Product Application

DBRB-V Transformer Winding Deformation Tester has two measuring methods: frequency response method and low-voltage short-circuit impedance method. Two different methods are used to measure power transformer winding, fully reflect the features of transformer winding and correctly diagnose and analyze winding deformation. The perfect combination of two methods can save test time and improve working efficiency. 

The transformer winding deformation tester (frequency response method) is used to test 6kV and above power transformer as well as other special transformer. It is inevitable that power transformer is subject to all kinds of short-circuit current impacts or physical strike in the process of operation or transportation.

The transformer winding deformation tester (low-voltage impedance method) is an intelligent instrument. It is specially used for measuring impedance attributes of high or medium power transformer. 

Main Features

-The frequency precision of frequency response method is very high, higher than 0.001%. 
-The frequency response method adopts digital frequency synthesis, and frequency stability is higher. 
-The frequency response method adopts 5000V voltage to isolate, which can ensure the safety of test computer. 
-Be able to load 9 curves at the same time; automatically calculate relevant parameters of each curve; automatically diagnose deformation condition of winding and provide conclusions for reference 
-Both Software and hardware conform to national electric power industry standards - IEC/IEEE/ANSI. 
-The short-circuit impedance method can be used to measure the impedance of any transformer regardless of its capacity. 
-Waveform atlas of testing current and voltage is displayed during the test in order to facilitate real-time monitoring. 
-The short-circuit impedance method can measure the inductance and zero-sequence impedance of the transformer. 
-Use the database to store and manage test data
-The software is highly intelligent. After input and output signal are well connected, only pressing one button can complete all measuring work.
-Simple and user-friendly software interface
