Under the influence of power grid short-circuit impacts, transportation vibrations, and long-term operating stress, transformer windings are highly susceptible to displacement, bulging, or inter-turn short circuits. To address this issue, four transformer winding deformation testers—ZX-BRY01, ZX-BRY02B, ZX-BRY03, and ZX-BRY04—provide users with quantitative diagnostic data from both frequency response method (FRA) and impedance method perspectives, fully meeting the requirements of DL/T911-2016 and DL/T1093-2018 standards.
Its advantages lie in the integration of frequency response and impedance measurement, with a built-in industrial computer operating independently, supporting three-phase automatic analysis and Word report generation. Suitable for provincial power research institutes and maintenance companies to establish long-term databases.
Employs 32-bit ARM+DDS technology, a 10.1-inch touchscreen, and can be operated without a computer. Lightweight and compact (415×350×140mm), suitable for maintenance team inspections and rapid troubleshooting at new energy power plants.
Supports both linear and segmented frequency sweep modes, can load up to 6 curves for comparison, and features an expert intelligent diagnostic system. Suitable for comparative analysis before and after major transformer overhauls.
Based on the BRY03, the impedance method module is enhanced:
Supports internal/external power supply switching, automatically determines if the current exceeds 10A, avoiding the risk of incorrect connection. Suitable for rapid re-inspection after short circuits in 110kV and above transformers.
These four products form a complete technical team from on-site operation and maintenance to scientific research diagnosis, providing quantitative and traceable data assurance for the safe operation of transformers.
