The HCRZ-II Comprehensive transformer Winding Deformation Tester employs two distinct testing methods—the Frequency Response Method and the Low-Voltage Short-Circuit Impedance Method—to measure and diagnose the windings of medium-to-large-scale transformers. By comprehensively reflecting the winding characteristics of the transformer, this product stands as the first of its kind in the nation to feature such industry-leading technology.

Product Features

Utilizes a Windows-based platform, compatible with Windows 2000, Windows XP, and Windows Vista.

The accompanying software supports remote debugging, diagnostics, maintenance, and upgrades of the device, facilitating convenient on-site technical support from the manufacturer.

Automatically calculates relevant test parameters, diagnoses the extent of winding deformation, and provides reference conclusions for the diagnosis.

Features robust software management capabilities designed with on-site operational needs in mind; it automatically saves environmental condition parameters to serve as a basis for subsequent transformer winding deformation diagnostics. Measurement data is automatically saved to disk, and a color printing function is included to facilitate the generation of test reports for users.

The software features a highly user-friendly design; most measurement conditions are presented as selectable options, minimizing the need for extensive manual data entry while on-site and thereby enhancing user convenience.

The software demonstrates a high degree of intelligence; once the input and output signals are properly connected, the entire measurement process can be completed simply by pressing a single button.

Housed in a dedicated shock-proof case, the device is protected against vibration and moisture, ensuring ease of portability and handling.
