Product Introduction

The XL-801R dynamic waveform standard electric energy meter series can be used as an AC standard meter and harmonic standard meter, with options for single/three-phase measurement. It measures harmonics from 2nd to 50th order, with an accuracy class of 0.05 and harmonic accuracy of 0.2. It can be used for testing and calibration of dynamic performance of AC voltage sources, AC current sources, AC power sources, dynamic/harmonic voltage sources, dynamic/harmonic current sources, dynamic harmonic power sources, harmonic energy meters, and AC energy meters. It is suitable for power departments, metrology departments, quality inspection departments, research institutions, universities, and enterprises engaged in production and R&D of energy meters, distribution terminals, power management, load control, power quality, and reactive power compensation.

Main Functions

• High Measurement Accuracy: Power and Energy Measurement Accuracy Class 0.05 Class , voltage and current measurement accuracy class 0.05, suitable for measurement and calibration of AC quantities, harmonics, and dynamic performance.
• Wide Measurement Range: Measurement Range 30-420V, 50mA-120A , meeting the traceability and calibration requirements for dynamic performance of AC energy meters, harmonic energy meters, and AC meters.
• Automatic Range Switching, High Integration: Voltage 30-420V uses a pair of terminal inputs, current 50mA-120A uses a pair of input terminals, with full-range automatic range switching to ensure accuracy indicators across the measurement range.
• Synchronous Sampling of Voltage and Current: Voltage and current use synchronous sampling technology, controlled by a synchronous clock, sampling voltage and current values at the same moment. Power and energy are calculated by dot product sum, eliminating measurement errors caused by asynchronous sampling of voltage and current, improving energy measurement accuracy.
• 2~50 Order Harmonic Measurement Harmonic Measurement Accuracy 0.2% , meeting current JJG 1106-2015, AC dynamic performance, and IR46 test requirements.
• 24-bit High-speed ADC: Uses industry-leading 24-bit ADC chips and multi-core DSP processors + DDR large-capacity memory, with high sampling rate, strong computing power, and high accuracy.
• High Annual Stability Uses high-precision imported components, with typical annual measurement stability of 100 PPM/year , allowing long-term use without calibration.
• Measurement Value Statistical Analysis: Can statistically analyze amplitude, power maximum, minimum, variation, and standard deviation, helping analyze short-term stability and trends.
• Human-Machine Interaction: Equipped with a large-size touch display screen , with clear and intuitive value display, and multiple interfaces including RJ45, RS232, USB, facilitating the construction of automated test systems.
