• Measuring speed: 1–2 min per winding • Frequency range: 10Hz–10MHz • Frequency accuracy: 0.001% • Output voltage: up to 25Vpp auto-adjusting • Measuring dynamic range: -100dB to 20dB • Isolation protection: 5000V between PC and device • Power supply: AC100–240V 50/60Hz, 3.6kg The Huazheng HZ-600A is a sweep frequency response analyzer designed for detecting winding deformations in transformers of 6kV and above, in compliance with DL/T911-2016 and IEC60076-18 standards. Transformer windings may suffer deformation such as distortion, swelling, or displacement due to short-circuit forces or transportation impact. The HZ-600A identifies these conditions by analyzing amplitude-frequency response curves, eliminating the need for disassembly. With digital frequency synthesis, fast measurement capability, and high frequency stability, the instrument delivers accurate and reliable diagnostic results in as little as two minutes per winding. It allows up to nine curves to be displayed simultaneously, with automatic parameter calculation and diagnostic suggestions to aid engineers in decision-making. Users can easily generate Word or JPG reports for record-keeping and compliance. Lightweight and portable, the HZ-600A is well-suited for field applications in substations, manufacturing facilities, and maintenance projects, providing a comprehensive solution for ensuring transformer safety and reliability.
