Introduction:
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.

equal to or greater than 100MΩ.
2) The withstand power frequency between the working power supply input terminal and
the shell is 2KV (effective value). The experiment lasts 1 minute.
Product Features:
The instrument is integrated with single-phase and three-phase reference power
supply with stable amplitude and constant phase.
The output power of internal reference power supply is large, with maximum of 5A
output, which is especially appropriate for test of low-voltage transformer and test of
number of turns of semi-products during CT and PT manufacturing process.
The instrument can rapidly and accurately test the turn ratio, turns ratio error and
phase difference of current transformer (CT) and potential transformer (PT).
Transfformer Rattiio Testter
The instrument can test single-phase or three-phase transformer, which is suitable for
test of Z-type winding transformer, rectifier transformer and Scott transformer, inverse
Scott transformer and balancing transformer of railway electrical system.
The test accuracy is high, and with 16-digit high-precision AD and high-speed DSP
processor, the instrument can effectively ensure the measurement accuracy and
anti-jamming capability.
Non-partial discharge voltage regulating output is used for the instrument, it's rapid
