Product Description

Feature of KDRB-X Transformer Winding Deformation Tester:

1.The acquisition control uses a high-speed, highly integrated microprocessor.
2.This instrument comes with an industrial computer for independent use, without a laptop, and can also be connected to a laptop through a USB interface.
3.The instrument automatically analyzes and judges the test results and generates electronic documents (Word) for storage and printing.
4.The instrument also meets the technical requirements of the power standard DL/T911-2016 "Frequency Response Analysis Method for Power Transformer Winding Deformation" and DL/T1093-2008 "Guidelines for Detection and Judgment of Power Transformer Winding Deformation by Reactance Method".
5.High-speed dual-channel 16-bit A/D sampling (the waveform curve changes significantly when the tap switch is changed in the field test).
6.The frequency response method hardware movement uses DDS dedicated digital high-speed sweep frequency technology (USA). Through testing, it can accurately diagnose winding distortion, bulging, displacement, tilt, turn-to-turn short-circuit deformation and phase-to-phase contact short-circuit and other faults.
7.The frequency response method has the dual measurement system functions of linear sweep frequency measurement and segmented sweep frequency measurement, and is compatible with the measurement modes of the two current domestic technical schools.
8.The amplitude-frequency characteristics of the frequency response method meet the national technical indicators for amplitude-frequency characteristic testers. The horizontal axis (frequency) has two types of linear and logarithmic divisions, so the printed curve can be a linear division curve or a logarithmic division curve, and the user can choose according to actual needs.
9.The impedance method adopts a three-phase wiring single-phase measurement method. It only needs to short-circuit the low-voltage side and connect the three phases on the high-voltage side at one time. The short-circuit impedance of each phase can be calculated by automatic measurement at one time.
10.The impedance method can synchronously measure voltage, current, and frequency, and display the real-time waveform of the test.
11. The impedance method can use the internal power supply or an external power supply.
