HM5010 Sweep Frequency Response Analyzer Operation Video
Product Overview
The HM5010 Transformer Winding Deformation Tester is designed to test power transformers rated at 6 kV and above, as well as other transformers for special applications. During operation or transportation, power transformers are inevitably subjected to impacts from various fault short-circuit currents or physical collisions. Under the powerful electrodynamic forces generated by short-circuit currents, transformer windings may lose stability, leading to permanent deformations such as local twisting, bulging, or displacement, which can seriously compromise the safe operation of the transformer. In accordance with the national power industry standard DL/T911-2016 and the international standard IEC 60076-18, the frequency response analysis method is used to measure transformer winding deformation. This method involves detecting the amplitude-frequency response characteristics of each transformer winding and conducting longitudinal or transverse comparisons of the test results. Based on the degree of change in these amplitude-frequency response characteristics, the potential deformation of the transformer windings is assessed.
Products Features
• Measures transformer winding characteristics using the sweep method. Without removing the transformer cover or disassembling the unit, it accurately detects winding deformations-such as twisting, bulging, or displacement-in transformers rated at 6 kV and above by analyzing the amplitude-frequency response characteristics of each winding.
• Fast measurement speed: less than 2 minutes per winding, with support for automatic three-phase testing.
• Extremely high frequency accuracy of 0.001%.
• Utilizes digital frequency synthesis for superior frequency stability.
• Features 5000V voltage isolation to fully protect the safety of the test computer.
• Capable of loading 9 curves simultaneously; relevant parameters for each curve are automatically calculated, automatically diagnosing winding deformation and providing diagnostic conclusions.
• Features powerful analysis software; both software and hardware specifications comply with the power industry standard DL/T911-2016 and the International Electrotechnical Commission standard IEC60076-18.
• Runs on the Windows platform and is compatible with Windows 2000, Windows XP, Windows 7, Windows 8, and Windows 10.
• Utilizes a database to store test data, ensuring simple and convenient data management.
• The software features robust management capabilities designed to meet on-site needs, automatically saving measurement data and generating test reports in Word format (requires the corresponding Office software) or as JPG image reports, making it easy for users to generate test reports.
• The software is highly automated; once input and output signals are connected, all measurement tasks can be completed with a single button press.
• The software interface is simple and intuitive. Menus for analysis, storage, report export, and printing only appear automatically after the current step is completed, making the process even more convenient.
