XHBX1501 Transformer winding Deformation Tester

  Product Description   Transformer winding deformation tester (FRA) is used to testing 6KV and above voltage power transformers and other special function transformers. power transformers in operation or during transport will inevitably suffer the physical shock of various fault or short circuit current, transformer windings may lose stability in the role of a powerful electric power generated by the short circuit current, leading to local distortion, drum kits and other permanent deformation or displacement phenomenon, which will seriously affect the safe operation of the transformer. According to the national power industry standard DL / T911-2004 using winding deformation analysis method to measure the frequency response of the transformer, is amplitude-frequency response characteristics detected by each transformer windings, and the test results were vertical or horizontal comparison, according to the amplitude-frequency response characteristic changes degree of deformation to determine the transformer winding deformation may occur.
Transformer winding deformation test instrument (frequency response method) is composed of measuring and analyzing software part, measuring part is the black box consists signal generation and the signal measurement. Analysis is done by laptop, measurement part via USB or network connected to the laptop.       Technical data The main technical parameters of the Transformer winding deformation test instrument method (frequency response analysis, FRA )  Test host and PC interface: USB or network  Source: Instrument with a channel output signal as the excitation signal frequency; signal output to standard sine wave output signal amplitude can be adjusted by software, the maximum was 10V, the signal output impedance of 50 ohms.  Two acquisition channels, a collection of signal acquisition, a response signal, is used to calculate the transfer function.  The incentive for fixed channel measurement range: 10V; response channel multi range, automatic adjustment range in the measurement process, the maximum input signal is below 25V  Acquisition channel quantization precision: 12 Acquisition of the maximum static error: 0.5%.  The maximum storage capacity of each channel: 64K samples  The highest sampling rate for each channel: 20Msps.  Acquisition channel input impedance: 1M.  Sweep frequency measurement range: 10Hz - 10MHz.  Scanning mode: Linear distribution or logarithmic distribution of sweep frequency method  Precision of scanning frequency: The frequency of the signal source output sine signal precision is not greater than 0.01%.  Frequency sweep measurement points: a fixed pattern or user customization.  In line with the national electric power industry standard DL/T911-2004.
