer is designed according to this standard. The following lists the selection points from the perspective of engineering parameters.
It can simultaneously connect three-phase voltage and current signals, and supports acquisition via clamp-on transformers or Rogowski coils, adapting to different on-site wiring conditions; the internal high-speed ADC and DSP perform fast Fourier transform to calculate RMS values, phase, power, and harmonic components in real time.
The voltage/current measurement error is ≤±0.1%, meeting the comparison requirements of 0.2S class gateway metering and distribution monitoring; the harmonic analysis range can be found in the equipment technical manual, covering conventional power quality monitoring frequency bands.
The calculation results are presented in the form of waveform diagrams, spectrum diagrams, trend diagrams, vector diagrams, etc., making it convenient to check three-phase unbalance and harmonic distribution during design selection; it is equipped with a high-speed micro thermal printer, with Chinese prompts to print all measurement and calculation data.
Touch button operation, with buzzer response to button operation; screen size 80mm; provides a computer serial communication interface, comprehensively saves and records test data, and can directly print reports.
It is suitable for scenarios such as power frequency on-site testing in power transmission and transformation, power quality surveys of distribution systems, comparison of gateway metering devices, and harmonic source troubleshooting, providing data support for design selection and operation evaluation.
