ZC-203D Special Transformer Ratio Tester is the second generation of transformer ratio test equipment newly launched by our company, which can be used for test of three-phase transformer in power system, especially for Z-type winding transformer, rectifier transformer and balancing transformer. With advantages of large-screen LCD display, English menus and English characters printout, friendly human-computer interface, functional maturation and easy operation, the tester is an ideal instrument for manufacturers of power system, transformer and railway electrical system to make tests on transformation ratio, group polarity and angle.
