Overview
The Huazheng HZCR-5230 is a portable power quality analyzer designed for field use in substations and industrial sites. It measures 3 voltage channels and 4 current channels simultaneously with class 0.5 accuracy and meets IEC-61010 safety categories (CAT III 1000 V / CAT IV 600 V). The unit captures real-time waveforms, phase diagrams and TRMS values, and stores data locally for post-analysis.

Main capabilities

• Simultaneous measurement: 3 voltage channels + 4 current channels.
• Harmonic analysis up to 51st order with per-harmonic phase angle and THD per phase.
• Event detection: voltage flicker, sag, swell, inrush current and three-phase unbalance.
• Single-button tests: volt-ampere phase test, turns-ratio verification and DC measurement to speed inspections.
• Data storage & export: built-in 8 GB memory, expandable to 32 GB; USB export to PC.
• User interface & protection: 7-inch color touchscreen with English/Chinese switch; double-insulated anti-vibration sheath.
• Power: rechargeable lithium battery 7.4 V, 5200 mAh for extended field operation.

Current sensors & ranges
The analyzer supports up to 6 interchangeable current sensors to cover compact switchgear and large busbar systems without tool changes. Typical sensor types and example ranges:

• Clamp sensors (examples): aperture Ø8 mm, 32×40 mm, Ø50 mm — model-dependent AC ranges (e.g. 10 mA ~ 10 A; 0.1 A ~ 100 A; 1 A ~ 1000 A).
• Flexible coil sensor: AC range typically 10 A ~ 6000 A for large conductors.
• DC current sensor (e.g. 35AD): DC range example 0.1 A ~ 1000 A.

Notes
Designed for rugged field operation: robust enclosure, anti-vibration sheath, multilingual display (English/Chinese) and long battery life to support extended measurement campaigns. Accessories and sensor configurations vary by ordering option.
