When comparing comprehensive power quality analyzers, procurement personnel often encounter issues such as inconsistent range specifications and vague functional descriptions, requiring item-by-item verification to determine whether the equipment meets on-site requirements. The following outlines key parameters and configurations from the perspective of selection points, facilitating quick comparison.
AC voltage direct measurement range 50–750V, AC current 0.5–600A; if higher voltage or larger current coverage is required, the range can be extended via external PTs and CTs. During selection, confirm whether the device supports ratio settings.
The device should be capable of measuring apparent power, active power, reactive power, power factor (0–1.0), and active energy (0–99999.9kW·h), meeting the basic needs of on-site power quality and energy consumption accounting.
Built-in digital oscilloscope function enables real-time viewing of voltage and current instantaneous waveforms; vector diagram display helps determine whether metering equipment wiring is correct, reducing manual troubleshooting time.
7-inch color LCD screen with touch buttons and buzzer prompts for operation; 80mm high-speed micro thermal printer enables on-site printing of measurement data in Chinese; supports computer serial communication for easy record keeping and report generation.
