1、Main Technical Characteristics 

 l Characteristics of transformer windings are measured with frequency sweep method. Deformations of windings such as distortion, swell or displacement of 6kV and above transformer are measured by detecting amplitude-frequency response characteristics of each winding, not requiring lifting of transformer enclosure or disintegration.

l Quick measuring, measuring of a single winding is within 3 minutes.

l High frequency accuracy, higher than 0.001%.

l Digital frequency synthesis, with higher frequency stability.

l 5000V voltage isolation fully protects safety of the testing computer.

l Able to load 9 curves at the same time and automatically calculate parameters of each curve and diagnose winding deformations to provide the reference diagnosis conclusion.

l Analysis software has powerful functions and software and hardware indicators satisfy national standard DL/T911-2016. (IEC60076-18, optional)

l Software management is humanized with high degree of intelligence. You only need to click a key to complete all measurements after setting of parameters.

l The software interface is concise and vivid, with clear menus of analysis, save, report export, print, etc.

2、Main Technical Indicators

3、Main Features of Test Analysis Software

l Use windows platform compatible with Window 2000/Window XP/Windows 7/windows 8.

l Use database to save test data and render concise and easy data management.

l Able to load 9 curves at the same time and automatically calculate parameters of each curve and diagnose winding deformations to provide the reference diagnosis conclusion.

l Software management function is powerful that takes into full account of site use demand. Measuring data is automatically saved and exported to form Word version test report (require installation of relevant Office software) or JPG photo report to facilitate the user to export test report.

l The software has distinctive humanized feature. Measuring conditions are mostly options, which exempt the need of many inputs and bring about easier operation.

l The software has high degree of intelligence. You only need to click a key to complete all measurements after connection of input and output signals.

l The software interface is concise, vivid and practical.
