Weshine® OC and SC Test on Transformer,Transformer LV Short-circuit Impedance Tester is not provided with an external voltage regulator and adopts the primary connection mode. It begins the three-phase testing and calculates impedance error percentage automatically when the parameter is entered and provides intuitive results. This is a rapid tester which detects winding deformation of transformers on site.

Weshine® Sweep Frequency Response Analyzer for SFRA transformer test with CE certificate, high quality and accuracy, Invented and produced according to national standards, complete electric testing solution available. Contact us for more details of Sweep Frequency Response Analyzer for SFRA transformer test from Weshine®! Weshine® invented the VS-1000 series of Sweep Frequency Response Analyzer for SFRA transformer test detects potential mechanical and electrical problems that other methods are unable to detect. Major utilities and service companies have used the SFRA transformer test method for more than a decade. The measurement is easy to perform and will capture a unique fingerprint of the transformer. The measurement is compared to a reference fingerprint and gives a direct answer if the mechanical parts of the transformer are unchanged or not. Deviations indicate geometrical and/or electrical changes within the transformer.

Weshine® invented the Turns Ratio Tester for Turns Ratio Test with CE certificate, high quality and accuracy, Invented and produced according to national standards, complete electric testing solution available. Contact us for more details of Turns Ratio Tester for Turns Ratio Test from Weshine!

Given the different functional requirements of grid protection systems, testing capabilities require a higher level of sophisticated testing hardware and software to analyze the operation of the entire protection system (or individual protection components) under "real life" situations. Similar improvements in simplifying the user interface and software control of test instruments are further necessary to meet these expanding test capabilities. Rest assured, no matter how complex, every aspect of relay testing can be easily handled with Weshine®'s comprehensive line of Relay Circuit Tester (VS-JB900 series). Plus, whether you're testing traditional electromechanical relays or modern IEC 61850 networked devices, our rugged products deliver the high power you need while still being portable for practical testing.
