◆ High-speed, high-integration microprocessors are used for collection control. ◆ USB communication interface between the PC and the instrument. ◆ The hardware core utilizes DDS digital high-speed sweep technology (USA) to accurately diagnose faults such as twisted windings, blisters, displacement, tilt, inter-turn short-circuit deformation, and inter-phase contact short-circuit through testing. ◆ High-resolution dB value measurement, dual-channel 16-bit A/D (changing the tap switch during on-site testing results in a significant output change). ◆ Signal output amplitude is adjustable by software, with a peak of ±10V. ◆ The computer generates electronic documents (WORD) from test results. ◆ The finished circuit board is specially treated on the surface, with resistance to water and harmful gas contamination. ◆ Laptop computers and measurement instruments are powered by isolated power supplies to eliminate external interference. ◆ The instrument features a dual measurement system with both linear sweep and segmented sweep measurement functions, compatible with the current domestic measurement modes of two technical schools. ◆ The amplitude-frequency characteristics meet the technical specifications of the amplitude-frequency characteristic tester. The horizontal axis (frequency) has both linear and logarithmic divisions, allowing printed curves to be either linear or logarithmic, with the user choosing based on actual needs. ◆ An automatic data analysis system for detection data compares the winding similarity between phases A, B, and C (results: ① Very good consistency; ② Good consistency; ③ Poor consistency; ④ Very poor consistency) and performs winding deformation comparisons by retrieving original data with the current data in phase A-A, B-B, and C-C (results: ① Normal winding; ② Mild deformation; ③ Moderate deformation; ④ Severe deformation). ◆ Automatically generates Word electronic documents for saving and printing. ◆ Fully meets the technical requirements of the power standard DL/T911-2004 "Frequency Response Analysis Method for Power Transformer Winding Deformation."
