XTRZ1002 Transformer Winding Deformation Tester

Estimated delivery : 45 Days; MOQ : 1 PC
Product Introduction Overview
Frequency Response Method (Chinese and English versions available) Laptop not included
Three-phase automatic
Support Windows 32-bit/64-bit, Android
The three-phase fully automatic measurement method can be used.
Connect the three-phase measurement lines at one time, without changing the lines after measuring one phase each time. The three-phase measurement is completed automatically and the measurement results are saved automatically.

Features :
The acquisition control adopts a high-speed, highly integrated microprocessor.
USB interface for communication between laptop and instrument.
The laptop computer can communicate with the instrument through a wireless Bluetooth interface or a wireless WIFI interface (optional). The wireless WIFI interface can be used more conveniently on tablet computers and smart phones.
The hardware movement adopts DDS dedicated digital high-speed frequency scanning technology (USA). Through testing, it can accurately diagnose faults such as winding distortion, bulging, displacement, tilt, turn-to-turn short circuit deformation and phase-to-phase contact short circuit.
High-speed dual-channel 16-bit A/D sampling (on-site test, changing the tap switch, the waveform curve has obvious changes).
The signal output amplitude is software-adjustable, with a maximum peak amplitude of ±10V.
The computer automatically analyzes the test results and generates electronic documents (Word).
The instrument has dual measurement system functions of linear frequency sweep measurement and segmented frequency sweep measurement, and is compatible with the measurement modes of the two current domestic technical schools.
The amplitude-frequency characteristic meets 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 or logarithmic division curve, and users can choose according to actual needs.
Automatic analysis system for test data
Compare the winding similarity between the three phases AA, B and CC horizontally
The analysis results are:
①Good consistency
②Good consistency
③Poor consistency
④The consistency is very poor,
Longitudinal comparison A A- -AA, B B- -BB, C C- -CC Retrieve the original data and current data in phase to compare the winding deformation
The analysis results are:
①Normal winding
② Mild deformation
③ Moderate deformation
④Severe deformation
Word electronic documents can be automatically generated for saving and printing.
The instrument fully meets the technical requirements of the power standard DL/T911-2004 "Frequency Response Analysis Method for Power Transformer Winding Deformation".
