SFRA Sweep Frequency Response Analysis IEC60076-18 Transformer Winding Deformation Tester

1. Transformer Winding Deformation Tester Overview

The HDRZ301B tester consists of the tester host, test notebook, test cable and other accessories, as shown in the following figure.

2. Transformer Winding Deformation Tester Tester host

The HDRZ301B tester host is used to receive test commands issued by the test notebook, and send the test results back to the test notebook. The tester host and tester notebook are connected via an Ethernet cable.

3. Transformer Winding Deformation Tester Tester notebook

Test notebook pre-installs transformer winding deformation testing software.The test software is used to set the test parameters, start or stop the testing process, store the test results, analyze and compare the test results.

4. Transformer Winding Deformation Tester Test cable

The test cable and connector provided by the tester should not be changed in any way.

The test cable is made of low loss RG-58 RF coaxial cable, the number of the cable is 3.One end of the cable is connected to the test panel with a standard BNC connector and the other end of the clamp is connected to the measured winding of the transformer. Among them, two cables which connected to the panel excitation interface and the reference interface are connected to the excitation end of the winding, the cable connected to the panel response interface is connected to the response end of the winding.

The shield of the cable and the ground connection of the transformer shell should be connected reliably.
